Title: Contenido CMS Cross Site Scripting and Multiple Remote File Include Vulnerabilities
Severity: HIGH
Description:
Contenido CMS is a PHP-based content manger.
Since it fails to sufficiently sanitize user-supplied input, the application is prone to multiple input-validation vulnerabilities:
1. Contenido CMS is prone to multiple remote file-include vulnerabilities that affect the following scripts and parameters:
'backend_search.php': 'contenido_path'
'cronjobs/move_articles.php': 'cfg[path][contenido]'
'cronjobs/move_old_stats.php': 'cfg[path][contenido]'
'cronjobs/optimize_database.php': 'cfg[path][contenido]'
'cronjobs/run_newsletter_job.php': 'cfg[path][contenido]'
'cronjobs/send_reminder.php': 'cfg[path][contenido]'
'cronjobs/session_cleanup.php': 'cfg[path][contenido]'
'cronjobs/setfrontenduserstate.php': 'cfg[path][contenido]'
'includes/include.newsletter_jobs_subnav.php': 'cfg[path][templates]'
'plugins/content_allocation/includes/include.right_top.php': 'cfg[path][templates]'
'includes/include.newsletter_jobs_subnav.php': 'cfg[templates][right_top_blank]'
'includes/include.newsletter_jobs_subnav.php': 'cfg[path][contenido]'
'plugins/content_allocation/includes/include.right_top.php': 'cfg[path][contenido]'
'plugins/content_allocation/includes/include.right_top.php': 'cfg[path][templates]'
'plugins/content_allocation/includes/include.right_top.php': 'cfg[templates][right_top_blank]'
2. The application is prone to a cross-site scripting vulnerability that affects the 'contenido' parameter of the 'index.php' script.
An attacker can exploit these issues to execute malicious PHP code in the context of the webserver process. This may allow the attacker to compromise the application and the underlying system, execute script code in an unsuspecting user's browser, or steal cookie-based authentication credentials; other attacks are also possible.
These issues affect Contenido CMS 4.8.4; other versions may also be vulnerable.
Affected Products:
- Contenido Contenido 4.6.0
- Contenido Contenido 4.6.1
- Contenido Contenido 4.6.4
