Description:
Some vulnerabilities have been discovered in H2O-CMS, which can be exploited by malicious people to bypass certain security restrictions or by malicious users to compromise a vulnerable system.
1) A vulnerability is caused due to the application allowing access to the admin interface by checking if specific cookies exist. This can be exploited to gain administrative access to the application by creating the cookies "admin" with the value "1", "id" with the value "1" and "user" with the value "admin".
2) Input passed to the "site_title", "login_stat", "colour", "menu_home", "user_menu_news_posting", "user_menu_news_manager", "user_menu_messagebox", "news_posting_auto_approval", "bottom_text", "db_name", "db_username", "db_password" and "db_server" parameters in SaveConfig.php is not properly sanitised before being written to includes/config.php. This can be exploited to execute arbitrary PHP code.
Successful exploitation of this vulnerability requires administrative privileges (see vulnerability #1).
These vulnerabilities are confirmed in version 3.4. Other versions may also be affected.
