When the service of ABP and AES is installed in a directory writable by non-administrative users, an attacker can replace or plant a DLL with the same name as one loaded by the service. Upon service restart, the malicious DLL is loaded and executed under the LocalSystem account, resulting in unauthorized code execution with elevated privileges. This issue affects ABP and AES: from ABP 2.0 through 2.0.7.9050, from AES 1.0 through 1.0.6.8290.

The Windows service configuration of ABP and AES contains an unquoted ImagePath registry value vulnerability. This allows a local attacker to execute arbitrary code by placing a malicious executable in a predictable location such as C:\Program.exe. If the service runs with elevated privileges, exploitation results in privilege escalation to SYSTEM level. This vulnerability arises from an unquoted service path affecting systems where the executable resides in a path containing spaces. Affected products and versions include: ABP 2.0.7.6130 and earlier as well as AES 1.0.6.6133 and earlier.
