[原文]Eval injection vulnerability in index.php in ClanSys 1.1 allows remote attackers to execute arbitrary PHP code via PHP code in the page parameter, as demonstrated by using an "include" statement that is injected into the eval statement. NOTE: this issue has been described as file inclusion by some sources, but that is just one attack; the primary vulnerability is eval injection.
Clansys contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to index.php not properly sanitizing user input supplied to the 'page' 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.
