In plain language
What this advisory means
A security weakness was found in the web management interface of Cisco Unified Intelligence Center. An attacker who already has authorized access could exploit this flaw to run hidden database commands and see sensitive data stored inside the device. Cisco has released updates to fix this issue, and there are no other workarounds to prevent this risk.
Technical explanation
How the issue affects the environment
The vulnerability resides in insufficient validation of user inputs in the web-based management interface of Cisco Unified Intelligence Center. This flaw allows an authenticated local attacker to conduct a blind SQL injection attack by sending specially crafted requests. Successful exploitation could disclose contents of the internal device database. Exploitation requires valid user credentials. Cisco assigned this vulnerability CVE-2026-20327 with a CVSS base score of 6.5 (medium severity). Cisco has provided fixed software releases starting with versions 12.6(2) ES08 and 15.0(1) SU2. There are no viable workarounds; upgrading to patched software is necessary to remediate the issue.
Operational impact
Why teams should care
An attacker with legitimate access to the Cisco Unified Intelligence Center system could gain unauthorized visibility into sensitive internal data through this SQL injection vulnerability. Exposure of confidential or operational information can lead to data breaches and potential compromise of system integrity. Organizations should prioritize updating affected systems to maintain confidentiality and protect business data.
Immediate action
Cisco strongly recommends upgrading Cisco Unified Intelligence Center to software versions 12.6(2) ES08, 15.0(1) SU2, or later to fully remediate the SQL injection vulnerability. Customers should access Cisco’s software download portals or contact Cisco Technical Assistance Center for upgrade assistance.
