Original NVD Description

Quick Heal AntiVirus Plus 2009 10.00 SP1 and Quick Heal Total Security 2009 10.00 SP1 use weak permissions (Everyone: Full Control) for the product files, which allows local users to gain privileges by replacing executables with Trojan horse programs, as demonstrated by replacing quhlpsvc.exe.
