CVE-2026-54207: TeamDavid: Server-Side Request Forgery (SSRF) via 'pathname' parameter in move archive functionality
Tobit Laboratories AG TeamDavid's Webbox 's move archive functionality (“!ArcEntryMove”) accepts an arbitrary path, which can be set to network locations using UNC paths (e.g., “\\Server\Share”). The server processes these paths without validation, resulting in outbound connection attempts to attacker-controlled SMB servers. This enables au-thenticated attackers to trigger the server to authenticate to arbitrary SMB endpoints, potentially exposing NTLM authentication information (such as NTLM hashes). If outbound connections to port 445 (SMB) are permitted, attackers can use this to conduct SMB relay or credential theft attacks. Exploitation of the “pathname” parameter is possible without authentication. This issue affects TeamDavid through Rollout 524.
