Ivanti has rolled out security updates for a critical flaw in Virtual Traffic Manager (vTM) that could be exploited to achieve an authentication bypass and create rogue administrative users. The vulnerability, tracked as CVE-2024-7593, has a CVSS score of 9.8 out of a maximum of 10.0. "Incorrect implementation of an authentication algorithm in Ivanti vTM other than versions 22.2R1 or 22.7R2 allows a remote unauthenticated attacker to bypass authentication of the admin panel," the company said in an advisory. It impacts the following versions of vTM - 22.2 (fixed in version 22.2R1) 22.3 (fixed in version 22.3R3, available week of August 19, 2024) 22.3R2 (fixed in version 22.3R3, available week of August 19, 2024) 22.5R1 (fixed in version 22.5R2, available week of August 19, 2024) 22.6R1 (fixed in version 22.6R2, available week of August 19, 2024) 22.7R1 (fixed in version 22.7R2) As temporary mitigation, Ivanti is recommending customers to limit admin access to th

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

A new zero-day pre-authentication remote code execution vulnerability has been disclosed in the Apache OFBiz open-source enterprise resource planning (ERP) system that could allow threat actors to achieve remote code execution on affected instances. Tracked as CVE-2024-38856 , the flaw has a CVSS score of 9.8 out of a maximum of 10.0. It affects Apache OFBiz versions prior to 18.12.15. "The root cause of the vulnerability lies in a flaw in the authentication mechanism," SonicWall, which discovered and reported the shortcoming, said in a statement. "This flaw allows an unauthenticated user to access functionalities that generally require the user to be logged in, paving the way for remote code execution." CVE-2024-38856 is also a patch bypass for CVE-2024-36104 , a path traversal vulnerability that was addressed in early June with the release of 18.12.14. SonicWall described the flaw as residing in the override view functionality that exposes critical endpoi

Sina Kheirkhah of Summoning Team, who is credited with discovering and reporting the flaw, described it as a "very simple" bug that could be exploited by a "remote unauthenticated attacker to create an administrator user and login." Besides updating to the latest version, Progress Software is urging cust

Two recently disclosed security flaws in Ivanti Connect Secure (ICS) devices are being exploited to deploy the infamous  Mirai botnet . That's according to  findings  from Juniper Threat Labs, which said the vulnerabilities  CVE-2023-46805 and CVE-2024-21887  have been leveraged to deliver the botnet payload. While CVE-2023-46805 is an authentication bypass flaw, CVE-2024-21887 is a command injection vulnerability, thereby allowing an attacker to chain the two into an exploit chain to execute arbitrary code and take over susceptible instances. In the attack chain observed by the network security company, CVE-2023-46805 is exploited to gain access to the "/api/v1/license/key-status/;" endpoint, which is vulnerable to command injection, and inject the payload. As  previously outlined  by Assetnote in their technical deep dive of the CVE-2024-21887, the exploit is triggered by means of a request to "/api/v1/totp/user-backup-code/" to deploy the malware. &quo

Threat actors are actively exploiting critical vulnerabilities in OpenMetadata to gain unauthorized access to Kubernetes workloads and leverage them for cryptocurrency mining activity. That's according to the Microsoft Threat Intelligence team, which  said  the flaws have been weaponized since the start of April 2024. OpenMetadata is an  open-source platform  that operates as a metadata management tool, offering a unified solution for data asset discovery, observability, and governance. The flaws in question – all discovered and credited to security researcher Alvaro Muñoz – are listed below - CVE-2024-28847  (CVSS score: 8.8) - A Spring Expression Language (SpEL) injection vulnerability in PUT /api/v1/events/subscriptions (fixed in version 1.2.4) CVE-2024-28848  (CVSS score: 8.8) - A SpEL injection vulnerability in GET /api/v1/policies/validation/condition/<expr> (fixed in version 1.2.4) CVE-2024-28253  (CVSS score: 8.8) - A SpEL injection vulnerability in PUT /api/v

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  a critical security flaw impacting JetBrains TeamCity On-Premises software to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, tracked as CVE-2024-27198 (CVSS score: 9.8), refers to an authentication bypass bug that allows for a  complete compromise  of a susceptible server by a remote unauthenticated attacker. It was addressed by JetBrains earlier this week alongside CVE-2024-27199 (CVSS score: 7.3), another moderate-severity authentication bypass flaw that allows for a "limited amount" of information disclosure and system modification. "The vulnerabilities may enable an unauthenticated attacker with HTTP(S) access to a TeamCity server to bypass authentication checks and gain administrative control of that TeamCity server," the company  noted  at the time. Threat actors have been observed weaponizing the twin flaws to de

Cybersecurity researchers have identified two authentication bypass flaws in open-source Wi-Fi software found in Android, Linux, and ChromeOS devices that could trick users into joining a malicious clone of a legitimate network or allow an attacker to join a trusted network without a password. The vulnerabilities, tracked as CVE-2023-52160 and CVE-2023-52161, have been discovered following a security evaluation of  wpa_supplicant  and Intel's iNet Wireless Daemon ( IWD ), respectively. The flaws "allow attackers to trick victims into connecting to malicious clones of trusted networks and intercept their traffic, and join otherwise secure networks without needing the password," Top10VPN  said  in a new research conducted in collaboration with Mathy Vanhoef, who has previously uncovered Wi-Fi attacks like  KRACK ,  DragonBlood , and  TunnelCrack . CVE-2023-52161, in particular, permits an adversary to gain unauthorized access to a protected Wi-Fi network, exposing exis

ConnectWise has released software updates to address two security flaws in its ScreenConnect remote desktop and access software, including a critical bug that could enable remote code execution on affected systems. The vulnerabilities are listed below - CVE-2024-1708 (CVSS score: 8.4) - Improper limitation of a pathname to a restricted directory aka "path traversal" CVE-2024-1709 (CVSS score: 10.0) - Authentication bypass using an alternate path or channel The company deemed the severity of the issues as critical, citing they "could allow the ability to execute remote code or directly impact confidential data or critical systems." Both the vulnerabilities impact ScreenConnect versions 23.9.7 and prior, with fixes available in version 23.9.8. The flaws were reported to the company on February 13, 2024. While there is no evidence that the shortcomings have been exploited in the wild, users who are running self-hosted or on-premise versions are recommended

Ivanti has alerted customers of yet another high-severity security flaw in its Connect Secure, Policy Secure, and ZTA gateway devices that could allow attackers to bypass authentication. The issue, tracked as  CVE-2024-22024 , is rated 8.3 out of 10 on the CVSS scoring system. "An XML external entity or XXE vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x) and ZTA gateways which allows an attacker to access certain restricted resources without authentication," the company  said  in an advisory. The company said it discovered the flaw during an internal review as part of its ongoing investigation into multiple security weaknesses in the products that have come to light since the start of the year, including  CVE-2023-46805, CVE-2024-21887 ,  CVE-2024-21888, and CVE-2024-21893 . CVE-2024-22024 affects the following versions of the products - Ivanti Connect Secure (versions 9.1R14.4, 9.1R17.2, 9.1R18.3, 22.4R2.2, a

A critical security flaw has been disclosed in Fortra's GoAnywhere Managed File Transfer (MFT) software that could be abused to create a new administrator user. Tracked as  CVE-2024-0204 , the issue carries a CVSS score of 9.8 out of 10. "Authentication bypass in Fortra's GoAnywhere MFT prior to 7.4.1 allows an unauthorized user to create an admin user via the administration portal," Fortra  said  in an advisory released on January 22, 2024. Users who cannot upgrade to version 7.4.1 can apply temporary workarounds in non-container deployments by deleting the InitialAccountSetup.xhtml file in the install directory and restarting the services. For container-deployed instances, it's recommended to replace the file with an empty file and restart. Mohammed Eldeeb and Islam Elrfai of Cairo-based Spark Engineering Consultants have been credited with discovering and reporting the flaw in December 2023. Cybersecurity firm Horizon3.ai, which published a  proof-of-co

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  a now-patched critical flaw impacting Ivanti Endpoint Manager Mobile (EPMM) and MobileIron Core to its Known Exploited Vulnerabilities ( KEV ) catalog, stating it's being actively exploited in the wild. The vulnerability in question is  CVE-2023-35082  (CVSS score: 9.8), an authentication bypass that's a patch bypass for another flaw in the same solution tracked as CVE-2023-35078 (CVSS score: 10.0), which was actively exploited in attacks targeted Norwegian government entities as a zero-day in April 2023. "If exploited, this vulnerability enables an unauthorized, remote (internet-facing) actor to potentially access users' personally identifiable information and make limited changes to the server," Ivanti  noted  in August 2023. All versions of Ivanti Endpoint Manager Mobile (EPMM) 11.10, 11.9 and 11.8, and MobileIron Core 11.7 and below are impacted by the vulnerability. Cyb

Cybersecurity researchers have  developed  a proof-of-concept (PoC) code that exploits a  recently disclosed critical flaw  in the Apache OfBiz open-source Enterprise Resource Planning (ERP) system to execute a memory-resident payload. The vulnerability in question is  CVE-2023-51467  (CVSS score: 9.8), a bypass for another severe shortcoming in the same software ( CVE-2023-49070 , CVSS score: 9.8) that could be weaponized to circumvent authentication and remotely execute arbitrary code. While it was fixed in  Apache OFbiz version 18.12.11  released last month, threat actors have been observed attempting to exploit the flaw, targeting vulnerable instances. The latest findings from VulnCheck show that CVE-2023-51467 can be exploited to execute a payload directly from memory, leaving little to no traces of malicious activity. Security flaws disclosed in Apache OFBiz (e.g.,  CVE-2020-9496 ) have been  exploited  by threat actors in the past, including by threat actors associated wit

A pair of zero-day flaws identified in Ivanti Connect Secure (ICS) and Policy Secure have been chained by suspected China-linked nation-state actors to breach less than 10 customers. Cybersecurity firm Volexity, which  identified  the activity on the network of one of its customers in the second week of December 2023, attributed it to a hacking group it tracks under the name  UTA0178 . There is evidence to suggest that the VPN appliance may have been compromised as early as December 3, 2023. The two vulnerabilities that have been exploited in the wild to achieve unauthenticated command execution on the ICS device are as follows - CVE-2023-46805  (CVSS score: 8.2) - An authentication bypass vulnerability in the web component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows a remote attacker to access restricted resources by bypassing control checks. CVE-2024-21887  (CVSS score: 9.1) - A command injection vulnerability in web components of Ivanti Connect Secur

A new zero-day security flaw has been discovered in Apache OfBiz, an open-source Enterprise Resource Planning (ERP) system that could be exploited to bypass authentication protections. The vulnerability, tracked as  CVE-2023-51467 , resides in the login functionality and is the result of an incomplete patch for another critical vulnerability ( CVE-2023-49070 , CVSS score: 9.8) that was released earlier this month. "The  security measures  taken to patch CVE-2023-49070 left the root issue intact and therefore the authentication bypass was still present," the SonicWall Capture Labs threat research team, which discovered the bug,  said  in a statement shared with The Hacker News. CVE-2023-49070 refers to a pre-authenticated remote code execution flaw impacting versions prior to 18.12.10 that, when successfully exploited, could allow threat actors to gain full control over the server and siphon sensitive data. It is caused due to a deprecated XML-RPC component within Apache

A critical Bluetooth security flaw could be exploited by threat actors to take control of Android, Linux, macOS and iOS devices. Tracked as  CVE-2023-45866 , the issue relates to a case of authentication bypass that enables attackers to connect to susceptible devices and inject keystrokes to achieve code execution as the victim. "Multiple Bluetooth stacks have authentication bypass vulnerabilities that permit an attacker to connect to a discoverable host without user confirmation and inject keystrokes," said security researcher  Marc Newlin , who  disclosed  the flaws to the software vendors in August 2023. Specifically, the attack deceives the target device into thinking that it's connected to a Bluetooth keyboard by taking advantage of an "unauthenticated pairing mechanism" that's defined in the Bluetooth specification. Successful exploitation of the flaw could permit an adversary in close physical proximity to connect to a vulnerable device and trans

VMware is warning of a critical and unpatched security flaw in Cloud Director that could be exploited by a malicious actor to get around authentication protections. Tracked as  CVE-2023-34060  (CVSS score: 9.8), the vulnerability impacts instances that have been upgraded to version 10.5 from an older version. "On an upgraded version of VMware Cloud Director Appliance 10.5, a malicious actor with network access to the appliance can bypass login restrictions when authenticating on port 22 (ssh) or port 5480 (appliance management console)," the company  said  in an alert. "This bypass is not present on port 443 (VCD provider and tenant login). On a new installation of VMware Cloud Director Appliance 10.5, the bypass is not present." The virtualization services company further noted that the impact is due to the fact that it utilizes a version of sssd from the underlying Photon OS that is affected by  CVE-2023-34060 .
