CVE-2022-0166 McAfee Agent uses openssl.cnf to specify the OPENSSLDIR as a subdirectory of the installation directory.

CVE-2022-0166 McAfee Agent uses openssl.cnf to specify the OPENSSLDIR as a subdirectory of the installation directory.

McAfee 6.5.5 and earlier versions are affected. McAfee Agent is a software that runs with low privileged user account (Agent user) and runs with SYSTEM account when the system is in non-managed mode. McAfee Agent provides the functionality of Remote Control allowing a remote sysadmin to execute command on the managed system. McAfee Agent also provides the capability of installing software packages, which in this case, has the potential of being exploited to install a malicious openssl.cnf file.
To exploit this vulnerability, an attacker needs to log into a system as a low privileged user. Attackers can create a low privileged user account and log into the system as a low privileged user. An attacker can then create a malicious openssl.cnf file, place it in the location specified in the openssl.cnf, and then log out of the low privileged user account. An attacker can then reboot the system to trigger the restart of McAfee Agent. When the system restarts and runs McAfee Agent with the same low privileged user account, the attacker’s malicious openssl.cnf will be loaded from the system’s location specified in the openssl.cnf file.
