Executable installers are vulnerable^WEVIL (case 15): F-SecureOnlineScanner.exe allows arbitrary (remote) code execution and escalation of privilege

Posted by Stefan Kanthak on Dec 23

Hi @ll,

F-Secure’s online virus scanner F-SecureOnlineScanner.exe, available
via <https://www.f-secure.com/en/web/home_global/online-scanner>,
loads and executes several rogue/bogus DLLs (UXTheme.dll, HNetCfg.dll,
RASAdHlp.dll, SetupAPI.dll, ClbCatQ.dll, XPSP2Res.dll, CryptNet.dll,
OLEAcc.dll etc.) eventually found in the directory it is started from
(the “application directory”).

For software downloaded with a web browser…
