Description
The ICTBroadcast application unsafely passes session cookie data to shell processing, allowing an attacker to inject shell commands into a session cookie that get executed on the server. This results in unauthenticated remote code execution in the session handling. Versions 7.4 and below are known to be vulnerable.

Comprehensive Technical Analysis of EUVD-2025-23629
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-23629 pertains to the ICTBroadcast application, specifically versions 7.4 and below. The issue arises from the unsafe handling of session cookie data, which is passed to shell processing without proper sanitization. This allows an attacker to inject shell commands into the session cookie, leading to unauthenticated remote code execution (RCE).
Severity Evaluation:
- Base Score: 9.3 (Critical)
- Base Score Version: 4.0
- Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:L/SC:H/SI:H/SA:H
The high base score indicates a critical vulnerability due to the following factors:
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): Low (L)
- Privileges Required (PR): None (N)
- User Interaction (UI): None (N)
- Confidentiality (VC): High (H)
- Integrity (VI): Low (L)
- Availability (VA): Low (L)
- Scope Change (SC): High (H)
- Impact on Confidentiality (SI): High (H)
- Impact on Integrity (SI): High (H)
- Impact on Availability (SA): High (H)
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network-Based Attacks: Given the attack vector is network-based, an attacker can exploit this vulnerability remotely without needing physical access to the system.
- Session Cookie Manipulation: The primary attack vector involves manipulating session cookies to inject malicious shell commands.
Exploitation Methods:
- Shell Command Injection: An attacker can craft a session cookie containing shell commands. When the ICTBroadcast application processes this cookie, the injected commands are executed on the server.
- Automated Exploitation: Tools like Metasploit can be used to automate the exploitation process, as indicated by the reference to a Metasploit framework pull request.
3. Affected Systems and Software Versions
Affected Systems:
- All systems running ICTBroadcast versions 7.4 and below are vulnerable.
Software Versions:
- ICTBroadcast versions 0 through 7.4 are affected.
4. Recommended Mitigation Strategies
Immediate Mitigation:
- Patching: Upgrade to a version of ICTBroadcast higher than 7.4 if a patched version is available.
- Temporary Workaround: Disable session cookie processing or implement strict input validation and sanitization for session cookies.
Long-Term Mitigation:
- Code Review: Conduct a thorough code review to ensure all input handling, especially session cookies, is secure.
- Security Training: Educate developers on secure coding practices to prevent similar vulnerabilities in the future.
- Regular Updates: Implement a regular update and patch management process to ensure all software is up-to-date.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to organizations using ICTBroadcast within the European Union. Given the critical nature of the vulnerability, it could lead to:
- Data Breaches: Unauthorized access to sensitive data.
- Service Disruptions: Potential denial-of-service attacks.
- Compliance Issues: Violations of GDPR and other regulatory requirements due to unauthorized data access.
6. Technical Details for Security Professionals
Vulnerability Details:
- CVE ID: CVE-2025-2611
- Assigner: VulnCheck
- ENISA ID Product: 5d474a69-9c65-31ff-8d95-7dba0bb6f3a2
- ENISA ID Vendor: dc116598-c7bb-3868-bde3-e86a64c96bb4
Exploitation Steps:
- Craft Malicious Session Cookie: Create a session cookie containing shell commands.
- Send Cookie to Server: Send the crafted cookie to the ICTBroadcast server.
- Command Execution: The server processes the cookie, executing the injected commands.
Detection and Monitoring:
- Log Analysis: Monitor server logs for unusual shell command executions.
- Intrusion Detection Systems (IDS): Implement IDS to detect and alert on suspicious session cookie activities.
- Network Monitoring: Use network monitoring tools to detect anomalous traffic patterns indicative of exploitation attempts.
Conclusion: The vulnerability in ICTBroadcast versions 7.4 and below is critical and requires immediate attention. Organizations should prioritize patching and implementing mitigation strategies to protect against potential exploitation. Regular security audits and adherence to best practices in secure coding will help prevent similar issues in the future.
