CVE-2026-76428: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Cisco Cisco Identity Services Engine Software
A vulnerability in the REST APIs of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to conduct SQL injection attacks against the session database. This vulnerability is due to certain parameters being concatenated directly into SQL clauses without parameterization. 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 session database. To exploit this vulnerability, the attacker must have valid administrative credentials.
AI Analysis
Technical Summary
This vulnerability exists because certain parameters in the REST APIs of Cisco ISE and Cisco ISE-PIC are concatenated directly into SQL queries without proper parameterization, enabling SQL injection. An attacker with valid administrative credentials can send crafted requests containing malicious SQL statements to read sensitive information from the session database. The affected versions are Cisco ISE 3.1.0, 3.2.0, 3.3.0, 3.4.0, and 3.5.0. The CVSS v3.1 base score is 4.9, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and high confidentiality impact.
Potential Impact
An attacker with valid administrative credentials can exploit this vulnerability to read sensitive information from the session database via SQL injection. There is no impact on integrity or availability reported. The confidentiality of session data is at risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrative access to trusted personnel only and monitor for suspicious API activity. Do not expose administrative interfaces to untrusted networks.
