The mod_php module for the Apache HTTP Server allows local users with write access to PHP scripts to send signals to the server's process group and use the server's file descriptors, as demonstrated by sending a STOP signal, then intercepting incoming connections on the server's TCP port. NOTE: the PHP developer has disputed this vulnerability, saying "The opened file descriptors are opened by Apache. It is the job of Apache to protect them ... Not a bug in PHP.

Security readout for executives and security teams

CVE-2003-1307 concerns Apache running PHP through mod_php on systems where local or hosted users can write PHP scripts. The reported issue is that such a user could interfere with the Apache process group and inherited file descriptors. The vulnerability is disputed by PHP developers, and the supplied data does not identify fixed versions or active exploitation. Most relevant exposure is legacy Apache deployments using mod_php where semi-trusted users can upload, edit, or execute PHP scripts, especially shared hosting. Exposure is unclear for modern packaged Apache/PHP stacks because the source bundle provides no affected versions or vendor fix mapping. Treat this as a legacy shared-hosting risk, not a broad internet-facing emergency based on the supplied evidence. Prioritize review if the organization still hosts untrusted PHP authors on Apache/mod_php. Otherwise, track through normal legacy-platform risk management. Mitigation focus: Identify Apache deployments running PHP through mod_php.; Remove untrusted users' ability to write executable PHP scripts.; Separate tenants with OS, container, or process-level isolation..
