What happened
SolarWinds warns of critical Web Help Desk RCE auth bypass flaws after disclosing an authentication bypass and unauthenticated remote code execution vulnerability in its SolarWinds Web Help Desk IT ticketing solution. The issue allows remote attackers to execute arbitrary system commands without authenticating, rooted in improper input validation and deserialization logic in the web interface. SolarWinds released security updates on January 28, 2026 to address the flaw, urging customers to apply patches promptly to remediate the risks. The vulnerability carries a high severity score and poses significant risk, especially since Web Help Desk is commonly exposed internally in enterprise environments for ITSM and asset management functions.
Who is affected
Organizations using SolarWinds Web Help Desk are directly impacted, particularly where the application is network-accessible, with potential for unauthorized compromise of help desk servers and broader IT infrastructure.
Why CISOs should care
Unauthenticated remote code execution and authentication bypass in widely deployed IT service tools undermine asset assurance and can provide attackers with lateral movement and persistence footholds, increasing operational and incident response risk.
3 practical actions
-
Patch without delay: Apply SolarWinds Web Help Desk updates to all affected instances and confirm version compliance.
-
Restrict access: Limit network exposure of help desk systems to trusted internal segments and require strong authentication.
-
Enhance monitoring: Detect anomalous access or command execution attempts against Web Help Desk endpoints.
