Symantec Norton AntiVirus Corporate Edition winhlp32 file could allow elevated privileges
| nav-winhlp32-gain-privileges (10475) |  Medium Risk |
Description:
Norton AntiVirus Corporate Edition could allow a local attacker to gain elevated privileges on the system, caused by a vulnerability in the Norton help interface process. The Norton AntiVirus help interface uses the Windows winhlp32.exe file to provide help and support to the client, but uses the privileges of Norton AntiVirus Corporate Edition instead of normal winhlp32 privileges. If a local attacker with a valid user account is logged on to the affected system, the attacker may be able to exploit this vulnerability to gain full SYSTEM level privileges.
Consequences:
Gain Privileges
