phpDocumentor File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA18248

VERIFY ADVISORY:
http://secunia.com/advisories/18248/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
phpDocumentor 1.x
http://secunia.com/product/6710/

DESCRIPTION:
rgod has discovered two vulnerabilities in phpDocumentor, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed to the "FORUM[LIB]" parameter in
"Documentation/tests/bug-559668.php" and the "root_dir" parameter in
"docbuilder/file_dialog.php" isn't properly verified, before it is
used to include files. This can be exploited to include arbitrary
files from external and local resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities have been confirmed in versions 1.2.3 and
1.3.0rc4 (except for the "root_dir" parameter which only has been
confirmed in version 1.3.0rc4). Prior versions are reportedly also
affected. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.

Set "register_globals" to "Off".

PROVIDED AND/OR DISCOVERED BY:
