Description
A local user can escalate their privileges through a DLL hijacking attack against the installer. The installer writes the file rm.exe to C:WindowsTemp and then executes it. The rm.exe process attempts to load several DLLs from its current directory. Non-admin users can write to this folder, allowing an attacker to create a malicious C:WindowsTempOLEACC.dll file. When an admin runs the installer, rm.exe will execute the attacker's DLL in an elevated security context.
