[原文]Multiple SQL injection vulnerabilities in Gregarius 0.5.2 allow remote attackers to execute arbitrary SQL commands via the (1) folder parameter to feed.php or (2) rss_query parameter to search.php.
Gregarius contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the feed.php script not properly sanitizing user-supplied input to the 'folder' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to version 0.5.3 svn or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
