The buffer_urldecode function in Lighttpd 1.3.7 and earlier does not properly handle control characters, which allows remote attackers to obtain the source code for CGI and FastCGI scripts via a URL with a %00 (null) character after the file extension.

Security readout for executives and security teams

This old Lighttpd flaw can let a remote user retrieve CGI or FastCGI script source code instead of having the script execute. That can expose application logic, credentials, database details, or other secrets embedded in scripts. The bundle does not provide a CVSS score or current exploitation evidence. Exposure is most likely on legacy Lighttpd deployments running version 1.3.7 or earlier with CGI or FastCGI enabled and publicly reachable script paths. Modern or unsupported assets may still exist in forgotten embedded, lab, or long-lived server environments. Handle as a legacy exposure cleanup item with moderate urgency. It is not KEV-listed in the bundle, but source disclosure can expose secrets and accelerate compromise if old public Lighttpd CGI/FastCGI services remain online. Mitigation focus: Inventory Lighttpd servers and identify versions 1.3.7 or earlier.; Prioritize internet-facing systems using CGI or FastCGI scripts.; Review the Lighttpd and Gentoo advisories for supported remediation guidance..
