Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The mingSoft MCMS package net.mingsoft:ms-mcms, versions up to and including 6.1.1, does not properly restrict file uploads in its template archive handling. A remote attacker can use this to upload arbitrary files, and a public exploit exists. The source gives few details on the exact impact. No fixed version is listed, so check with the vendor for a patch or apply access restrictions to the template upload function.
