CVE-2025-2611 is an OS command injection vulnerability classified under CWE-78, affecting ICT Innovations' ICTBroadcast software versions 7.4 and earlier. The root cause is the unsafe processing of session cookie data, which is passed directly to shell commands without proper sanitization or neutralization of special characters. This flaw enables unauthenticated attackers to craft malicious session cookies that, when processed by the server, execute arbitrary shell commands with the privileges of the ICTBroadcast service. The vulnerability requires no authentication or user interaction, significantly lowering the barrier for exploitation. Successful exploitation can lead to full remote code execution, allowing attackers to compromise system confidentiality by accessing sensitive data, integrity by modifying or deleting data, and availability by disrupting services or deploying ransomware. The CVSS 4.0 base score of 9.3 reflects the vulnerability's critical nature, with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability also has high impact on confidentiality, integrity, and availability, with scope and security requirements changes. Although no public exploits are currently known, the severity and ease of exploitation make it a high-priority issue. ICTBroadcast is widely used in telephony and broadcasting services, making this vulnerability particularly dangerous for organizations relying on these services. Defenders should prioritize patching once available, implement strict input validation to sanitize session cookies, isolate session handling processes to limit command injection impact, and deploy monitoring to detect anomalous command execution patterns.

For European organizations, especially those in telecommunications and broadcasting sectors using ICTBroadcast, this vulnerability poses a severe risk. Exploitation can lead to complete system compromise, resulting in data breaches, service outages, and potential disruption of critical communication infrastructure. Confidentiality breaches could expose sensitive customer or operational data, while integrity violations might allow attackers to alter call routing or broadcast content. Availability impacts could disrupt telephony services, affecting business continuity and emergency communications. Given the strategic importance of telecom infrastructure in Europe, successful attacks could have cascading effects on other sectors relying on these services. The lack of authentication and user interaction requirements increases the likelihood of automated attacks, potentially leading to widespread exploitation if unpatched. Organizations in countries with significant ICTBroadcast deployments and advanced telecom sectors, such as Germany, France, and the UK, face heightened exposure and potential regulatory scrutiny under GDPR if personal data is compromised.

1. Immediate application of vendor patches once released is critical to remediate the vulnerability. 2. Until patches are available, implement strict input validation and sanitization on all session cookie data to prevent injection of shell metacharacters. 3. Isolate session handling processes in sandboxed or containerized environments to limit the scope of command execution. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious session cookie patterns indicative of injection attempts. 5. Monitor system logs and command execution traces for anomalies or unexpected shell commands originating from session handling components. 6. Restrict ICTBroadcast service privileges to the minimum necessary to reduce impact of potential exploitation. 7. Conduct regular security audits and penetration testing focusing on session management and command execution paths. 8. Educate IT and security teams about the vulnerability specifics to improve detection and response readiness. 9. Consider network segmentation to isolate ICTBroadcast servers from critical infrastructure where feasible. 10. Maintain up-to-date backups to enable recovery in case of compromise.
