On 7/24/07, Cisco Systems Product Security Incident Response Team <[EMAIL PROTECTED]> exposed their shame as such: > ... > Cisco Wireless LAN Controllers (WLC) contain multiple vulnerabilities > in the handling of Address Resolution Protocol (ARP) packets that could > result in a denial of service (DoS) in certain environments.
hey, that's a feature! just sit back and let aircrack-ptw go to town! uNF! > The WLC contains vulnerabilities in the processing of unicast ARP > traffic where a unicast ARP request may be flooded on the LAN links > between Wireless LAN Controllers in a mobility group. unicast == broadcast? that's some funny shit, cisco. how long you been doing this networking stuff? (ok, centralized MAC's for wifi are not old hat, but still...) > A vulnerable WLC may mishandle unicast ARP requests from a wireless > client leading to an ARP storm. In order for the vulnerability to be > exposed, two WLCs attached to the same set of Layer-2 VLANs must each > have a context for the wireless client. This can occur after a Layer-3 > (cross-subnet) roam or when guest WLAN (auto-anchor) is in use. this is almost as much fun as associating to an AP with its own MAC, then doing a DHCP. (when it works, it's hilarious!) > ... > This vulnerability is documented as CSCsj69233. > ... This vulnerability is documented > as CSCsj50374 ...

This behavior has been corrected as part of CSCsj70841. a few stones uncovered eh.. thanks for the lolz _______________________________________________ Full-Disclosure - We believe in it.
