McAfee Agent contains a privilege escalation vulnerability due to the use of an
OPENSSLDIR variable that specifies a location where an unprivileged Windows user may be able to place files.
McAfee Agent, which comes with various McAfee products such as McAfee Endpoint Security, includes an OpenSSL component that specifies an
OPENSSLDIR variable as a subdirectory that my be controllable by an unprivileged user on Windows. McAfee Agent contains a privileged service that uses this OpenSSL component. A user who can place a specially-crafted
openssl.cnf file at an appropriate path may be able to achieve arbitrary code execution with SYSTEM privileges.
By placing a specially-crafted
openssl.cnf in a location used by McAfee Agent, an unprivileged user may be able to execute arbitrary code with SYSTEM privileges on a Windows system with the vulnerable McAfee Agent software installed.
