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.)

Severity

No CVSS data available.
