I appreciate any help you guys can give me. It’s a digital certificate used in Microsoft Outlook to sign the emails so that the receiver can be sure that the email has actually come from a legitimate person and has not been intercepted or altered by any other person. So, my doubts are: why my certificate is revoked? how can I solve this issue? Posted: (7 days ago) An outlook security certificate is also called S/MIME or email certificate. The SSL test also shows three different certificates, is it usual? Why is one of them as not trusted? It’s important to say the certificate is expired and this issue was happening even before the certificate expiration. I guess that’s why Avast is blocking my website. Accessing from PCs not running Avast, I had no problems.Īlso, I’ve tested the SSL through and it shows a certificate as not trusted. I tried to access the website from 3 different PCs running Avast and all of them happened the same thing.

After several months, the vulnerabilities were dealt with internally, but it was not until 9 March 2020 that a public patch had been deployed for both Avast and AVG AntiTrack, both of which share a similar core code.Īvast thanked the researcher for his findings, saying that the vulnerability has now been patched in Avast AntiTrack version 1.5.1.172 and AVG AntiTrack version 2.0.0.178. The third problem is a failure for AntiTrack to honor browser cipher suites or Forward Secrecy, a means to ensure session keys are not compromised.Įade disclosed the security problems to Avast on August 7, 2019. Even if a web server supports TLS 1.2, the software will ignore these settings and make connections to TLS 1.0 websites - and when it comes to browsers that have been configured to only reach websites supporting the higher standard, Avast's software should not ignore such direction. The second security problem outlined by the researcher is how Avast AntiTrack downgrades browser security protocols to TLS 1.0. In these cases, self-signed, malicious certificates may be missed, permitting attackers to launch MiTM attacks. captive portal browser HTTPS warning Upgraded the built-in certificate on the AP to the valid commercial certificate. The first issue has been caused by a failure to check the validity of certificates presented to end servers. However, a set of three security failures undermined these goals. A vulnerability impacting Avast and AVG AntiTrack privacy software opened up user PCs to Man-in-The-Middle attacks, browser session hijack, and data theft.ĭisclosed by David Eade on March 9, the security researcher said the security flaw, tracked as CVE-2020-8987, is a certification validation issue that affects Avast AntiTrack before 1.5.1.172 and AVG AntiTrack before 2.0.0.178.Īttackers do not need local access to trigger the vulnerability, and no special software configuration needs to be in place.Īvast's AntiTrack software is designed to block advertising trackers and to prevent "invasive" monitoring of your online habits.
