Product Link: http://www.pctools.com/anti-virus/ ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a security issue in PC Tools AntiVirus, which can be exploited by malicious, local users to gain escalated privileges. The problem is caused due to the application setting insecure default permissions (grants "Everyone" group "Full Control") on the "PC Tools AntiVirus" directory and all child objects. This can be exploited to remove, manipulate, and replace any of the application's files. Successful exploitation allows execution of arbitrary commands with SYSTEM privileges. ====================================================================== 5) Solution Grant only trusted users access to affected systems. Set proper permissions on the directory and all child objects (this may impact the functionality). ====================================================================== 6) Time Table 19/07/2006 - Vendor notified. 02/08/2006 - Vendor notified again. 03/08/2006 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2006-3114 for the vulnerabilities. ====================================================================== 9) About Secunia Secunia collects, validates, assesses, and writes advisories regarding all the latest software vulnerabilities disclosed to the public.
