VAR-201310-0504

Vulnerability from variot - Updated: 2025-04-11 23:10

Cisco Identity Services Engine does not properly restrict the creation of guest accounts, which allows remote attackers to cause a denial of service (exhaustion of the account supply) via a series of requests within one session, aka Bug ID CSCue94287. Cisco Identity Services Engine is prone to a remote denial-of-service vulnerability. Successfully exploiting this issue may allow an attacker to cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCue94287. The platform monitors the network by collecting real-time information on the network, users and devices, and formulating and implementing corresponding policies

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.
