WordPress mbstring extension security bypass
|wordpress-mbstring-security-bypass (31297)||Medium Risk|
WordPress could allow a remote attacker to bypass security restrictions, caused by a vulnerability in different charset trackbacks. If PHP's mbstring extension is enabled, a remote attacker could bypass SQL parameter escaping and perform SQL injection attacks which could allow the attacker to view, add, modify or delete information in the back-end database.
Upgrade to the latest version of WordPress (2.06 or later), available from the WordPress Web site. See References.
