SourceCVE-2024-23917

JetBrains TeamCity, a popular continuous integration and delivery server, had a critical vulnerability that could allow remote code execution without authentication. The vulnerability with CVE identifier CVE-2024-23917 and CVSS score of 9.8 affected versions before 2023.11.3.

An attacker could potentially bypass authentication and log in as any user to TeamCity due to this issue. This would give them control over the server and ability to execute code remotely. Since TeamCity is often used to build and deploy applications, this gives the attacker power over software development and deployment pipelines.

It is important that all TeamCity users upgrade to the latest version 2023.11.3 or later immediately to patch this vulnerability. Administrators should also consider changing any default or weak passwords. Enabling multi-factor authentication can provide an extra layer of protection where supported.

Staying on top of software updates is critical for security. This vulnerability shows why applying patches promptly is so important, especially for tools like CI/CD servers that are interfacing with code and deployments. By taking action now to upgrade TeamCity, users can protect their systems and development workflows from this remote code execution vulnerability.
