Symantec VIP Access
Desktop versions prior to 2.2.2
Arbitrary DLL Execution
VIP Access Desktop UI Manager invokes DLLs from the current working folder
during startup. A malicious local user can create
specifically modified DLLs to replace the normal product DLLs required
Then, by redirecting the startup path of the VIP Access Desktop UI Manager
the user can cause the VIP Access Desktop
UI Manager to invoke the substituted DLL instead of the required product
DLL. Any specifically modified code execution
could be performed with logged-on user privileges, which is normally
user-level access in currently supported operating systems.
Ultimately, this problem is caused by a failure to properly validate
required product DLLs during start-up.
This could result in a local user being able to manipulate VIP Access
Desktop to load and execute an arbitrary DLL of the useras
choice with user-level privileges.
