[原文]PHP remote file inclusion vulnerability in Bookmark4U 2.0.0 and earlier allows remote attackers to include arbitrary PHP files via the include_prefix parameter in (1) inc/dbase.php, (2) inc/config.php, (3) inc/common.php, and (4) inc/function.php. NOTE: it has been reported that the inc directory is protected by a .htaccess file, so this issue only applies in certain environments or configurations.
Bookmark4U contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to inc/dbase.php not properly sanitizing user input supplied to the 'env[include_prefix]' variable. This may allow an attacker to include a file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
