PHP 4.x to 4.3.9, and PHP 5.x to 5.0.2, when running in safe mode on a multithreaded Unix webserver, allows local users to bypass safe_mode_exec_dir restrictions and execute commands outside of the intended safe_mode_exec_dir via shell metacharacters in the current directory name. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

REVIEWING(1) Christey
Comments (Legacy)
 Christey> There is active disagreement regarding whether this satisfies the
   criteria for inclusion in CVE, because the attack vectors require
   function parameters that are typically controlled only by the
   application developer, not an external attacker.  This would mean that
   only the PHP application owner could exploit it.
   Since various PHP functions already allow the application owner to
   execute commands, no additional privileges would be gained by
   exploiting such a bug.  However, if safe_mode is enabled in PHP, then
   the PHP functions related to execution are restricted
   (e.g. shell_exec()).  Thus, exploitation may allow the PHP application
   owner to execute code *despite* the configured restrictions imposed by
   safe mode, which then qualifies this as a vulnerability.
