Detailsinfo

A vulnerability was found in Cisco Identity Services Engine. It has been rated as problematic. This issue affects an unknown part of the component APIs. The manipulation with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the APIs of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks against the backend database. This vulnerability is due to insufficient validation of certain parameters that are concatenated directly into an SQL query. An attacker could exploit this vulnerability by sending a crafted request that contains SQL statements to an affected endpoint. A successful exploit could allow the attacker to read arbitrary content from the SQL database and conduct server-side request forgery (SSRF) attacks. To exploit this vulnerability, the attacker must have valid administrative credentials.

The advisory is shared at sec.cloudapps.cisco.com. The identification of this vulnerability is CVE-2026-76425 since 08/19/2026. The exploitation is known to be easy. The attack may be initiated remotely. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/16/2026). MITRE ATT&CK project uses the attack technique T1505 for this issue.
