Adobe ColdFusion 2023.6 - Remote File Read
Adobe ColdFusion 2023.6 - Remote File Read
AI Analysis
Technical Summary
The security threat pertains to a remote file read vulnerability in Adobe ColdFusion 2023.6. Adobe ColdFusion is a commercial rapid web application development platform used to build and deploy web applications. A remote file read vulnerability allows an attacker to read arbitrary files from the server hosting the ColdFusion instance without authentication or with minimal privileges. This can lead to exposure of sensitive configuration files, source code, credentials, or other critical data stored on the server. The exploit is classified as 'remote' and 'web' indicating it can be triggered over the network via web requests. The presence of exploit code written in Python suggests that the vulnerability can be actively exploited by attackers with moderate technical skills. Although no specific affected versions are listed, the reference to ColdFusion 2023.6 implies the vulnerability affects this particular version or patch level. The lack of patch links indicates that either a fix is not yet publicly available or not documented in the source. The absence of known exploits in the wild suggests this is a newly disclosed or proof-of-concept exploit rather than a widespread active threat at this time. However, the medium severity rating indicates a significant risk if exploited, especially given the sensitive nature of data that could be exposed through remote file read. The vulnerability does not require user interaction and can be exploited remotely, increasing its risk profile. Overall, this vulnerability represents a critical information disclosure risk that could facilitate further attacks such as privilege escalation or lateral movement within a compromised environment.
Potential Impact
For European organizations, the impact of this vulnerability can be substantial. Many enterprises and public sector entities in Europe use Adobe ColdFusion for internal and external web applications, including critical business processes and customer-facing portals. Exploitation could lead to unauthorized access to sensitive personal data protected under GDPR, intellectual property, and internal credentials. This exposure could result in regulatory fines, reputational damage, and operational disruption. Additionally, attackers could leverage the information gained from file reads to conduct further attacks such as injecting malicious code, escalating privileges, or moving laterally within the network. The medium severity rating suggests that while the vulnerability may not directly cause system takeover, the confidentiality breach alone is a serious concern. European organizations in sectors such as finance, healthcare, government, and manufacturing, which often rely on ColdFusion-based applications, are particularly at risk. The remote nature of the exploit means attackers do not need internal network access, increasing the threat from external adversaries including cybercriminals and state-sponsored actors.
Mitigation Recommendations
Given the absence of official patches or updates, European organizations should immediately implement compensating controls. These include restricting network access to ColdFusion servers by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. Organizations should audit and monitor web server logs for unusual file access patterns indicative of exploitation attempts. Applying web application firewalls (WAFs) with custom rules to detect and block suspicious file read requests can provide an additional layer of defense. Administrators should review ColdFusion server configurations to disable or restrict file system access where possible and ensure that sensitive files are stored outside of web root directories. Regular backups and incident response plans should be updated to prepare for potential data breaches. Once Adobe releases an official patch, organizations must prioritize timely deployment. Additionally, conducting penetration testing and vulnerability assessments focused on ColdFusion instances can help identify and remediate this and related vulnerabilities proactively.
