Detailsinfo

A vulnerability, which was classified as problematic, was found in SmarterTools SmarterMail. This affects some unknown processing of the component Service. The manipulation with an unknown input leads to a name resolution vulnerability. CWE is classifying the issue as CWE-706. The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. This is going to have an impact on confidentiality. The summary by CVE is:

SmarterTools SmarterMail versions prior to build 9518 contain an unauthenticated path coercion vulnerability in the background-of-the-day preview endpoint. The application base64-decodes attacker-supplied input and uses it as a filesystem path without validation. On Windows systems, this allows UNC paths to be resolved, causing the SmarterMail service to initiate outbound SMB authentication attempts to attacker-controlled hosts. This can be abused for credential coercion, NTLM relay attacks, and unauthorized network authentication.

The weakness was published by Cale Black. It is possible to read the advisory at smartertools.com. This vulnerability is uniquely identified as CVE-2026-25067 since 01/28/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

Upgrading to version 100.0.9518 eliminates this vulnerability.
