Hi,

http://www.cisco.com/warp/public/707/cisco-sa-20040827-telnet.shtml

---- A specifically crafted Transmission Control Protocol (TCP) connection to a telnet or reverse telnet port of a Cisco device running Internetwork Operating System (IOS)(r) may block further telnet, reverse telnet, Remote Shell (RSH), Secure Shell (SSH), and in some cases Hypertext Transport Protocol (HTTP) access to the Cisco device. Telnet, reverse telnet, RSH and SSH sessions established prior to exploitation are not affected. ----

dus.. ;)

Zucht.. Ik dacht al, het was al weer even geleden dat er weer een Cisco bugje voorbij kwam.. ;-)) Nils
