Cisco’s PIX firewall appliances are used by a lot of corporate users and this unpatched loophole could allow outside crackers to gain access and wreak havoc on corporate networks.
Techworld has this to report:
On the final slide of his presentation at the Black Hat show on VoIP security, Hendrik Scholz, a developer with Freenet Cityline disclosed a technique for bypassing the firewalls, according to an audio recording of the talk obtained by IDG News. And Scholz himself declined to comment further on the exploit, saying he was waiting for Cisco to address the matter. "If you are interested in details regarding 'the last slide' all I can tell you right now is that Cisco is working to get it fixed," he said via e-mail.
