An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to execute arbitrary SQL or HQL queries against the underlying database, which could allow the attacker to view or modify data that they are not authorized to access. To exploit this vulnerability, the attacker must have valid administrative credentials.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **cisco-sa-ise-multisql-inject-JnHK54Rq** · Cisco · affected: Cisco ISE Passive Identity Connector (4 versions), Cisco Identity Services Engine Software (46 versions) · updated 2026-09-16 · [advisory](https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-multisql-inject-JnHK54Rq)","depth":"sunlit","depthScore":27,"depthScoreParts":{"impact":27,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
