Short explanation
An authentication bypass vulnerability exists in Traccar versions 5.1 through 6.15.0 due to routing differences in path parameters. An unauthenticated attacker can gain read-only access to protected device media files.
This flaw allows attackers to bypass session and device authorization checks, exposing protected media files such as photographs, audio, and video.
What should be done?
- Follow vendor advisory recommendations
- Deploy reverse proxies that reject or rewrite semicolon path parameters
Chain of evidence and sources
Traccar 5.1 ile 6.15.0 sürümleri arasında yol parametreleri üzerinden kimlik doğrulama atlatma açığı bulunmaktadır.
Saldırganlar, cihaz benzersiz kimliği ve dosya adını bilerek korunan medya dosyalarına erişebilir.
Show the technical text from the sources
Traccar is an open source GPS tracking system. From 5.1 until 6.15.0, WebModule.java's MediaFilter Guice mapping and WebServer.java's Jetty ResourceServlet assign different routing meanings to path parameters at /api/media/*. An unauthenticated attacker who knows or guesses a device unique ID and media filename can insert a semicolon at the Servlet boundary, bypass MediaFilter's session and device authorization checks, and retrieve the protected media because Jetty still dispatches the noncanonical path to ResourceServlet. The demonstrated impact is read-only disclosure of a protected device media file; depending on the deployment and stored media, this could expose photographs, audio, video, or other uploaded files. The advisory does not establish directory listing, traversal, modification, account takeover, denial of service, or code execution. Reverse proxies that reject or rewrite semicolon path parameters may block the request. This issue is fixed in version 6.15.0.
