VAR-201609-0317
Vulnerability from variot - Updated: 2025-04-13 23:22Cisco AsyncOS through 9.5.0-444 on Web Security Appliance (WSA) devices allows remote attackers to cause a denial of service (link saturation) by making many HTTP requests for overlapping byte ranges simultaneously, aka Bug ID CSCuz27219. Cisco Web Security Appliance is prone to a denial-of-service vulnerability. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCuz27219. A remote attacker could exploit this vulnerability by sending a large number of specially crafted HTTP requests to cause a denial of service

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.
