Asterisk Project Security Advisory - AST-2008-003 +------------------------------------------------------------------------+ \| Product \| Asterisk \| \|--------------------+---------------------------------------------------\| \| Summary \| Unauthenticated calls allowed from SIP channel \| \| \| driver \| \|--------------------+---------------------------------------------------\| \| Nature of Advisory \| Authentication Bypass \| \|--------------------+---------------------------------------------------\| \| Susceptibility \| Remote Unauthenticated Sessions \| \|--------------------+---------------------------------------------------\| \| Severity \| Major \| \|--------------------+---------------------------------------------------\| \| Exploits Known \| No \| \|--------------------+---------------------------------------------------\| \| Reported On \| March 12, 2008 \| \|--------------------+---------------------------------------------------\| \| Reported By \| Jason Parker <jparker@digium.com> \| \|--------------------+---------------------------------------------------\| \| Posted On \| March 18, 2008 \| \|--------------------+---------------------------------------------------\| \| Last Updated On \| March 18, 2008 \| \|--------------------+---------------------------------------------------\| \| Advisory Contact \| Jason Parker <jparker@digium.com> \| \|--------------------+---------------------------------------------------\| \| CVE Name \| CVE-2008-1332 \| +------------------------------------------------------------------------+ +------------------------------------------------------------------------+ \| Description \| Unauthenticated calls can be made via the SIP channel \| \| \| driver using an invalid From header. This acts similarly \| \| \| to the SIP configuration option 'allowguest=yes', in \| \| \| that calls with a specially crafted From header would be \| \| \| sent to the PBX in the context specified in the general \| \| \| section of sip.conf. \| +------------------------------------------------------------------------+ +------------------------------------------------------------------------+ \| Resolution \| A fix has been added which checks for the option \| \| \| 'allowguest' to be enabled before determining that \| \| \| authentication is not required. \| \| \| \| \| \| As a workaround, modify the context in the general \| \| \| section of sip.conf to point to a non-trusted location \| \| \| (example: a non-existent context, or a context that does \| \| \| nothing but hang up the call). \| +------------------------------------------------------------------------+ +------------------------------------------------------------------------+ \| Affected Versions \| \|------------------------------------------------------------------------\| \| Product \| Release \| \| \| \| Series \| \| \|------------------------------+---------+-------------------------------\| \| Asterisk Open Source \| 1.0.x \| All versions \| \|------------------------------+---------+-------------------------------\| \| Asterisk Open Source \| 1.2.x \| All versions prior to 1.2.27 \| \|------------------------------+---------+-------------------------------\| \| Asterisk Open Source \| 1.4.x \| All versions prior to \| \| \| \| 1.4.18.1 and 1.4.19-rc3 \| \|------------------------------+---------+-------------------------------\| \| Asterisk Business Edition \| A.x.x \| All versions \| \|------------------------------+---------+-------------------------------\| \| Asterisk Business Edition \| B.x.x \| All versions prior to B.2.5.1 \| \|------------------------------+---------+-------------------------------\| \| Asterisk Business Edition \| C.x.x \| All versions prior to C.1.6.2 \| \|------------------------------+---------+-------------------------------\| \| AsteriskNOW \| 1.0.x \| All versions prior to 1.0.2 \| \|------------------------------+---------+-------------------------------\| \| Asterisk Appliance Developer \| SVN \| All versions prior to \| \| Kit \| \| Asterisk 1.4 revision 109393 \| \|------------------------------+---------+-------------------------------\| \| s800i (Asterisk Appliance) \| 1.0.x \| All versions prior to 1.1.0.2 \| +------------------------------------------------------------------------+ +------------------------------------------------------------------------+ \| Corrected In \| \|------------------------------------------------------------------------\| \| Product \| Release \| \|---------------+--------------------------------------------------------\| \| Asterisk Open \| 1.2.27, 1.4.18.1/1.4.19-rc3, available from \| \| Source \| http://downloads.digium.com/pub/telephony/asterisk \| \|---------------+--------------------------------------------------------\| \| Asterisk \| B.2.5.1, C.1.6.2 \| \| Business \| \| \| Edition \| \| \|---------------+--------------------------------------------------------\| \| AsteriskNOW \| 1.0.2, available from http://www.asterisknow.org/ \| \| \| \| \| \| Current users can update using the system update \| \| \| feature in the appliance control panel. \| \|---------------+--------------------------------------------------------\| \| Asterisk \| Asterisk 1.4 revision 109393.
