Title
Cotonti Siena 0.9.26 Stored XSS via PFS Module ntitle Parameter
Summary
Cotonti Siena 0.9.26 and earlier contains a stored cross-site scripting vulnerability that allows authenticated users with PFS access to inject arbitrary script payloads by supplying malicious HTML in the ntitle parameter processed through the TXT filter in pfs.main.php. Attackers can create a folder with a crafted title containing script tags that are stored unescaped in the database and execute in the browser of any user who views the folder listing, including administrators.

Title
Cotonti Siena 0.9.26 CSRF via admin.php Config Update Endpoint
Summary
Cotonti Siena 0.9.26 and earlier contains a cross-site request forgery vulnerability that allows unauthenticated attackers to modify administrator configuration by tricking a logged-in administrator into submitting a forged POST request to the admin.php config update handler, which never invokes the application's CSRF validation function. Attackers can disable the PFS module's file extension whitelist by setting pfsfilecheck to 0, enabling any user with PFS access to upload and execute arbitrary PHP files on the server.

Title
Cotonti stored XSS via PFS folder title
Summary
Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to stored Cross-Site Scripting in the Personal File Storage (PFS) module. A folder title (pff_title) is imported with the 'TXT' filter, which does not strip or encode HTML (the tag check in cot_import is disabled), so an authenticated user can store HTML/JavaScript in a folder title.

Title
Cotonti CSRF in PFS folder edit allows unauthorized folder modification
Summary
Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the Personal File Storage (PFS) module. In modules/pfs/inc/pfs.editfolder.php, the folder update action ('a=update') updates folder metadata (title, description, public/gallery flags) without calling cot_check_xg to validate the anti-CSRF token.

Summary
Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the administration configuration handler. In system/admin/admin.config.php, the configuration update action ('a=update') processes POST data via cot_config_update_options without calling cot_check_xg to validate the anti-CSRF token (the 'x' parameter), unlike other admin handlers (e.g. admin.structure.php, admin.cache.php).

In plugins/comments/controllers/actions/CreateAction.php, a POST parameter obtained via (trim-only sanitization) is passed to with no restriction, reachable by any member with write access to comments (the default setting in plugins/comments/comments.setup.php).

Title
Cotonti Siena 0.9.26 CSRF via admin.php Config Update Endpoint
Summary
Cotonti Siena 0.9.26 and earlier contains a cross-site request forgery vulnerability that allows unauthenticated attackers to modify administrator configuration by tricking a logged-in administrator into submitting a forged POST request to the admin.php config update handler, which never invokes the application's CSRF validation function. Attackers can disable the PFS module's file extension whitelist by setting pfsfilecheck to 0, enabling any user with PFS access to upload and execute arbitrary PHP files on the server.

Title
Cotonti stored XSS via PFS folder title
Summary
Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to stored Cross-Site Scripting in the Personal File Storage (PFS) module. A folder title (pff_title) is imported with the 'TXT' filter, which does not strip or encode HTML (the tag check in cot_import is disabled), so an authenticated user can store HTML/JavaScript in a folder title.

Title
Cotonti CSRF in admin.config.php allows unauthorized configuration changes
Summary
Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the administration configuration handler. In system/admin/admin.config.php, the configuration update action ('a=update') processes POST data via cot_config_update_options without calling cot_check_xg to validate the anti-CSRF token (the 'x' parameter), unlike other admin handlers (e.g. admin.structure.php, admin.cache.php).
