To exploit this vulnerability, the attacker must have valid administrative credentials.\r\n\r\nThis vulnerability is due to insufficient validation of user-supplied input by the affected feature. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface of an affected device. A successful exploit could allow the attacker to read arbitrary files from the affected device, which could contain sensitive information.\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-multi-traversal-WDTgYCdn** · 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-multi-traversal-WDTgYCdn)","depth":"sunlit","depthScore":27,"depthScoreParts":{"impact":27,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
