AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N
Authenticated low-priv admin (PR:L) over the network (AV:N/AC:L) performing SQLi; read gives limited C:L, data modification gives I:H, no availability impact and same-security-scope database (S:U).

Lifecycle Timeline
2DescriptionNVD
A vulnerability in Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected device. To exploit this vulnerability, the attacker must have at least low-privileged administrative credentials.
This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to read or modify data in the underlying database.
AnalysisAI
SQL injection in Cisco Identity Services Engine (ISE) 3.1.0 through 3.5 lets an authenticated attacker with low-privileged administrative credentials read or modify data in the underlying database by sending a single crafted request to the management interface; no user interaction is required and the vector is network-reachable (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N, 7.1). Because exploitation is gated behind valid administrative credentials, the practical exposure depends heavily on how tightly ISE management and API interfaces are restricted to trusted admin networks. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires valid low-privileged administrative credentials to the Cisco ISE management interface (PR:L) - this is an authenticated attack, not exploitable by anonymous remote actors. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but access-gated issue rather than a drop-everything emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Cisco is the reporting source and the advisory at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-sql-inj-3QTKR947 is the authoritative source for fixed software - no explicit fixed version is provided in the available intelligence, so confirm the validated fixed release for your train against that advisory before upgrading and verify the patch level actually appears on the affected list (ISE 3.1.0 through 3.5.0 including numerous patch levels) rather than assuming a current patch means you are covered. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict access to Cisco ISE management and API interfaces to trusted administrative networks only, enforce least privilege for all administrative accounts, and enable detailed logging and monitoring for SQL injection attempts or anomalous database queries. …
