Severity by source
AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N
PR:H because valid admin credentials are mandatory; I:H for arbitrary data modification, and C:L (vs vendor C:N) since the description explicitly states unauthorized data can be viewed.

2DescriptionNVD
A vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct an SQL or HQL injection attack on an affected device.
This vulnerability is due to insufficient validation of user-supplied input to the affected APIs before it is used to build database queries. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to execute arbitrary SQL or HQL queries against the underlying database, which could allow the attacker to view or modify data that they are not authorized to access. To exploit this vulnerability, the attacker must have valid administrative credentials.
AnalysisAI
Authenticated administrative users of Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) can exploit insufficient input validation in affected APIs to perform SQL/HQL injection, enabling them to view or modify unauthorized database data, with a high integrity impact and low confidentiality impact. The vulnerability affects ISE/ISE-PIC versions 3.1 through 3.5 and requires valid administrative credentials; no public exploit identified at time of analysis.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid administrative credentials on the Cisco ISE or ISE-PIC device (PR:H) - this is the primary limiting factor and rules out unauthenticated attackers. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but privilege-gated integrity risk rather than an urgent internet-facing crisis. … 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 | Refer to the Cisco security advisory (cisco-sa-ise-multisql-inject-JnHK54Rq) for patched versions and apply them if available; no specific fix version is provided in the input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
