CVE-2013-7449 is a vulnerability of currently unknown severity. The ssl_do_connect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.. EPSS estimates a 0.76% chance of exploitation in the next 30 days.
