Buffer overflow in the fcgi_env_add function in mod_proxy_backend_fastcgi.c in the mod_fastcgi extension in lighttpd before 1.4.18 allows remote attackers to overwrite arbitrary CGI variables and execute arbitrary code via an HTTP request with a long content length, as demonstrated by overwriting the SCRIPT_FILENAME variable, aka a "header overflow."

Security readout for executives and security teams

CVE-2007-4727 is a vulnerability in lighttpd’s mod_fastcgi extension before version 1.4.18. A remote attacker could send a specially large HTTP content length and corrupt FastCGI environment data, potentially leading to arbitrary code execution. This matters mainly for legacy lighttpd deployments still running the vulnerable module. Exposure is likely limited to legacy systems running lighttpd before 1.4.18 with mod_fastcgi enabled. Internet-facing web servers or embedded appliances using that stack deserve priority review. The bundle does not identify affected downstream products beyond distribution advisories. Treat this as a legacy remote-code-execution risk. It is urgent only where old lighttpd FastCGI servers remain exposed, but those systems should be found and removed or upgraded quickly. Mitigation focus: Identify any lighttpd deployments older than 1.4.18.; Upgrade lighttpd to 1.4.18 or later where applicable.; Check vendor or distribution advisories for backported fixes..
