CVE-2024-27198 Scanner Detail

JetBrains TeamCity is a continuous integration and continuous delivery server developed by JetBrains. It is widely used by software development teams to automate code building, testing, and deployment processes. TeamCity supports a variety of programming languages and frameworks, making it a versatile tool for integrating with numerous development environments. The platform is designed to improve the efficiency of software development workflows, enabling teams to release software faster and with higher quality. TeamCity is utilized by organizations ranging from small startups to large enterprises for its ability to facilitate complex builds and deployments.

CVE-2024-27198 describes a critical authentication bypass vulnerability in JetBrains TeamCity versions before 2023.11.4. This security flaw allows an attacker to perform actions with administrative privileges without the need for valid credentials. The vulnerability can be exploited to gain unauthorized access to the TeamCity server, potentially leading to sensitive information disclosure, alteration of build configurations, and execution of malicious code. The high CVSS score of 9.8 reflects the severity of this vulnerability, underlining the significant risk it poses to affected systems.

The authentication bypass vulnerability is triggered by a flaw in how TeamCity handles certain requests. An attacker can exploit this by crafting a malicious request that bypasses the normal authentication process, granting them access to the TeamCity server's administrative functions. This can include actions such as viewing and modifying build configurations, accessing build logs, and executing arbitrary code on the server. The exploitation method involves sending a specially crafted request to a vulnerable endpoint, highlighting the importance of proper input validation and authentication checks in web applications.

If successfully exploited, CVE-2024-27198 could have several detrimental effects on an organization. Attackers could gain complete control over the TeamCity server, leading to data theft, alteration or deletion of build configurations, unauthorized access to source code, and the potential introduction of backdoors or other malicious code into software builds. The breach of a continuous integration/continuous delivery (CI/CD) server like TeamCity could lead to a wide-ranging impact on the software development lifecycle, affecting the integrity and security of the software being developed and deployed.
