CVE-2026-20285: Improper Authorization in Cisco Cisco Identity Services Engine Software
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to modify parts of the configuration on an affected device. This vulnerability is due to the lack of server-side validation of Administrator permissions. An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to modify descriptions of files on a specific page. To exploit this vulnerability, an attacker would need valid Administrator credentials.
AI Analysis
Technical Summary
This vulnerability arises from a lack of server-side validation of Administrator permissions in the web-based management interface of Cisco ISE and ISE-PIC. An authenticated remote attacker with valid Administrator credentials can exploit this by sending crafted HTTP requests to modify parts of the device configuration, specifically file descriptions on a certain page. The CVSS 3.1 base score is 4.3, reflecting low complexity and privileges required but limited impact (integrity only). There is no indication of known exploits in the wild or cloud service involvement.
Potential Impact
The vulnerability allows an attacker with valid Administrator credentials to modify configuration descriptions, impacting the integrity of the system configuration. There is no impact on confidentiality or availability. This could lead to misleading configuration information but does not directly enable data disclosure or service disruption.
Mitigation Recommendations
No vendor advisory or patch information is provided in the input data. Patch status is not yet confirmed — check Cisco's official advisory for current remediation guidance. Until a patch is available, ensure that Administrator credentials are tightly controlled and monitor for unauthorized configuration changes.
