CVE-2025-8119: Widzialni Pad CMS CSRF Vulnerability

CVE-2025-8119 Overview

CVE-2025-8119 is a Cross-Site Request Forgery (CSRF) vulnerability affecting PAD CMS, a content management system developed by Widzialni. The flaw resides in the password reset functionality and allows an attacker to change an authenticated user's password without consent. When a logged-in victim visits an attacker-controlled page, the browser automatically issues a forged POST request that updates the account password to a value chosen by the attacker.

The issue affects all three product templates: www, bip, and www+bip. PAD CMS has reached End-Of-Life status, and the vendor has confirmed that no patches will be released for this vulnerability.

Critical Impact
Successful exploitation lets an attacker take over any authenticated PAD CMS account, including administrative accounts, by tricking the user into visiting a malicious page.

Affected Products

Widzialni PAD CMS - www template (all versions)
Widzialni PAD CMS - bip template (all versions)
Widzialni PAD CMS - www+bip template (all versions)

Technical Details for CVE-2025-8119

Vulnerability Analysis

The vulnerability is a classic Cross-Site Request Forgery weakness classified under [CWE-352]. PAD CMS accepts password change requests through a POST endpoint without validating a per-session anti-CSRF token or verifying the request origin. Any authenticated session cookie present in the victim's browser is automatically attached to the outbound request, allowing the server to treat the forged submission as legitimate.

Exploitation requires only that the victim be logged into PAD CMS and visit an attacker-controlled page in the same browser. No knowledge of the current password is needed. Because the attacker sets the new password, the outcome is full account takeover of the targeted user, including administrators managing the CMS backend.

See the CERT.PL Analysis on CVE-2025-7063 for related technical context on PAD CMS advisories.

Root Cause

The root cause is the absence of state-changing request protections on the password reset endpoint. PAD CMS does not enforce a synchronizer token, does not check the Origin or Referer headers, and does not set the session cookie with the SameSite attribute. These missing controls allow cross-origin POST submissions carrying the victim's session to succeed.

Attack Vector

The attack is network-based and requires user interaction. An attacker hosts an HTML page containing an auto-submitting form or a fetch() call that targets the PAD CMS password change endpoint with attacker-chosen credentials. When a logged-in victim loads the page, the browser sends the POST request with valid session cookies, and the CMS updates the password. The attacker then logs in with the new credentials.

No verified public exploit code is available. The vulnerability mechanism is described in prose based on the CERT.PL advisory linked above.

Detection Methods for CVE-2025-8119

Indicators of Compromise

Unexpected password change events in PAD CMS application logs, particularly for administrative accounts.
HTTP POST requests to the password reset endpoint containing Referer or Origin headers pointing to external domains.
Successful logins from unusual IP addresses or geolocations shortly after a password change event.
User reports of being locked out of PAD CMS accounts without initiating a password change.

Detection Strategies

Inspect web server access logs for POST requests to the password change URL where the Referer header is missing or does not match the application's own domain.
Correlate password change events with the account's typical activity patterns to flag anomalous resets.
Alert on password change events followed by immediate session creation from a different IP address.

Monitoring Recommendations

Enable verbose application-level auditing for authentication and account management endpoints.
Forward web and application logs to a centralized SIEM for correlation and long-term retention.
Track administrative account changes and require out-of-band notification for password resets.

How to Mitigate CVE-2025-8119

Immediate Actions Required

Migrate away from PAD CMS to a supported CMS platform, as the product is End-Of-Life and will not receive fixes.
Restrict access to PAD CMS administrative interfaces to trusted IP ranges or a VPN.
Force password rotation for all PAD CMS users and audit accounts for unauthorized changes.
Instruct administrators to log out of PAD CMS when not actively using it and to avoid browsing untrusted sites in the same session.

Patch Information

No patch is available. The vendor (Widzialni) has declared PAD CMS End-Of-Life and stated that no security fixes will be published for this vulnerability. Migration to a maintained CMS is the only long-term remediation.

Workarounds

Deploy a Web Application Firewall (WAF) rule that blocks POST requests to the password change endpoint when the Referer or Origin header does not match the PAD CMS domain.
Configure the reverse proxy to inject or enforce SameSite=Strict on the PAD CMS session cookie to prevent cross-site cookie attachment.
Isolate PAD CMS administrator browsing to a dedicated browser profile or hardened workstation used only for CMS management.
Require administrators to use a separate authenticated channel for password changes, bypassing the vulnerable web workflow where feasible.

bash

# Example nginx configuration enforcing Referer validation on the password endpoint
location /password/reset {
    if ($http_referer !~* "^https://cms\.example\.com/") {
        return 403;
    }
    proxy_pass http://padcms_backend;
    proxy_cookie_flags ~ SameSite=Strict Secure HttpOnly;
