Some vulnerabilities have been in reported in OneCMS, which can be exploited by malicious people to conduct SQL injection attacks or by malicious users to compromise a vulnerable system.

1) Input passed to the "username" parameter in a_login.php, the "abc" parameter in userreviews.php, and to the "user" parameter in staff.php is not properly sanitised before being used in SQL queries. This can be exploited to conduct SQL injection attacks.

Successful exploitation allows to bypass the login mechanism and to retrieve e.g. the administrator's username and password hash, but may require "magic_quotes_gpc" to be deactivated.

2) The type of uploaded files is not correctly verified. This can be exploited to e.g. upload and execute arbitrary PHP code.

The vulnerabilities are reported in version 2.4. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised and verified.
