VAR-201405-0366

Vulnerability from variot - Updated: 2025-04-12 23:32

The DHCPv6 implementation in Cisco IOS XR allows remote attackers to cause a denial of service (device crash) via a malformed packet, aka Bug IDs CSCum85558, CSCum20949, CSCul61849, and CSCul71149. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. Attackers can exploit this issue to cause the affected device to crash, denying service to legitimate users. This issue is being tracked by Cisco Bug IDs CSCum85558, CSCum20949, CSCul61849, and CSCul71149

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
