Threats Tagged 'cve-2026-54207'

CVE-2026-54207 is a vulnerability in Tobit Laboratories AG TeamDavid's Webbox move archive functionality that improperly validates input paths. It allows unauthenticated attackers to specify arbitrary UNC network paths, causing the server to initiate outbound SMB connections to attacker-controlled servers. This can lead to exposure of NTLM authentication information and enable SMB relay or credential theft attacks. The vulnerability affects versions before Rollout 528, after which the vulnerable functionality is disabled by default.

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 before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.
