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 t...

JetBrains is alerting customers of a critical security flaw in its TeamCity On-Premises continuous integration and continuous deployment (CI/CD) software that could be exploited by threat actors to take over susceptible instances. The vulnerability, tracked as  CVE-2024-23917 , carries a CVSS rating of 9.8 out of 10, indicative of its severity. "The vulnerability 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  said . The issue impacts all TeamCity On-Premises versions from 2017.1 through 2023.11.2. It has been addressed in version 2023.11.3. An unnamed external security researcher has been credited with discovering and reporting the flaw on January 19, 2024. Users who are unable to update their servers to version 2023.11.3 can alternately download a security patch plugin to apply fixes for the flaw. "If your server is publicly acce...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...

A critical security vulnerability in the JetBrains TeamCity continuous integration and continuous deployment (CI/CD) software could be exploited by unauthenticated attackers to achieve remote code execution on affected systems. The flaw, tracked as  CVE-2023-42793 , carries a CVSS score of 9.8 and has been addressed in  TeamCity version 2023.05.4  following responsible disclosure on September 6, 2023. "Attackers could leverage this access to steal source code, service secrets, and private keys, take control over attached build agents, and poison build artifacts," Sonar security researcher Stefan Schiller  said  in a report last week. Successful exploitation of the bug could also permit threat actors to access the build pipelines and inject arbitrary code, leading to an integrity breach and supply chain compromise. It's worth noting that the shortcoming only affects on-premise versions of the JetBrains software. The TeamCity Cloud version has already been u...
