CVE-2022-28352 (GCVE-0-2022-28352)
Vulnerability from nvd – Published: 2022-04-02 16:36 – Updated: 2024-08-03 05:56
VLAI
Summary
WeeChat (aka Wee Enhanced Environment for Chat) 3.2 to 3.4 before 3.4.1 does not properly verify the TLS certificate of the server, after certain GnuTLS options are changed, which allows man-in-the-middle attackers to spoof a TLS chat server via an arbitrary certificate. NOTE: this only affects situations where weechat.network.gnutls_ca_system or weechat.network.gnutls_ca_user is changed without a WeeChat restart.

CVE-2022-28352 (GCVE-0-2022-28352)
Vulnerability from cvelistv5 – Published: 2022-04-02 16:36 – Updated: 2024-08-03 05:56
VLAI
Summary
WeeChat (aka Wee Enhanced Environment for Chat) 3.2 to 3.4 before 3.4.1 does not properly verify the TLS certificate of the server, after certain GnuTLS options are changed, which allows man-in-the-middle attackers to spoof a TLS chat server via an arbitrary certificate. NOTE: this only affects situations where weechat.network.gnutls_ca_system or weechat.network.gnutls_ca_user is changed without a WeeChat restart.
