Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Phpmyfaq/phpmyfaq, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Due to insufficient validation on the `contentLink` parameter, it is possible for unauthenticated users to inject HTML code to the page which might affect other users. _Also, requires that adding new FAQs is allowed for guests and that the admin doesn't check the content of a newly added FAQ._ ### PoC 1. Browse to ../phpmyfaq/index.php?action=add&cat=0 , enter `https://test.com?p=<h1>HTML_INJECTION</h1>` for the contentLink parameter. ![image](https://github.com/thorsten/phpMyFAQ/assets/63487456/4925d1ab-aa64-4781-8a44-f4c30cb8499c) 2. Verify the HTML injection by viewing the FAQ itself, “All categories” → “CategoryName” → ”QuestionName”. ![image](https://github.com/thorsten/phpMyFAQ/assets/63487456/54b077d8-fab4-4cb6-870c-f19fc25d8252) ### Impact Attackers can manipulate the appearance and functionality of web pages by injecting malicious HTML code. This can lead to various undesirable outcomes, such as defacing the website, redirecting users to malicious sites, or altering the content to deceive users. Additionally, unauthenticated HTML injection can compromise user privacy by displaying sensitive information or misleading content. It undermines the integrity of the application and erodes user trust, potentially resulting in loss of reputation and credibility.
