[原文]login.php in myBloggie 2.1.3 beta and earlier allows remote attackers to bypass a whitelist regular expression and conduct SQL injection attacks via a username parameter with SQL after a null character, which causes the whitelist check to succeed but injects the SQL into a query string, a different vulnerability than CVE-2005-2838. NOTE: it is possible that this is actually a bug in PHP code, in which case this should not be treated as a myBloggie vulnerability.
myBloggie login.php username Variable Null Character SQL Injection
Remote / Network Access
Loss of Confidentiality,
Loss of Integrity
myBloggie contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the login.php script not properly sanitizing user-supplied input beginning with a null character to the 'username' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
