CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:10 mapserver to version 5.2.2-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mapserver package and not the mapserver package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The msLoadQuery function in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 allows remote attackers to determine the existence of arbitrary files via a full pathname in the queryfile parameter, which triggers different error messages depending on whether this pathname exists.
