CVE-2025-2611 is a critical vulnerability affecting ICT Innovations' ICTBroadcast application, specifically versions 7.4 and below. The root cause is improper input validation (CWE-20) where the application unsafely passes session cookie data directly into shell processing commands. This flaw allows an unauthenticated attacker to inject arbitrary shell commands via the session cookie, which are then executed on the server hosting ICTBroadcast. Because the vulnerability does not require any authentication or user interaction, it enables remote code execution (RCE) with the privileges of the application process. The CVSS 4.0 score of 9.3 reflects the high impact and ease of exploitation: the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and results in high confidentiality, integrity, and availability impacts (VC:H, VI:L, VA:L). The scope is high (S: H), indicating that the vulnerability can affect resources beyond the vulnerable component, and the security requirements for integrity, confidentiality, and availability are all high (SI:H, SC:H, SA:H). This vulnerability is particularly dangerous because ICTBroadcast is a telephony and communication automation platform often used in call centers and enterprises for broadcasting voice, SMS, and email campaigns. Exploiting this flaw could allow attackers to execute arbitrary commands, potentially leading to full system compromise, data theft, disruption of communication services, or pivoting to other internal systems. No patches are currently listed, and no known exploits are reported in the wild yet, but the critical severity and ease of exploitation make this a high-priority issue for affected organizations to address immediately.

For European organizations using ICTBroadcast, the impact of CVE-2025-2611 could be severe. The vulnerability enables unauthenticated remote code execution, which can lead to complete system compromise. This threatens the confidentiality of sensitive customer and business data processed through ICTBroadcast, including call records, contact lists, and campaign data. Integrity of communication workflows can be disrupted, potentially causing misinformation or loss of trust in communication channels. Availability is also at risk, as attackers could disrupt or disable telephony services critical for customer support, emergency notifications, or internal communications. Given the reliance on ICTBroadcast in sectors such as telecommunications, customer service, and marketing, exploitation could cause operational downtime and financial losses. Additionally, compromised systems could be leveraged as footholds for lateral movement within enterprise networks, increasing the risk of broader breaches. European organizations must consider compliance implications, as data breaches involving personal data could trigger GDPR penalties. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous in automated or exposed environments, increasing the likelihood of exploitation if unmitigated.

1. Immediate mitigation should include isolating ICTBroadcast servers from direct internet exposure by placing them behind firewalls or VPNs restricting access to trusted IPs only. 2. Monitor network traffic for unusual session cookie values or shell command patterns indicative of exploitation attempts. 3. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious input in session cookies, especially shell metacharacters or command injection patterns. 4. Conduct thorough input validation and sanitization on all session cookie data before any processing, ideally by updating or patching the ICTBroadcast application once a vendor fix is available. 5. If patching is not immediately possible, consider disabling or restricting features that process session cookies in shell commands or running ICTBroadcast with least privilege to limit the impact of potential exploitation. 6. Regularly audit and review server logs for signs of unauthorized command execution or anomalous activity. 7. Develop an incident response plan specific to this vulnerability to quickly isolate and remediate affected systems if exploitation is detected. 8. Engage with ICT Innovations for updates or patches and subscribe to vulnerability advisories to stay informed about fixes and exploit developments.
