Masa CMS is an open source Enterprise Content Management platform. Masa CMS versions prior to 7.2.8, 7.3.13, and 7.4.6 are vulnerable to remote code execution. The vulnerability exists in the addParam function, which accepts user input via the criteria parameter. This input is subsequently evaluated by setDynamicContent, allowing an unauthenticated attacker to execute arbitrary code via the m tag. The vulnerability is patched in versions 7.2.8, 7.3.13, and 7.4.6.
