VAR-201508-0098
Vulnerability from variot - Updated: 2025-04-13 23:18Cisco IOS XE 2.1.0 through 2.4.3 and 2.5.0 on ASR 1000 devices, when NAT Application Layer Gateway is used, allows remote attackers to cause a denial of service (Embedded Services Processor crash) via a crafted SIP packet, aka Bug IDs CSCta74749 and CSCta77008. Vendors have confirmed this vulnerability Bug ID CSCta74749 ,and CSCta77008 It is released as.Skillfully crafted by a third party SIP Service disruption via packets ( Embedded service processor crash ) There is a possibility of being put into a state. The Cisco ASR1000 Series Aggregation Services Router provides a WAN edge solution that combines information, communications, collaboration and business. The Cisco ASR 1000 Series Router handles SIP packets with security vulnerabilities, allowing remote attackers to exploit vulnerabilities by sending special packets to crash the target ESP and overload the target device. Cisco IOS XE on ASR 1000 is an operating system developed by Cisco in the ASR 1000 series routers. A security vulnerability exists in Cisco IOS XE Releases 2.1.0 through 2.4.3 and 2.5.0 on Cisco ASR 1000 devices
