CVE-2009-0037 affects curl and libcurl versions 5.11 through 7.19.3 when CURLOPT_FOLLOWLOCATION is enabled. The redirect implementation accepts arbitrary Location header values without restricting the destination scheme or target. A malicious HTTP server can redirect a client to internal network resources, a file URL, or an SCP URL, causing the client to issue requests to unintended destinations, access local files, or invoke SCP-based command execution behavior.
