Stack-based buffer overflow and out-of-bounds write vulnerability in Thales Sentinel Keys Server on Windows allows Overflow Buffers.  Sentinel Keys Server does not check the length of the first field in the input message. A local attacker may craft an input and send it to Sentinel Keys Server. It may lead to code execution as NT AUTHORITYSYSTEM enabling local privilege escalation. This issue affects Sentinel Keys Server: versions lower than 1.3.8.0.

A stack-based buffer overflow and missing authorization issue exists in the HTTP handler of the software on Windows. The server fails to validate the length of the first field in an HTTP request, allowing an unauthenticated remote attacker to send a specially crafted request. This can lead to remote code execution with NT AUTHORITYSYSTEM privileges.

Missing authentication for a critical function in the Windows Health and Optimized Experiences Service allows an authorized attacker to elevate privileges locally to SYSTEM. Low-privileged code with access to the Windows diagnostics workflow can trigger a trusted Event Tracing for Windows (ETW) event containing an attacker-controlled Lua module path. The `whesvc` service can then execute that module through WinDiag without properly validating the producer or restricting the module location.
