Vulnerability from fkie_nvd - Published: 2025-04-15 19:16 - Updated: 2025-04-16 13:25
Severity ?
8.3 (High) - CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N
Summary
Collabora Online is a collaborative online office suite based on LibreOffice technology. In versions prior to 24.04.12.4, 23.05.19, and 22.05.25, there is a path traversal flaw in handling the CheckFileInfo BaseFileName field returned from WOPI servers. This allows for a file to be written anywhere the uid running Collabora Online can write, if such a response was supplied by a malicious WOPI server. By combining this flaw with a Time of Check, Time of Use DNS lookup issue with a WOPI server address under attacker control, it is possible to present such a response to be processed by a Collabora Online instance. This issue has been patched in versions 24.04.13.1, 23.05.19, and 22.05.25.

En versiones anteriores a la 24.04.12.4, la 23.05.19 y la 22.05.25, exist\u00eda una falla de recorrido de ruta al gestionar el campo CheckFileInfo BaseFileName devuelto por los servidores WOPI. Esto permit\u00eda escribir un archivo en cualquier lugar donde el uid que ejecuta Collabora Online pudiera escribir, si dicha respuesta proven\u00eda de un servidor WOPI malicioso. Al combinar esta falla con un problema de b\u00fasqueda DNS en el tiempo de verificaci\u00f3n y el tiempo de uso con una direcci\u00f3n de servidor WOPI controlada por un atacante, es posible presentar dicha respuesta para que sea procesada por una instancia de Collabora Online. Este problema se ha corregido en las versiones 24.04.13.1, la 23.05.19 y la 22.05.25."
