CVE-2023-25162

Public Exploit
Nextcloud Server vulnerable to SSRF via filter bypass due to lax checking on IPs

Description

Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. Nextcloud Server prior to 24.0.8 and 23.0.12 and Nextcloud Enterprise server prior to 24.0.8 and 23.0.12 are vulnerable to server-side request forgery (SSRF).

Nextcloud Server 24.0.8 and 23.0.2 and Nextcloud Enterprise Server 24.0.8 and 23.0.12 contain a patch for this issue. No known workarounds are available.
