SolarWinds Web Help Desk Deserialization of Untrusted Data Vulnerability
Published Aug 13, 2024 · corrected/updated Jun 17, 2026 · SolarWinds Web Help Desk · evidence confidence very high
SolarWinds Web Help Desk was found to be susceptible to a Java Deserialization Remote Code Execution vulnerability that, if exploited, would allow an attacker to run commands on the host machine. While it was reported as an unauthenticated vulnerability, SolarWinds has been unable to reproduce it without authentication after thorough testing. However, out of an abundance of caution, we recommend all Web Help Desk customers apply the patch, which is now available.
