Description

According to its banner, the version of PHP installed on the remote host is earlier than 5.3.11, and as such is potentially affected by multiple vulnerabilities :

  • During the import of environment variables, temporary changes to the 'magic_quotes_gpc' directive are not handled properly. This can lower the difficulty for SQL injection attacks. (CVE-2012-0831)

  • The '$_FILES' variable can be corrupted because the names of uploaded files are not properly validated. (CVE-2012-1172)

  • The 'open_basedir' directive is not properly handled by the functions 'readline_write_history' and 'readline_read_history'.

  • The 'header()' function does not detect multi-line headers with a CR. (Bug #60227 / CVE-2011-1398)
