Description (CNA)
Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered. This vulnerability affects Firefox ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69.
Affected (CNA)
| Vendor / product | Versions |
|---|---|
| Mozilla / Firefox ESR | affected before 60.9 |
| Mozilla / Firefox ESR | affected before 68.1 |
| Mozilla / Firefox | affected before 69 |
