MicroWorld eScan Virus Control 9.0.722.1, Anti-Virus 9.0.722.1, and Internet Security 9.0.722.1 use weak permissions (Everyone:Full Control) for their installation directory trees, which allows local users to gain privileges by replacing application files, as demonstrated by traysser.exe.

A kernel handle leak issue in ProcObsrvesx.sys 4.0.0.49 in MicroWorld Technologies Inc eScan Antivirus could allow privilege escalation for low-privileged users.
