CVE-2020-15078 - Sophos SSL VPN Client / OpenVPN

IngoKaspers_URSUSIT

Good Day everyone!

May I ask a question about the Sophos SSL VPN Client.

One of our customer is using a vulnerability scan tool (Qualys) and reporting is showing me entries from clients with installed Sophos SSL VPN Client.

Firewall Version is SFOS 18.0.5 MR-5-Build586.

When i am downloading the SSL VPN Client from User Portal - OpenVPN Version is 2.3.8.

Any chance for a new Update or do we have to change all VPN Users to Sophos Connect?

    Sophos Connect uses 2.5.0. Therefore it would be affected as well, but i highly recommend to open a support case. I would assume, this is already addressed by a patch within the system without updating the version. Those vulnerability scan tools simply check versions and not exploiting the software. Therefore they do not detect the actual state.
