The vulnerability identified as CVE-2024-47161 represents a critical security flaw in JetBrains TeamCity versions prior to 2024.07.3 that exposes passwords through the Sonar runner REST API. This issue falls under the category of information disclosure vulnerabilities and specifically relates to improper handling of authentication credentials within the application's API endpoints. The flaw enables unauthorized access to sensitive authentication data that should remain protected from external exposure.
The technical implementation of this vulnerability stems from insufficient input validation and output sanitization within the Sonar runner REST API interface. When TeamCity processes requests through this API endpoint, it fails to properly sanitize or restrict access to password information that may be included in the request parameters or response payloads. This creates an attack surface where malicious actors can potentially intercept or extract password credentials during legitimate API interactions. The vulnerability is particularly concerning as it affects the core authentication mechanisms that protect enterprise development environments and continuous integration systems.
From an operational impact perspective, this vulnerability poses significant risks to organizations utilizing JetBrains TeamCity for their CI/CD pipelines. The exposure of passwords through the Sonar runner REST API could lead to unauthorized access to source code repositories, build servers, and other critical infrastructure components that rely on TeamCity for automated deployment processes. Security teams face increased risk of privilege escalation attacks, unauthorized code modifications, and potential data breaches that could compromise entire development workflows. The vulnerability also impacts compliance requirements for organizations that must maintain strict controls over authentication credentials and access management.
Organizations should immediately upgrade to JetBrains TeamCity version 2024.07.3 or later to address this vulnerability. Additionally, administrators should implement network-level restrictions to limit access to the Sonar runner REST API endpoints and conduct thorough audits of existing API access controls. The vulnerability aligns with CWE-200 (Information Exposure) and may be categorized under ATT&CK technique T1566 (Phishing) when exploited through API-based credential harvesting. Security monitoring should be enhanced to detect unusual API access patterns that might indicate exploitation attempts, and all affected systems should undergo comprehensive credential rotation procedures to mitigate potential compromise risks.
