Class 3 attacks are often met in large corporations where the Web is the standard way (for both internal employées and "clients") to interact with the corporate data. I've seen some webapps audits where : - malicous data can be inserted via the main corporate website by anybody with a valid email - the main processing is done deep in the internal network, through the Intranet - the Intranet *must* (corporate policy) be configured as Fully Trusted in Internet Explorer, allowing the attacker to use, for example, unsigned ActiveX to hack internal machines. Not sanitizing input is bad, but storing it for later processing with different privileges is much worse ... -- Nicolas Gregoire ----- Consultant en Sécurité des Systèmes d'Information ngregoire@xxxxxxxxxxxx ------[ ExaProbe ]------ http://www.exaprobe.com/ PGP KeyID:CA61B44F FingerPrint:1CC647FF1A55664BA2D2AFDACA6A21DACA61B44F
