CVE-2025-62724

Open OnDemand is an open-source HPC portal. Prior to versions 4.0.8 and 3.1.16, users can craft a "Time of Check to Time of Use" (TOCTOU) attack when downloading zip files to access files outside of the OOD_ALLOWLIST. This vulnerability impacts sites that use the file browser allowlists in all current versions of OOD. However, files accessed are still protected by the UNIX permissions. Open OnDemand versions 4.0.8 and 3.1.16 have been patched for this vulnerability.

Summary		(es) Open OnDemand es un portal HPC de código abierto. Versiones anteriores a la 4.0.8 y 3.1.16, los usuarios pueden elaborar un ataque de “Tiempo de Verificación a Tiempo de Uso” (TOCTOU) al descargar archivos zip para acceder a archivos fuera de la OOD_ALLOWLIST. Esta vulnerabilidad afecta a los sitios que utilizan las listas de permitidos del navegador de archivos en todas las versiones actuales de OOD. Sin embargo, los archivos a los que se accede siguen estando protegidos por los permisos de UNIX. Las versiones 4.0.8 y 3.1.16 de Open OnDemand han sido parcheadas para esta vulnerabilidad.
