Authenticated privilege gain via undisclosed WebAPI vectors
Published Dec 4, 2025 · Updated Dec 4, 2025
Improper control of dynamic code resources in Synology DSM and DSMUC allows remote authenticated users to gain privileges through WebAPI. Synology identifies the WebAPI component but withholds the affected function, attacker-controlled input, and exact operation on that input. A valid account and network access are required, and the vendor assessment limits the demonstrated consequence to unauthorized integrity changes.
