CVE-2024-52521

Nextcloud Server is a self hosted personal cloud system. MD5 hashes were used to check background jobs for their uniqueness. This increased the chances of a background job with arguments falsely being identified as already existing and not be queued for execution. By changing the Hash to SHA256 the probability was heavily decreased. It is recommended that the Nextcloud Server is upgraded to 28.0.10, 29.0.7 or 30.0.0.

Nextcloud Server es un sistema de nube personal alojado por uno mismo. Se utilizaron hashes MD5 para comprobar la unicidad de los trabajos en segundo plano. Esto aumentó las posibilidades de que un trabajo en segundo plano con argumentos se identificara erróneamente como ya existente y no se pusiera en cola para su ejecución. Al cambiar el hash a SHA256, la probabilidad se redujo considerablemente. Se recomienda que el servidor Nextcloud se actualice a 28.0.10, 29.0.7 o 30.0.0.
