[原文]PHP remote file inclusion vulnerability in TRG News Script 3.0 allows remote attackers to execute arbitrary PHP code via the dir parameter to (1) article.php, (2) authorall.php, (3) comment.php, (4) display.php, or (5) displayall.php.
TRG News contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to 'article.php' not properly sanitizing user input supplied to the 'dir' variable. This may allow a remote 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.
