Authenticated memory disclosure via service out-of-bounds read
Published Jan 27, 2026 · Updated Jan 27, 2026
Information disclosure in Beckhoff Device Manager allows remote authenticated users to read privileged process memory via its web service. A crafted message in UI-to-service communication makes an undisclosed service process read outside its intended buffer and return adjacent memory. Administrative access rights are required, ASLR-dependent conditions limit reliability, and the user cannot choose which sensitive data appears.
