CVE-2025-20377 — Cisco Unified Intelligence Center API Information Disclosure Vulnerability

A vulnerability in the API subsystem of Cisco Unified Intelligence Center could allow an authenticated, remote attacker to obtain sensitive information from an affected system. This vulnerability is due to improper validation of requests to certain API endpoints. An attacker could exploit this vulnerability by sending a valid request to a specific API endpoint within the affected system. A successful exploit could allow a low-privileged user to view sensitive information on the affected system that should be restricted. To exploit this vulnerability, the attacker must have valid user credentials on the affected system.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.3% (30-day exploitation probability)+3
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Cisco Packaged Contact Center Enterprise, Cisco Unified Contact Center Enterprise, Cisco Unified Contact Center Express…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
