Maintainers recommend that this SIP message type is authenticated by default so that FreeSWITCH administrators do not need to be explicitly set the `auth-messages` parameter. Therefore, abuse can lead to spam and enable social engineering, phishing and similar attacks. Additionally, since no authentication is required, chat messages can be spoofed to appear to come from trusted entities. Abuse of this security issue allows attackers to send SIP MESSAGE messages to any SIP user agent that is registered with the server without requiring authentication.

Although this behaviour can be changed by setting the `auth-messages` parameter to `true`, it is not the default setting. MESSAGE requests are relayed to SIP user agents registered with the FreeSWITCH server without requiring any authentication. By default, SIP requests of the type MESSAGE (RFC 3428) are not authenticated in the affected versions of FreeSWITCH. Prior to version 1.10.7, FreeSWITCH does not authenticate SIP MESSAGE requests, leading to spam and message spoofing.

When following such a recommendation, a new parameter can be introduced to explicitly disable authentication.ДЇreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. SIP SUBSCRIBE messages should be authenticated by default so that FreeSWITCH administrators do not need to explicitly set the `auth-subscriptions` parameter.

Software upgrades do not update the configuration by default. Although this issue was fixed in version v1.10.6, installations upgraded to the fixed version of FreeSWITCH from an older version, may still be vulnerable if the configuration is not updated accordingly. For example, attackers may be able to monitor the status of target SIP extensions. This abuse poses privacy concerns and might lead to social engineering or similar attacks. Abuse of this security issue allows attackers to subscribe to user agent event notifications without the need to authenticate. By default, SIP requests of the type SUBSCRIBE are not authenticated in the affected versions of FreeSWITCH.
