Description
A mechanism to bypass Content Security Policy (CSP) protections on sites that have a "script-src" policy of "'strict-dynamic'". If a target website contains an HTML injection flaw an attacker could inject a reference to a copy of the "require.js" library that is part of Firefox's Developer Tools, and then use a known technique using that library to bypass the CSP restrictions on executing injected scripts. This vulnerability affects Firefox < 60.
Affected configurations
• canonical ubuntu linux 14.04
• canonical ubuntu linux 16.04
• canonical ubuntu linux 17.10
• canonical ubuntu linux 18.04
• mozilla firefox (< 60.0)
