Remote Code Execution Vulnerability in Cisco Unified CCX Software

CVE-2025-20354

What is CVE-2025-20354?

CVE-2025-20354 is a severe vulnerability found in Cisco Unified Contact Center Express (CCX) software, which is widely used to manage customer interactions across various communication channels. This vulnerability stems from inadequate authentication mechanisms in the Java Remote Method Invocation (RMI) process linked to specific features of the software. An unauthenticated remote attacker can exploit this flaw by uploading malicious files to the system. The exploit allows attackers to execute arbitrary commands with root-level access, potentially resulting in significant control over the affected systems. Given that Cisco Unified CCX is integral to many organizations' customer service operations, such a breach could lead to operational disruptions, unauthorized access to sensitive data, and severe reputational repercussions.

Potential impact of CVE-2025-20354

1. Unauthorized System Control: Attackers can gain root-level access, allowing them to execute any command on the operating system, potentially leading to complete system takeover and unauthorized access to sensitive information.

2. Data Breach Risks: With elevated privileges, attackers can exfiltrate sensitive customer data, which may include personal identification information (PII) and confidential company information, leading to significant regulatory and financial penalties.

3. Operational Disruption: Exploitation of this vulnerability may disrupt critical customer service operations, resulting in downtime that can affect service delivery, customer satisfaction, and overall business productivity.
