BlackICE pamversion.dll insecure permission
| blackice-pamversion-insecure-permission (28171) |  High Risk |
Description:
BlackICE could allow a local attacker to gain elevated privileges, caused by insecure permissions on the pamversion.dll. A local attacker could replace the pamversion.dll with a malicious file that would be loaded once the BlackICE service is started. A local attacker could exploit this vulnerability to gain elevated privileges.
Platforms Affected:
- IBM, ISS BlackICE PC Protection 3.6
- IBM, ISS Proventia Desktop 8.0
- IBM, ISS Proventia Server IPS for Windows
- IBM, ISS RealSecure Desktop 7.0
Remedy:
For Proventia Desktop 8.0 and Proventia Server:
Ensure that Agent Protection feature is enabled and "protect file and services" is selected in the policy.
For BlackICE 3.6 and RealSecure Desktop 7.0:
Mitigate the issue via Active Directory or another enterprise IT configuration management system. Change the permissions on the BlackICE files so that they can only be written by the Administrator.
Consequences:
Gain Privileges

- CVE-2006-3999: ISS BlackICE PC Protection 3.6.cpj, 3.6.cpiE, and possibly earlier versions do not properly monitor the integrity of the pamversion.dll BlackICE library, which allows local users to subvert BlackICE by replacing pamversion.dll. NOTE: in most cases, the attack would not cross privilege boundaries because replacing pamversion.dll requires administrative privileges. However, this issue is a vulnerability because BlackICE is intended to protect against certain rogue privileged actions.
