CVE-2018-15962: Directory listing in Adobe ColdFusion
Adobe ColdFusion versions July 12 release (2018.0.0.310739), Update 6 and earlier, and Update 14 and earlier have a directory listing vulnerability. Successful exploitation could lead to information disclosure.
AI Analysis
Technical Summary
CVE-2018-15962 is a directory listing vulnerability affecting Adobe ColdFusion versions including the July 12 release (2018.0.0.310739), Update 6 and earlier, and Update 14 and earlier. This vulnerability allows an unauthenticated remote attacker to access directory listings on the affected ColdFusion servers. Directory listing vulnerabilities occur when a web server is configured to display the contents of directories without an index file, enabling attackers to view files and folders that may contain sensitive information. In this case, the vulnerability is classified under CWE-200 (Information Exposure), indicating that it can lead to unauthorized disclosure of information. The CVSS v3.1 base score is 5.3 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impact limited to confidentiality (C:L) without affecting integrity or availability. Exploitation does not require authentication or user interaction, making it relatively straightforward for attackers to probe vulnerable ColdFusion servers remotely. Although no known exploits are reported in the wild, the vulnerability could be leveraged by attackers to gather information about the server environment, directory structure, configuration files, or other sensitive data that could facilitate further attacks or reconnaissance. Adobe ColdFusion is a commercial rapid web application development platform widely used for building enterprise web applications and APIs. The affected versions are relatively old, but organizations that have not applied updates or patches remain at risk. The lack of a patch link in the provided data suggests that users should consult Adobe’s official security advisories for remediation steps. Overall, this vulnerability represents a moderate risk primarily due to information disclosure, which could be a stepping stone for more severe attacks if combined with other vulnerabilities or misconfigurations.
Potential Impact
For European organizations using affected versions of Adobe ColdFusion, this vulnerability poses a risk of unauthorized information disclosure. Attackers could obtain directory listings revealing sensitive files such as configuration files, source code, or credentials stored in accessible directories. This exposure can facilitate targeted attacks, including privilege escalation, data theft, or deployment of malware. The impact is particularly significant for organizations handling sensitive personal data or critical business applications, as information leakage could violate GDPR requirements and lead to regulatory penalties. Additionally, public sector entities, financial institutions, and healthcare providers in Europe often rely on ColdFusion for legacy applications, increasing their exposure. While the vulnerability does not directly compromise system integrity or availability, the confidentiality breach could undermine trust and lead to reputational damage. The ease of exploitation without authentication means attackers can scan and identify vulnerable servers en masse, increasing the likelihood of opportunistic attacks. Therefore, European organizations must consider this vulnerability seriously, especially those with internet-facing ColdFusion servers or insufficient network segmentation.
Mitigation Recommendations
1. Immediate upgrade: Organizations should upgrade Adobe ColdFusion to the latest available version beyond Update 14 or the July 12 release to ensure the vulnerability is patched. 2. Disable directory listing: As a best practice, explicitly disable directory listing in the web server configuration (e.g., Apache, IIS) hosting ColdFusion applications to prevent exposure regardless of application-level vulnerabilities. 3. Restrict access: Implement network-level controls such as firewalls or web application firewalls (WAFs) to restrict access to ColdFusion administrative and application directories, limiting exposure to trusted IP addresses only. 4. Conduct security audits: Perform regular security assessments and directory traversal scans to detect unintended directory listings or sensitive file exposures. 5. Monitor logs: Enable detailed logging and monitor for unusual access patterns or directory enumeration attempts targeting ColdFusion servers. 6. Harden ColdFusion configuration: Review and harden ColdFusion server settings to minimize information disclosure, including disabling debug output and verbose error messages. 7. Segmentation and isolation: Isolate ColdFusion servers from critical internal networks to reduce the blast radius in case of compromise. 8. Incident response readiness: Prepare incident response plans to quickly address any detected exploitation attempts or information leakage incidents related to this vulnerability.
