CVE-2025-69237: Raytha CMS Stored XSS Vulnerability

CVE-2025-69237 Overview

CVE-2025-69237 is a stored cross-site scripting (XSS) vulnerability in Raytha CMS. The flaw resides in the FieldValues[0].Value parameter within the page creation functionality. An authenticated attacker with content creation permissions can inject arbitrary HTML and JavaScript that executes when other users view the affected page. The vulnerability is tracked under CWE-79 (Improper Neutralization of Input During Web Page Generation). Raytha addressed the issue in version 1.4.6.

Critical Impact

Authenticated attackers can persist malicious scripts in CMS pages, enabling session theft, credential harvesting, and unauthorized actions against administrators and visitors.

Affected Products

• Raytha CMS versions prior to 1.4.6
• Deployments exposing authenticated page creation workflows
• Any Raytha instance where low-privilege content authors are permitted

Technical Details for CVE-2025-69237

Vulnerability Analysis

The vulnerability stems from insufficient output encoding of user-supplied field values in Raytha's page creation interface. When an authenticated user submits content through the FieldValues[0].Value parameter, the application stores the raw input and later renders it without proper neutralization. Any HTML or JavaScript payload persists in the database and executes in the browser of every visitor who loads the affected page.

This is a stored XSS variant, which is more impactful than reflected XSS because the payload reaches users without requiring per-victim crafted links. The attack requires authenticated access with permission to create or edit content. In multi-tenant or community-driven CMS deployments, this barrier is low.

Root Cause

The root cause is missing or inadequate HTML encoding of field values during template rendering. Raytha's page creation handler trusts authenticated user input and writes it directly into the rendered HTML context. The framework does not apply context-aware escaping to the FieldValues[0].Value parameter before persistence or display.

Attack Vector

An attacker first authenticates to Raytha with an account holding content creation rights. The attacker then creates or edits a page and submits a payload such as a <script> tag or an event-handler attribute through the FieldValues[0].Value field. When an administrator, editor, or site visitor navigates to the page, the injected script runs in their browser session under the Raytha origin. The script can exfiltrate cookies, perform CSRF actions, or pivot to administrative functions if a privileged user views the page.

The vulnerability mechanism is documented in the CERT.pl advisory covering related Raytha issues. No public proof-of-concept code has been verified.

Detection Methods for CVE-2025-69237

Indicators of Compromise

• Page records containing <script>, javascript:, or HTML event handlers such as onerror= and onload= within FieldValues columns
• Unexpected outbound requests from administrator browsers to unfamiliar domains shortly after visiting CMS pages
• New or modified content authored by low-privilege accounts that includes raw HTML markup in stored fields
• Session token reuse from anomalous IP addresses following administrator visits to attacker-authored pages

Detection Strategies

• Query the Raytha database for stored field values matching XSS-indicative patterns such as <script, onerror=, or onfocus=
• Inspect web server access logs for POST requests to page creation endpoints containing encoded angle brackets or script tags in body parameters
• Enable Content Security Policy (CSP) report-only mode to surface inline script violations originating from CMS-rendered pages
• Correlate authentication events for content authors with subsequent administrator page views to identify potential session compromise

Monitoring Recommendations

• Audit content creation activity from non-administrator accounts on a recurring basis
• Forward Raytha application and web server logs to a centralized analytics platform for retention and correlation
• Monitor for newly registered low-privilege accounts that immediately attempt to create or edit pages
• Alert on CSP violation reports referencing inline scripts within CMS page paths

How to Mitigate CVE-2025-69237

Immediate Actions Required

• Upgrade Raytha CMS to version 1.4.6 or later, which contains the official fix
• Review existing pages for previously injected payloads and sanitize stored FieldValues content
• Restrict content creation permissions to trusted accounts and disable self-registration where feasible
• Rotate session secrets and force re-authentication for administrative users after patching

Patch Information

The vendor resolved the issue in Raytha version 1.4.6. The patch introduces proper output encoding for the FieldValues[0].Value parameter and related field rendering paths. Administrators should consult the Raytha project site for upgrade instructions and release notes.

Workarounds

• Limit page creation and editing rights to a minimal set of trusted administrators until the upgrade is applied
• Deploy a web application firewall rule that blocks <script> tags and dangerous event handlers in FieldValues POST parameters
• Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to known origins
• Require multi-factor authentication for all accounts with content authoring privileges to reduce account takeover risk

# Example CSP header to mitigate inline script execution
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'";
