CVE-2016-2087
Exploit Found
Directory traversal vulnerability in the client in HexChat 2.11.0 allows remote IRC servers to read or modify arbitrary files via a .. (dot dot) in the server name.
Severity: HIGH
6.5
CVSS
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.
Severity: MEDIUM
