CVSS v3.1

Official Description

The PGPwded device driver (aka PGPwded.sys) in PGP Corporation PGP Desktop 9.0.6 build 6060 and 9.9.0 build 397 allows local users to cause a denial of service (system crash) and possibly gain privileges via a certain METHOD_BUFFERED IOCTL request that overwrites portions of memory, related to a "Driver Collapse." NOTE: some of these details are obtained from third party information.

Technical Analysis

CVE-2008-5731 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2008-5731. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
