Vulnerability from variot - Updated: 2025-04-20 23:40

A Denial of Service Vulnerability in 802.11 ingress connection authentication handling for the Cisco Mobility Express 2800 and 3800 Access Points (APs) could allow an unauthenticated, adjacent attacker to cause authentication to fail. Affected Products: This vulnerability affects Cisco Mobility Express 2800 Series and 3800 Series Access Points when configured in local mode in 40 MHz. More Information: CSCvb33575. Known Affected Releases: 8.2(121.12) 8.4(1.82). Known Fixed Releases: 8.2(131.2) 8.2(131.3) 8.2(131.4) 8.2(141.0) 8.3(104.53) 8.3(104.54) 8.4(1.80) 8.4(1.85). Vendors have confirmed this vulnerability Bug ID CSCvb33575 It is released as.Denial of service by an adjacent attacker ( Authentication failure ) There is a possibility of being put into a state. The Cisco Mobility Express 2800 and 3800 AccessPoints are wireless products based on the Mobility Express solution from Cisco. An attacker could exploit this vulnerability to cause a denial of service. This issue is being tracked by Cisco Bug ID CSCvb33575. The vulnerability stems from the fact that the program does not correctly handle 802.11 authentication request errors. An attacker could exploit this vulnerability by sending a specially crafted 802.11 frame to the target device to affect the availability of the device

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.
