Description

Impact

uxlfoundation.org website is a static landing page, features a clean, minimalist layout with basic information about the foundation, some useful links to specifications, github repositories, videos, etc. It leverages GitHub Pages as a hosting engine. UXL landing page is considered low risk by default because of:

  • No user interactions
  • Static Content with no logins or databases
  • No external integrations with 3rd parties such as APIs

Clickjacking, also known as a User Interface (UI) redress attack, is a vulnerability where a web user is tricked into clicking on something different from what they perceive, potentially revealing confidential information or taking control of their computer. This vulnerability affects the web server at https://uxlfoundation.org/ and can potentially lead to cross-site request forgery (CSRF) attacks, where malicious sites can interact with functions on other websites.

Patches

Although enabling Content Security Policy (CSPs) for the website would be the default mitigation approach, GitHub Pages doesn't support such a configuration. Thus, alternative mitigation was applied, resulting in enforced Content Security Policy is now part of website loading. No specific actions required from users.

Credits

We would like to thank Kunal Mhaske for identifying and reporting this vulnerability. Their diligent work and responsible disclosure have been invaluable in helping to protect UXL community.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
