Detailsinfo

A vulnerability, which was classified as very critical, was found in Tobit Laboratories TeamDavid up to Rollout 524. Affected is some unknown functionality of the component Sending Email. The manipulation of the argument pathname with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Tobit Laboratories AG TeamDavid's Webbox 's sending email, fax, SMS, etc. functionality accepts a @@INCLUDE command, 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 authenticated 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.
