The vulnerability is due to how the 802.1x packets are handled in the process path. An attacker could exploit this vulnerability by attempting to connect to the network on an 802.1x configured port. A successful exploit could allow the attacker to intermittently obtain access to the network. Cisco IOS There is an authentication vulnerability in the software.Information may be tampered with. This may lead to further   attacks. \nThis issue is tracked by Cisco Bug ID CSCvk25074. Cisco Catalyst 6500 Series Switches is a 6500 series modular chassis switch of Cisco (Cisco).

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.
