The CVE-2025-20305 vulnerability stems from an improper data protection mechanism within Cisco ISE’s web-based management interface. Specific files containing sensitive data, such as passwords, lack sufficient access controls. An authenticated attacker with read-only Administrator privileges can exploit this flaw by sending crafted HTTP requests to certain endpoints. These endpoints return information that should be restricted to higher-privileged users. The application fails to properly validate the user’s privilege level before disclosing the contents of these protected files. Consequently, the attacker can access and view cleartext credentials that are normally obscured from a read-only account, leading to a confidentiality breach.
Platform: Cisco ISE

What Undercode Say:
`curl -X GET -H “Cookie: sessionid=READONLY_SESSION” https://
`grep -r “password” /web/interface/templates/`
`cat /ise/configuration/sensitive_data.xml`
How Exploit:
Authenticated read-only user accesses specific API endpoints or web interface components that improperly return sensitive data like unmasked passwords.
Protection from this CVE:
Apply Cisco update. Enforce least privilege. Review audit logs.
Impact:
Read-only admin can view sensitive information, including passwords, potentially leading to further privilege escalation.
