CVE-2020-8987 (GCVE-0-2020-8987)

Vulnerability from cvelistv5 – Published: 2020-03-09 16:38 – Updated: 2024-08-04 10:19

Summary

Avast AntiTrack before 1.5.1.172 and AVG Antitrack before 2.0.0.178 proxies traffic to HTTPS sites but does not validate certificates, and thus a man-in-the-middle can host a malicious website using a self-signed certificate. No special action necessary by the victim using AntiTrack with "Allow filtering of HTTPS traffic for tracking detection" enabled. (This is the default configuration.)
