Remote code execution through JBossMQ HTTPServerILServlet deserialization

IdentifiersCVE-2017-7504CWE-502· Deserialization of Untrusted Data

CVE-2017-7504 is an insecure Java deserialization vulnerability in HTTPServerILServlet within the JBossMQ JMS over HTTP Invocation Layer. This component, enabled by default in Red Hat JBoss Application Server 4.x and earlier, does not restrict the classes it deserializes. Remote attackers can submit crafted serialized data to execute arbitrary code. Gold Melody has been linked to exploitation of this vulnerability.

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 remote attackers to execute arbitrary code on the affected server. Specific execution privileges and resulting confidentiality or availability impacts are not established.

Mitigation

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

Disable the JMS over HTTP Invocation Layer and prevent exposure of the vulnerable servlet to untrusted networks. Restrict access to the affected HTTP endpoint through network segmentation, reverse-proxy filtering, firewall policy, or application-server configuration so that only trusted administrative or internal systems can reach it. As a defense-in-depth measure, reduce or eliminate deserialization of untrusted data and monitor for exploitation attempts targeting Java deserialization in JBoss services.

Remediation

Patch, then assume compromise.

Upgrade Red Hat JBoss Application Server to a fixed release that disables or corrects the unsafe deserialization behavior in the JBossMQ HTTP invocation layer. If an official vendor patch or supported upgrade path is available for the deployed version, apply it promptly. Where JBossMQ is no longer required, remove or disable the vulnerable JMS over HTTP Invocation Layer component entirely as part of remediation.
