Interpretation conflict in ModSecurity (mod_security) 2.1.0 and earlier allows remote attackers to bypass request rules via application/x-www-form-urlencoded POST data that contains an ASCIIZ (0x00) byte, which mod_security treats as a terminator even though it is still processed as normal data by some HTTP parsers including PHP 5.2.0, and possibly parsers in Perl, and Python.

According to its banner, the version of ModSecurity installed on the remote host is earlier than 2.1.1.  It is, therefore, potentially affected by a security bypass vulnerability.  An error exists related to HTTP POST requests and 'application/x-www-form-urlencoded' content containing un-encoded NULL bytes that could allow a remote attacker to bypass certain filters and carry out attacks.

Note that Nessus has not tested for this issue but has instead relied only on the version in the server's banner.

The remote host is running Oracle Application Server. It was not possible to determine its version, so the version of Oracle Application Server installed on the remote host could potentially be affected by multiple vulnerabilities :

The remote host is affected by the vulnerability described in GLSA-200705-17 (Apache mod_security: Rule bypass)

    Stefan Esser discovered that mod_security processes NULL characters as     terminators in POST requests using the     application/x-www-form-urlencoded encoding type, while other parsers     used in web applications do not.
  Impact :

    A remote attacker could send a specially crafted POST request, possibly     bypassing the module ruleset and leading to the execution of arbitrary     code in the scope of the web server with the rights of the user running     the web server.
  Workaround :

    There is no known workaround at this time.
