MEDIUMPre-NVD 6.36.3—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 79% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Tobit Laboratories AG TeamDavid's Webbox 's link storing functionality (//ServerClient_celink.htm) accepts a “pathname” parameter, 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.
