VAR-201504-0269
Vulnerability from variot - Updated: 2023-12-18 12:20Cisco IOS XE 3.10.2S on an ASR 1000 device with an Embedded Services Processor (ESP) module, when NAT is enabled, allows remote attackers to cause a denial of service (module crash) via malformed H.323 packets, aka Bug ID CSCup21070. Cisco ASR is an integrated services router solution from Cisco that uses the IOS XR Software module operating system to provide carrier-class reliability. A denial of service vulnerability exists in the Cisco ASR 1000 appliance, allowing remote attackers to exploit the vulnerability to initiate a denial of service attack through the H323 protocol packet. Attackers can exploit this issue to crash the affected device, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCup21070
