Steps

Written by AI from the record

Confirm whether your organization runs Cisco Identity Services Engine Software and identify all administrator accounts and API access points.
Restrict administrator and API access to trusted management networks, remove unused administrator accounts, and require strong multi-factor authentication where available.
Ask Cisco or your support provider for the remediation timeline; no fixed version or patch information is currently available.
Review Cisco ISE and database-access logs for unusual administrator API requests or unexpected requests to internal services.

What it is

From the CVE record

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.

In plain language

Written by AI from the record

This flaw in Cisco Identity Services Engine Software lets someone who already controls an administrator account reach its database, so businesses running it should treat it as urgent.

Authenticated remote SQL injection in Cisco Identity Services Engine Software APIs allows an administrator-level attacker to read arbitrary database content and conduct server-side request forgery.

If you're affected

Database data exposure
Internal service access
Identity-service disruption
Administrator account abuse

What is it

This is a flaw in software used to manage access to company networks and systems. It is like giving someone with a master key a way to alter the questions they ask the records room, potentially letting them look through protected records or send requests into other internal areas.

Who is affected

This matters to you if you run Cisco Identity Services Engine Software. It requires an attacker to already have valid administrative credentials, so it is only a risk when an administrator account can be compromised, misused, or accessed by an attacker.

How urgent is it

A public exploit is available, giving an attacker with administrator access a ready-made way to target the affected system. Treat this as a red-priority issue: reduce administrator and API exposure now while awaiting Cisco remediation information.

What to do — in detail

Confirm deployment by inventorying Cisco Identity Services Engine Software instances, their enabled API endpoints, and all administrator accounts. The findings do not provide affected-version ranges, fixed versions, or a patch; obtain the current vendor advisory and remediation guidance from Cisco or your support provider before scheduling an upgrade.

Until a vendor fix is available, limit administrative and API access to dedicated management networks, allow only approved administrator source addresses, remove dormant accounts, and enforce multi-factor authentication for administrative access where supported. Rotate credentials for administrator accounts that are no longer fully trusted, and investigate unusual crafted API parameters, unexpected database-query behavior, and outbound requests from Cisco ISE to internal services. CISA has not listed this CVE in KEV, so there is no CISA remediation due date.

Technical context

CVSS v3.1: 7.6 High (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N). CWE-89 SQL injection in Cisco ISE APIs arises from insufficient validation of parameters concatenated into SQL queries. A remote attacker with valid administrative credentials can submit crafted requests to read arbitrary SQL database content and perform SSRF. A public exploit is available; CISA KEV does not list the CVE. EPSS is 0.3% (22nd percentile) with a flat trend. The findings provide no patch or fixed-version information.

This is a general assessment based on public vulnerability data. It does not account for your specific infrastructure — when in doubt, consult a security specialist.
