Test ID:1.3.6.1.4.1.25623.1.0.9999993
Category:General
Title:Asterisk PBX SIP Service Guest Access Enabled
Summary:Asterisk PBX SIP service guest access is enabled.
Description:Summary:
Asterisk PBX SIP service guest access is enabled.

Vulnerability Insight:
The SIP service is accepting SIP peers to use the proxy server
as guest users. Unauthenticated users can use the proxy without supplying the required
'more secure' authentication.

Guest access is enabled by default if 'allowguest=no' is not set in 'sip.conf'. Guest peers use
the context defined under the general section and the restrictions set in the Asterisk config
files.

Solution:
If guest access is not needed, disable it by setting
'allowguest=no' in the sip.conf file.

CVSS Score:
3.5
