Title

TeamDavid: Server-Side Request Forgery (SSRF) via 'pathnameroot' parameter in search functionality

Summary

Tobit Laboratories AG TeamDavid's Webbox 's search functionality accepts a “pathnameroot” 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 unauthenticated 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 “pathnameroot” 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.

Severity

GHSA-5G7H-MGC9-867W

Vulnerability from github – Published: 2026-08-07 12:31 – Updated: 2026-09-07 15:33

Details

Tobit Laboratories AG TeamDavid's Webbox 's search functionality accepts a “pathnameroot” 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 unauthenticated 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 “pathnameroot” parameter is possible without authentication.

This issue affects TeamDavid through Rollout 524.

  "details": "Tobit Laboratories AG TeamDavid\u0027s Webbox \u0027s search functionality accepts a \u201cpathnameroot\u201d \nparameter, which can be set to network locations using UNC paths (e.g., \n\u201c\\\\Server\\Share\u201d). The server processes these paths without validation, \nresulting in outbound connection attempts to attacker-controlled SMB \nservers. This enables unauthenticated attackers to trigger the server to\n authenticate to arbitrary SMB endpoints, potentially exposing NTLM \nauthentication information (such as NTLM hashes). If outbound \nconnections to port 445 (SMB) are permitted, attackers can use this to \nconduct SMB relay or credential theft attacks. Exploitation of the \n\u201cpathnameroot\u201d parameter is possible without authentication.\n\nThis issue affects TeamDavid through Rollout 524.",

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
