PHP is a general-purpose scripting language widely used to develop web-based applications. It can run inside a web server using the mod_php module or the CGI version and also stand-alone in a CLI.


Multiple vulnerabilities have been found and fixed in PHP:

  • a possible $GLOBALS variable overwrite problem through file upload handling, extract() and import_request_variables() (CVE-2005-3390)
  • a local Denial of Service through the use of the session.save_path option (CVE-2005-3319)
  • an issue with trailing slashes in allowed basedirs (CVE-2005-3054)
  • an issue with calling virtual() on Apache 2, allowing to bypass safe_mode and open_basedir restrictions (CVE-2005-3392)
  • a problem when a request was terminated due to memory_limit constraints during certain parse_str() calls (CVE-2005-3389)
  • The curl and gd modules allowed to bypass the safe mode open_basedir restrictions (CVE-2005-3391)
  • a cross-site scripting (XSS) vulnerability in phpinfo() (CVE-2005-3388)


Attackers could leverage these issues to exploit applications that are assumed to be secure through the use of proper register_globals, safe_mode or open_basedir parameters. Remote attackers could also conduct cross-site scripting attacks if a page calling phpinfo() was available. Finally, a local attacker could cause a local Denial of Service using malicious session.save_path options.


There is no known workaround that would solve all issues at this time.
