Network Error Logging helps web server operators detect operational problems in
real-time to provide fast and reliable services. This paper analyses Network
Error Logging from two angles. Firstly, this paper overviews Network Error
Logging from the data protection view. The ePrivacy Directive requires consent
for non-essential access to the end devices. Nevertheless, the Network Error
Logging design does not allow limiting the tracking to consenting users. Other
issues lay in GDPR requirements for transparency and the obligations in the
contract between controllers and processors of personal data. Secondly, this
paper explains Network Error Logging exploitations to deploy long-time trackers
to the victim devices. Even though users should be able to disable Network Error
Logging, it is not clear how to do so. Web server operators can mitigate the
attack by configuring servers to preventively remove policies that adversaries
might have added.
