What is CVE-2024-23917?

CVE-2024-23917 is a critical vulnerability in JetBrains TeamCity, a widely used continuous integration and continuous delivery (CI/CD) tool designed to help development teams automate their build, test, and deployment processes. This vulnerability allows unauthorized access through an authentication bypass, potentially enabling remote code execution (RCE). Its exploitation could lead to severe consequences for organizations, including unauthorized control over the development environment, which may result in compromised code integrity and security breaches.

Technical Details

This vulnerability exists in versions of JetBrains TeamCity prior to 2023.11.3. The technical flaw pertains to the authentication mechanism that fails to adequately restrict access, thereby allowing attackers to bypass standard authentication protocols. By exploiting this weakness, an attacker could send specially crafted requests to the TeamCity server, resulting in the execution of arbitrary code remotely. The flaw exemplifies a significant security risk, especially for organizations relying on TeamCity for managing their continuous integration processes.

Impact of the Vulnerability

  1. Unauthorized System Access: The vulnerability enables attackers to gain unauthorized access to TeamCity environments, which could allow them to manipulate builds, alter configurations, or infiltrate sensitive code repositories.

  2. Remote Code Execution: Successful exploitation leads to remote code execution, where attackers can execute malicious code on the host machine. This could facilitate further network intrusions, data exfiltration, or the deployment of additional malware.

  3. Data Breach and Compliance Risks: With acquired control, attackers can access sensitive information, including proprietary code and personal data, leading to data breaches. This exposes organizations to potential compliance violations and associated legal ramifications, as sensitive data could be improperly handled or disclosed.
