JetBrains TeamCity is a powerful Continuous Integration and Continuous Deployment (CI/CD) server used by developers and organizations to automate build, test, and release processes. It is widely adopted by software development teams for its flexibility and integration capabilities with various tools and platforms. The platform supports a variety of programming languages and development workflows, making it a versatile choice for teams of all sizes. TeamCity's user-friendly interface and robust feature set streamline the development pipeline, enhancing productivity and collaboration among team members. Organizations use TeamCity to ensure efficient and reliable software delivery.

The vulnerability in JetBrains TeamCity before version 2023.11.3 allows an authentication bypass, which can lead to remote code execution (RCE). This critical flaw enables attackers to gain unauthorized access to the system without proper credentials. Exploiting this vulnerability can compromise the integrity, confidentiality, and availability of the affected systems. It is crucial for administrators to update their installations to mitigate the risks associated with this flaw.

The authentication bypass vulnerability in JetBrains TeamCity is due to improper handling of user authentication tokens. Attackers can exploit this by sending specially crafted requests to the endpoint /app/rest/users/id:1/tokens/{{randstr}};.jsp?jsp_precompile=true. If successful, they receive a valid authentication token in the response. Using this token, attackers can access the /app/rest/server endpoint and potentially execute remote commands on the server. The flaw resides in the way TeamCity processes and validates authentication tokens, allowing unauthorized access.

Exploitation of this vulnerability can have severe consequences, including unauthorized access to sensitive data, execution of arbitrary commands on the server, and complete system compromise. Attackers could potentially manipulate or steal data, disrupt services, and escalate their privileges within the network. This can lead to data breaches, financial losses, and reputational damage to the affected organization.
