Vulnerability from variot
The PPTP ALG implementation in Cisco IOS XE 3.9 before 3.9.2S on 1000 ASR devices allows remote attackers to cause a denial of service (device reload) by sending many PPTP packets over NAT, aka Bug ID CSCuh19936. Vendors have confirmed this vulnerability Bug ID CSCuh19936 It is released as.By a third party NAT A large amount via PPTP Service interruption due to packet transmission ( Device reload ) There is a possibility of being put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. After successful use, the system can be overloaded. Successful exploits may allow an attackers to cause a reload of the affected devices, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCuh19936. The vulnerability is caused by the program not filtering PPTP packets correctly
