6DescriptionCVE.org
An issue in /cgi-bin/wwwugw.cgi of MBS-Solutions X-Serie Gateway firmware V6_00_05 allows a remote authenticated user with the low-privileged Standard role to invoke hidden network diagnostic methods (ugw-ping, ugw-traceroute) that are not exposed in the web UI, allowing attackers to obtain sensitive information.
AnalysisAI
Improper authorization in MBS-Solutions X-Serie Gateway firmware V6_00_05 permits authenticated Standard-role users to directly invoke undocumented CGI methods (ugw-ping, ugw-traceroute) via /cgi-bin/wwwugw.cgi that are intentionally hidden from the web UI. Exploitation leaks sensitive network topology data - hop paths, internal IP ranges, and reachability information - from a device positioned as a gateway, making the disclosure operationally significant. …
