ColdFusion XSS (CVE-2023-44352)
Description
Adobe ColdFusion versions prior to the security updates released in APSB23-52 contain a cross-site scripting (XSS) vulnerability due to improper sanitization of user-supplied input in URL path parameters. This reflected XSS vulnerability allows attackers to inject malicious scripts that execute in the context of a victim's browser session when they access a specially crafted URL.
Remediation
Apply the security updates provided in Adobe Security Bulletin APSB23-52 immediately. Specifically:
1. Identify your current ColdFusion version (ColdFusion 2023, 2021, or 2018)
2. Download and install the appropriate security update from the Adobe ColdFusion security bulletin (APSB23-52)
3. Restart the ColdFusion service after applying the update
4. Verify the patch installation by checking the ColdFusion Administrator version information
5. As an additional defense-in-depth measure, implement Content Security Policy (CSP) headers to mitigate XSS risks
6. Review application logs for any suspicious activity that may indicate prior exploitation attempts
If immediate patching is not possible, implement a web application firewall (WAF) rule to filter malicious input in URL paths as a temporary mitigation measure.
