This is a bit old (2007) but it shows this kind of bug perfectly well. http://securitytracker.com/id/1018588
So I can imagine one scenario in which DLL hijacking would make sense - if the developers neglected to properly set the directory permissions and it got reported as a vuln, the patch *could* have been to properly set the permissions on *files* and forget to set them on the directory. It'd be an extremely stupid way to patch. Then again, it's an extremely stupid bug to begin with, so... :) On Mon, Sep 26, 2011 at 3:36 AM, Thor (Hammer of God) <t...@hammerofgod.com>wrote: > You'd have to be admin to install as a service, and the service would > obviously need to then be running as local system to be of benefit (beyond > what a normal user could do anyway) AND the installer would have to grant a > normal user rights to overwrite it. > > Certainly possible, but the developer would have to go out of their way > to screw that up.
