Some vulnerabilities have been discovered in phpMyAdmin, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to bypass security restrictions.
1) Input passed to the "Table comments" form field parameter in tbl_create.php and tbl_properties_operations.php is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the database containing the table is viewed.
Successful exploitation requires valid user credentials.
2) Input passed in the "X-Forwarded-For", "X-Forwarded", "Forwarded-For", "Forwarded", "Via", "X-Coming-From", and "Coming-From" HTTP headers is trusted from all clients. This can be exploited to bypass IP address checks by connecting to phpMyAdmin and sending arbitrary values in one of the listed headers.
The vulnerabilities are confirmed in version 2.9.1. Other versions may also be affected.
Solution: Update to version 220.127.116.11.
