Vulnerability from github – Published: 2026-09-16 21:32 – Updated: 2026-09-16 21:32

Details

A vulnerability in the REST API of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to conduct SQL injection attacks against the monitoring database.

This vulnerability is due to insufficient validation of specific parameters that are then concatenated into an SQL statement. An attacker could exploit this vulnerability by sending a crafted request that contains SQL statements in one of the affected parameters. A successful exploit could allow the attacker to read information from the monitoring database. To exploit this vulnerability, the attacker must have valid administrative credentials.

Severity

4.9 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N

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.
