Some vulnerabilities have been reported in Oracle Secure Backup, which can be exploited by malicious people to conduct cross-site scripting attacks, cross-site request forgery attacks, and compromise a vulnerable system.

1) Input passed via the "mode" parameter to login.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. add an administrative user by tricking a logged in administrator into visiting a malicious web site.

3) Input passed via the "username" parameter to common.php is not properly verified in the "validate_login()" function before being used. This can be exploited to inject and execute arbitrary shell commands.

The vulnerabilities are reported in version 10.3.0.3.0. Other versions may also be affected.
