New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 7.4


The remote WebSphere Application Server is affected by a remote code execution vulnerability.


The remote IBM WebSphere Application Server is affected by a remote code execution vulnerability due to unsafe deserialize calls of unauthenticated Java objects to the Apache Commons Collections (ACC) library. An unauthenticated, remote attacker can exploit this, by sending a crafted SOAP request, to execute arbitrary code on the target host.


Apply the appropriate interim fix per the vendor advisory.
Alternatively, ensure that all exposed ports used by the WebSphere Application Server are firewalled from any public networks.
