Package : mapserver Version : 7.6.2-1+deb11u1 CVE ID : CVE-2021-32062 CVE-2025-59431 Debian Bug : 988208

Vulnerabilities were found in mapserver, a CGI-based framework for Internet map services, which could lead to security controls bypass or SQL injection.

CVE-2021-32062

Due to a logic flaw associated with processing map parameter, it is possible to specify an arbitrary mapfile that bypasses the `MS_MAP_NO_PATH` and `MS_MAP_PATTERN` security control checks.

CVE-2025-59431

Alwin Warringa discovered that XML Filter Query directive `PropertyName` is vulnerably to Boolean-based SQL injection, allowing to manipulate backend database queries via crafted XML Filter Query directives.

For Debian 11 bullseye, these problems have been fixed in version 7.6.2-1+deb11u1.

We recommend that you upgrade your mapserver packages.
