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: 2.2


The remote web application server is affected by an information disclosure vulnerability


The IBM WebSphere Application Server running on the remote host is version 6.1.0.x through, 7.0.0.x prior to, 8.0.0.x prior to, or 8.5.0.x prior to It is, therefore, affected by an information disclosure vulnerability due to a failure to properly convey a DHE_EXPORT ciphersuite choice (LogJam). A remote, unauthenticated attacker can exploit this, using man in the middle techniques, to force a downgrade to 512-bit export- grade cipher in order to recover the session key and modify the contents of the traffic.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to IBM WebSphere Application Server,,, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix and update recommended in the vendor advisory.
