By analyzing the password-based authentication for unloading the Kaspersky Endpoint Security for Windows protection, the SySS GmbH found out, that the password comparison is done within the process avp.exe, which runs or can be run in the context of the current Windows user, who can also be a standard, limited user. This fact allows a further analysis and the manipulation of the password comparison during runtime without administrative privileges, as every user is able to debug and manipulate the processes running with her user privileges. In order to bypass the password-based authentication to deactivate the protection of Kaspersky Endpoint Security for Windows in an unauthorized manner, an attacker only has to patch this password comparison, so that it always returns true, for example by comparing the correct unload password with itself or by modifying the program control flow.
