Description:
Some vulnerabilities have been reported in Zeroboard, which can be exploited by malicious people to compromise a vulnerable system, conduct cross-site scripting attacks and disclose sensitive information.
1) Input passed to the "dir" parameter in "error.php", "login.php", "setup.php", "ask_password.php" and "print_category.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 vulnerability has been reported in version 4.1pl5 and prior.
2) Input passed to the "_zb_path" parameter in "_head.php" and "outlogin.php", and "dir" parameter in "write.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Successful exploitation requires that "register_globals" is enabled.
The vulnerability has been reported in version 4.1pl5 and prior.
3) Input passed to the "sn1", "page", and "year" parameters in "zboard.php" and the "filename" parameter in "view_image.php" is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.
4) Input passed to the "keyword" parameter isn't properly sanitised before being used in a "preg_replace()" call. This can be exploited to execute arbitrary PHP code.
The vulnerability has been reported in version 4.1pl2 through 4.1pl5.
Solution:
Update to version 4.1pl6 or later.
