Senserva AI Opinion for CVE-2024-28987

SolarWinds Web Help Desk ships with a hardcoded credential that lets remote unauthenticated users access internal functionality and modify data. Help desk platforms store tickets full of passwords, network details, and reset workflows, which is what makes the 93% EPSS score and 2024-10-15 KEV listing alarming rather than academic. No exploit development is needed, just knowledge of the baked-in credential.

Do this: Update Web Help Desk immediately and audit recent ticket and configuration changes for tampering.
