Description: Some vulnerabilities have been reported in Drupal, which can be exploited by malicious people to conduct cross-site request forgery attacks and to compromise a vulnerable system.
1) Input passed to unspecified parameters in install.php is not properly sanitised. This can be exploited to execute arbitrary code.
Successful exploitation of this vulnerability requires that the configured SQL server is not reachable.
2) A vulnerability is caused due to the application allowing users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to delete users by enticing a logged-in administrator to visit a malicious site.
The vulnerabilities are reported in the 5.x branch before 5.3.
Solution: Update to version 5.3.
