Description:
Janek Vind has reported multiple vulnerabilities in XMB, allowing malicious people to conduct Cross Site Scripting and SQL injection attacks.
The Cross Site Scripting vulnerabilities are caused due to lack of input validation. Some vulnerabilities may require that certain characters are URL encoded. This allows malicious people to inject arbitrary HTML and script code.
1) "forumdisplay.php" fails to verify input to the "foobar" parameter.
2) "member.php" fails to verify input to the "member" parameter.
3) "u2uadmin.php" fails to verify input to the "uid" parameter.
4) "editprofile.php" fails to verify input to the "user" parameter.
The BBcode allowing users to format their messages can be exploited to inject arbitrary script code by including parameters with script code.
5) "[align=xxx][/align]" can be manipulated to execute javascript by including a "onmouseover" parameter in the "align" tag.
6) "[img=1x1][/img]" can contain arbitrary script code instead of an image reference if it is suffixed with ";//gif"
The SQL injection vulnerabilities are caused to due to lack of input validation. A sample exploit has been published which exploits issue 10 to reveal the administrative username and password hash.
7) "viewthread.php" fails to verify input to the "ppp" parameter.
8) "misc.php" fails to verify input to the "desc" parameter.
9) "forumdisplay.php" fails to verify input to the "tpp" and "ascdesc" parameters.
10) "stats.php" fails to verify input to the "addon" parameter.
The vulnerabilities have been reported in version 1.8 SP 2.
Solution:
The vulnerabilities have been fixed in XMB 1.8 SP3 and XMB 1.9 Nexus BETA.
