Description
CamaleonCMS contains a stored cross-site scripting vulnerability in the cama_contact_form plugin that allows low-privileged authenticated attackers to inject arbitrary HTML by submitting unsanitized content to the before_html field through the contact form edit endpoint, which lacks proper authorization controls. Attackers can persist malicious script payloads into the database that execute in victims' browsers when the contact form loads, enabling cookie theft, forged authenticated requests against the admin interface, and session takeover of viewing users.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in the CamaleonCMS cama_contact_form plugin. Low-privileged authenticated attackers can inject arbitrary HTML by submitting unsanitized content to the before_html field through the contact form edit endpoint. The lack of proper authorization controls allows this injection, which is then stored in the database and executed in victims' browsers when the contact form loads.

Detection Guidance

To detect this vulnerability, inspect the CamaleonCMS cama_contact_form plugin versions 2.9.1 and below. Check for unsanitized 'before_html' field submissions in contact form edit endpoints. Look for stored malicious scripts in the database that execute when forms load.

Impact Analysis

Attackers can exploit this to steal cookies, forge authenticated requests against the admin interface, and take over sessions of users viewing the contact form. This could lead to unauthorized access to sensitive data or actions on behalf of users.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive user data, such as cookies or session tokens, which may contain personally identifiable information (PII). This could result in violations of GDPR and HIPAA if exploited, as it enables attackers to steal data or forge authenticated requests, compromising data confidentiality and integrity.

Mitigation Strategies

Immediately update the cama_contact_form plugin to a version beyond 2.9.1. Implement input sanitization for the 'before_html' field. Restrict access to the contact form edit endpoint to authorized users only.
