CVE-2020-13645

Disclosure Date: May 28, 2020 •
CVE-2020-13645 CVSS v3 Base Score: 6.5
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server’s TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host.
