Vulnerability from variot - Updated: 2025-04-11 23:14

The OSPF functionality in Cisco IOS and IOS XE allows remote attackers to cause a denial of service (device reload) via crafted options in an LSA type 11 packet, aka Bug ID CSCui21030. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. Exploiting this issue may allow attackers to cause a reload of the affected device. This may cause denial-of-service conditions. This issue is being tracked by Cisco Bug ID CSCui21030

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.
