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
The absence of a CAA (Certification Authority Authorization) record in the DNS configuration of a domain can lead to security vulnerabilities. Without a CAA record, any Certificate Authority (CA) can issue SSL/TLS certificates for the domain, potentially allowing malicious actors to obtain unauthorized certificates. This can lead to man-in-the-middle attacks, where attackers can intercept and manipulate traffic between users and the website, compromising the confidentiality and integrity of the data.
Patches
To address this issue at scale for the large web sites and services, a CAA record should be added to their DNS configuration. This record specifies which CAs are authorized to issue certificates for the domain, thereby reducing the risk of unauthorized certificate issuance.
However, due to low-risk nature of uxlfoundation.org as an alternative mitigation we've hardened the internal procedure to make sure appropriate verification and usage of the certificates. No specific actions required from users.
