Under Active Attack

Executive Summary

In September 2025, a critical vulnerability (CVE-2025-26399) was identified in SolarWinds Web Help Desk, allowing unauthenticated remote attackers to execute arbitrary code on affected systems. This flaw, rooted in insecure deserialization within the AjaxProxy component, enables attackers to run commands on the host machine without authentication. Despite previous patches for related vulnerabilities (CVE-2024-28986 and CVE-2024-28988), this issue persisted, leading to active exploitation in the wild. Organizations using versions up to 12.8.7 are at significant risk and should apply the latest hotfix immediately. The recurrence of such vulnerabilities underscores the importance of comprehensive security reviews and prompt patch management. As attackers increasingly exploit deserialization flaws, organizations must prioritize securing their software supply chains and implementing robust monitoring to detect and respond to such threats promptly.

Why This Matters Now

The active exploitation of CVE-2025-26399 highlights the urgency for organizations to apply the latest patches to prevent potential system compromises and data breaches.

Frequently Asked Questions

SolarWinds Web Help Desk versions up to and including 12.8.7 are affected by this vulnerability.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Aviatrix Zero Trust CNSF is pertinent to this incident as it could have limited the attacker's ability to move laterally and exfiltrate data by enforcing strict segmentation and identity-aware policies. This would likely have reduced the attacker's reach and minimized the blast radius within the network.

Initial Compromise

Control: Cloud Native Security Fabric (CNSF)

Mitigation: While initial exploitation may still occur, Aviatrix CNSF would likely limit the attacker's ability to escalate privileges or move laterally by enforcing strict segmentation and identity-aware policies.

Privilege Escalation

Control: Zero Trust Segmentation

Mitigation: Aviatrix Zero Trust Segmentation would likely limit the attacker's ability to escalate privileges by enforcing least-privilege access controls and isolating workloads.

Lateral Movement

Control: East-West Traffic Security

Mitigation: Aviatrix East-West Traffic Security would likely limit the attacker's lateral movement by enforcing strict segmentation and monitoring east-west traffic.

Command & Control

Control: Multicloud Visibility & Control

Mitigation: Aviatrix Multicloud Visibility & Control would likely limit the attacker's ability to establish command and control channels by providing real-time monitoring and control over network traffic.

Exfiltration

Control: Egress Security & Policy Enforcement

Mitigation: Aviatrix Egress Security & Policy Enforcement would likely limit data exfiltration by controlling and monitoring outbound traffic.

Impact (Mitigations)

Aviatrix CNSF would likely reduce the scope of potential service disruptions or ransomware deployment by limiting the attacker's ability to propagate within the network.

Data Exposure

Potential exposure of sensitive IT service management data, including user credentials and asset information.

Recommended Actions

  • • Implement Zero Trust Segmentation to restrict lateral movement and limit the attacker's ability to access critical systems.
  • • Deploy Inline IPS (Suricata) to detect and prevent exploitation attempts targeting known vulnerabilities.
  • • Utilize Egress Security & Policy Enforcement to monitor and control outbound traffic, preventing unauthorized data exfiltration.
  • • Enhance Threat Detection & Anomaly Response capabilities to identify and respond to suspicious activities promptly.
  • • Ensure all systems are updated with the latest security patches to mitigate known vulnerabilities.
