Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A privilege escalation vulnerability in the McAfee Agent prior to 5.7.5. McAfee Agent uses openssl.cnf during the build process to specify the OPENSSLDIR variable as a subdirectory within the installation directory. A low privilege user could have created subdirectories and executed arbitrary code with SYSTEM privileges by creating the appropriate pathway to the specifically created malicious openssl.cnf file.
