CVSS: 4.6EPSS: 0%CPEs: 3EXPL: 0CVE-2024-52523 – Nextcloud Server Custom defined credentials of external storages are sent back to the frontend
https://notcve.org/view.php?id=CVE-2024-52523
Nextcloud Server is a self hosted personal cloud system. After setting up a user or administrator defined external storage with fixed credentials, the API returns them and adds them into the frontend again, allowing to read them in plain text when an attacker already has access to an active session of a user. It is recommended that the Nextcloud Server is upgraded to 28.0.12, 29.0.9 or 30.0.2 and Nextcloud Enterprise Server is upgraded to 25.0.13.14, 26.0.13.10, 27.1.11.10, 28.0.12, 29.0.9 or 30.0.2. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-42w6-r45m-9w9j https://github.com/nextcloud/server/commit/8a13f284765bd4606984e7d925c32ae6e82b8a27 https://github.com/nextcloud/server/pull/49009 • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2024-52525
Nextcloud Server is a self hosted personal cloud system. Under certain conditions the password of a user was stored unencrypted in the session data. The session data is encrypted before being saved in the session storage (Redis or disk), but it would allow a malicious process that gains access to the memory of the PHP process, to get access to the cleartext password of the user. It is recommended that the Nextcloud Server is upgraded to 28.0.12, 29.0.9 or 30.0.2. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-w7v5-mgxm-v6gm https://github.com/nextcloud/server/commit/d25a0a2896a2a981939cacb8ee0d555feef22b3b https://github.com/nextcloud/server/pull/48915 • CWE-312: Cleartext Storage of Sensitive Information •
