CVE-2019-11753

Priority
Description
The Firefox installer allows Firefox to be installed to a custom user
writable location, leaving it unprotected from manipulation by unprivileged
users or malware. If the Mozilla Maintenance Service is manipulated to
update this unprotected location and the updated maintenance service in the
unprotected location has been altered, the altered maintenance service can
run with elevated privileges during the update process due to a lack of
integrity checks. This allows for privilege escalation if the executable
has been replaced locally. <br>*Note: This attack requires local system
access and only affects Windows. Other operating systems are not
affected.*. This vulnerability affects Firefox < 69, Firefox ESR < 60.9,
and Firefox ESR < 68.1.
