4.6
CVSS v3.1
Official Description
RapDrv.sys in BlackICE PC Protection 3.6.cpn, cpj, cpiE, and possibly 3.6 and earlier, allows local users to cause a denial of service (crash) via a NULL third argument to the NtOpenSection API function. NOTE: it was later reported that 3.6.cqn is also affected.
Technical Analysis
CVE-2006-4541 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-2006-4541. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
