Title
Cisco Integrated Management Controller Software Authorization Bypass Vulnerability
Summary
A vulnerability in the API endpoints of Cisco Integrated Management Controller could allow an authenticated, remote attacker to bypass authorization and take actions on a vulnerable system without authorization.
The vulnerability is due to improper authorization checks on API endpoints. An attacker could exploit this vulnerability by sending malicious requests to an API endpoint. An exploit could allow the attacker to download files from or modify limited configuration options on the affected system.There are no workarounds that address this vulnerability.

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.
