CVE-2022-35508 is a critical Server-Side Request Forgery (SSRF) vulnerability affecting Proxmox Virtual Environment (PVE) and Proxmox Mail Gateway (PMG), specifically within the pve(pmg)proxy and pve(pmg)daemon HTTP request handling. An unprivileged attacker can exploit this to achieve file disclosure on the server, and in PMG, potentially escalate privileges to root if backup files exist. With a CVSS score of 9.8 (CRITICAL), this vulnerability is easily exploitable over the network with low attack complexity, leading to high impact on confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high FAUCET Risk Score of 79/100 indicates significant potential risk. The issue is addressed in pve-http-server 4.1-3.
