CVE-2013-2779 describes a denial-of-service vulnerability in Cisco IOS XE on 1000 series Aggregation Services Routers (ASR). Specifically, versions 3.4 before 3.4.5S and 3.5 through 3.7 before 3.7.1S are affected due to improper implementation of the Multicast Leaf Recycle Elimination (MLRE) feature. Remote attackers can exploit this by sending fragmented IPv6 MVPN packets, leading to a card reload on the affected device. This vulnerability has a CVSS score of 7.8 (High), indicating a critical impact. It can be exploited remotely with low attack complexity and no authentication required, resulting in a complete loss of availability (card reload). There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, suggesting low public awareness.
