CVE-2024-28986

critical

Description

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.
