CVE-2025-20274 is a vulnerability identified in the web-based management interface of Cisco Unified Intelligence Center, a component of Cisco Unified Contact Center Express (UCCX). The flaw arises from improper validation of files uploaded through the interface, allowing an authenticated attacker with at least Report Designer role privileges to upload arbitrary files. This unrestricted file upload can lead to the storage of malicious files on the system and potentially enable execution of arbitrary commands on the underlying operating system. The vulnerability is significant because it allows privilege escalation to root, thereby granting full control over the affected device. The vulnerability affects a wide range of Cisco UCCX versions, spanning from 10.5(1) through various 12.5.x releases and their respective service updates and extensions. The CVSS v3.1 base score is 6.3 (medium severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impacts on confidentiality, integrity, and availability. No known exploits are reported in the wild yet, but the potential for severe impact exists given the ability to execute arbitrary commands and escalate privileges. Cisco Unified Contact Center Express is widely used in enterprise environments for customer interaction management, making this vulnerability a critical concern for organizations relying on these systems for their contact center operations.

For European organizations, the impact of this vulnerability can be substantial. Cisco UCCX is commonly deployed in large enterprises, telecommunications providers, and customer service centers across Europe. Exploitation could lead to unauthorized access to sensitive customer data, disruption of contact center operations, and potential lateral movement within corporate networks. Given the ability to escalate privileges to root, attackers could manipulate call routing, intercept or alter communications, and disrupt business continuity. This could result in reputational damage, regulatory non-compliance (especially under GDPR due to potential data breaches), and financial losses. The requirement for valid credentials with Report Designer role privileges somewhat limits the attack surface but does not eliminate risk, as insider threats or credential compromise through phishing or other means could enable exploitation. The broad range of affected versions means many organizations may be vulnerable if they have not applied patches or mitigations. The lack of known exploits in the wild currently provides a window for proactive defense, but the high impact potential necessitates urgent attention.

1. Immediate patching: Organizations should prioritize applying Cisco's security updates for all affected UCCX versions as soon as they become available. 2. Access control hardening: Restrict the number of users with Report Designer or equivalent privileges to the minimum necessary and enforce strong authentication mechanisms, including multi-factor authentication (MFA). 3. Monitoring and logging: Enable detailed logging of file upload activities and monitor for anomalous behavior indicative of exploitation attempts, such as unexpected file types or command execution attempts. 4. Network segmentation: Isolate the management interface of Cisco UCCX systems from general user networks and restrict access to trusted administrative hosts only. 5. Credential hygiene: Regularly audit and rotate credentials, and implement robust phishing awareness programs to reduce the risk of credential compromise. 6. File upload restrictions: Where possible, implement additional validation or filtering on uploaded files at network or application layers to detect and block suspicious content. 7. Incident response readiness: Prepare and test incident response plans specifically for potential exploitation scenarios involving contact center infrastructure.
