CVE-2024-23917Public exploitNetwork attack vector

Unauthenticated RCE via JSP precompilation path confusion

Published Feb 6, 2024 · Updated Aug 1, 2024

Authentication bypass in JetBrains TeamCity On-Premises 2017.1 through 2023.11.2 allows remote attackers to gain administrative control via HTTP(S). The request interceptor treats a semicolon-suffixed JSP path with jsp_precompile as precompilation and skips authorization checks. Unauthenticated HTTP(S) reachability is sufficient, and administrative control enables remote code execution on the server.
