SAP NetWeaver Invoker Servlet Unauthenticated Remote Code Execution

IdentifiersCVE-2010-5326CWE-306· Missing Authentication for…

CVE-2010-5326 affects the Invoker Servlet on SAP NetWeaver Application Server Java platforms, possibly before version 7.3. The servlet does not require authentication, allowing a remote attacker to invoke functionality over HTTP or HTTPS without prior login. According to the provided content, this exposure enables arbitrary code execution and was exploited in the wild between 2013 and 2016, including in activity referred to as a "Detour" attack. The core issue is an authentication bypass on a remotely reachable servlet that exposes dangerous server-side invocation capability.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an unauthenticated remote attacker to execute arbitrary code on the SAP NetWeaver AS Java host. This can provide full compromise of the affected application server, including deployment of web shells or malicious applications, execution of system commands, persistence, credential theft, and use of the server as an initial access point for broader lateral movement within the environment.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, disable the Invoker Servlet if it is not required, or restrict access to it through strong authentication and network-layer controls. Limit HTTP/HTTPS exposure of SAP NetWeaver AS Java systems to trusted management networks, place the service behind filtering or reverse proxy controls, and monitor for suspicious requests to servlet endpoints, unexpected code execution, and unauthorized application deployment. Conduct threat hunting for persistence mechanisms such as web shells and rogue WAR files.

Remediation

Patch, then assume compromise.

Upgrade SAP NetWeaver Application Server Java to a fixed release that removes or properly restricts unauthenticated access to the Invoker Servlet; the provided content indicates affected platforms are possibly before 7.3. If vendor fixes are available, apply the relevant SAP security updates and verify that the Invoker Servlet is disabled or access-controlled. Review deployed applications and server logs for evidence of prior exploitation, especially unauthorized servlet invocation, malicious WAR deployment, or web shell placement.
