Detailsinfo

A vulnerability, which was classified as critical, was found in matrix-appservice-irc 0.35.0 (Chat Software). Affected is some unknown processing of the component IRC Protocol Handler. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269.

This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

matrix-appservice-irc is an open source Node.js IRC bridge for Matrix. The Internet Relay Chat (IRC) protocol allows you to specify multiple modes in a single mode command. Due to a bug in the underlying matrix-org/node-irc library, affected versions of matrix-appservice-irc perform parsing of such modes incorrectly, potentially resulting in the wrong user being given permissions. Mode commands can only be executed by privileged users, so this can only be abused if an operator is tricked into running the command on behalf of an attacker. The vulnerability has been patched in matrix-appservice-irc 0.35.0. As a workaround users should refrain from entering mode commands suggested by untrusted users. Avoid using multiple modes in a single command.

The weakness was presented 09/14/2022 as GHSA-cq7q-5c67-w39w. The advisory is available at github.com. This vulnerability is traded as CVE-2022-39202 since 09/02/2022.
