[原文]Simplog 0.9.1 might allow remote attackers to execute arbitrary SQL commands or trigger SQL error messages via invalid (1) pid, (2) blogid, (3) cid, or (4) m parameters to archive.php, or the (5) blogid parameter to blogadmin.php.
Simplog contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the archive.php script not properly sanitizing user-supplied input to the 'pid' and 'cid' variables. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to version 0.9.2 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
