The AMI Originate action can allow a remote user to specify information that can be used to execute shell commands on the system hosting Asterisk. This can result in an unwanted escalation of permissions, as the Originate action, which requires the "originate" class authorization, can be used to perform actions that would typically require the "system" class authorization. Previous attempts to prevent this permission escalation (AST-2011-006, AST-2012-004) have sought to do so by inspecting the names of applications and functions passed in with the Originate action and, if those applications/functions matched a predefined set of values, rejecting the command if the user lacked the "system" class authorization. As noted by IBM X-Force Research, the "ExternalIVR" application is not listed in the predefined set of values. The solution for this particular vulnerability is to include the "ExternalIVR" application in the set of defined applications/functions that require "system" class authorization. Unfortunately, the approach of inspecting fields in the Originate action against known applications/functions has a significant flaw. The predefined set of values can be bypassed by creative use of the Originate action or by certain dialplan configurations, which is beyond the ability of Asterisk to analyze at run-time. Attempting to work around these scenarios would result in severely restricting the applications or functions and prevent their usage for legitimate means. As such, any additional security vulnerabilities, where an application/function that would normally require the "system" class authorization can be executed by users with the "originate" class authorization, will not be addressed. Instead, the README-SERIOUSLY.bestpractices.txt file has been updated to reflect that the AMI Originate action can result in commands requiring the "system" class authorization to be executed. Proper system configuration can limit the impact of such scenarios. (closes issue ASTERISK-20132) Reported by: Zubair Ashraf of IBM X-Force Research ........

/* In order to understand what the heck is going on with the
|
|
* mansession_session and mansession structs, we need to have a bit of a history
|
|
* lesson.
|
|
*
|
|
* In the beginning, there was the mansession. The mansession contained data that was
|
|
* intrinsic to a manager session, such as the time that it started, the name of the logged-in
|
|
* user, etc. In addition to these parameters were the f and fd parameters. For typical manager
|
|
* sessions, these were used to represent the TCP socket over which the AMI session was taking
|
|
* place. It makes perfect sense for these fields to be a part of the session-specific data since
|
|
* the session actually defines this information.
|
|
*
|
|
* Then came the HTTP AMI sessions. With these, the f and fd fields need to be opened and closed
|
|
* for every single action that occurs. Thus the f and fd fields aren't really specific to the session
|
|
* but rather to the action that is being executed. Because a single session may execute many commands
|
|
* at once, some sort of safety needed to be added in order to be sure that we did not end up with fd
|
|
* leaks from one action overwriting the f and fd fields used by a previous action before the previous action
|
|
* has had a chance to properly close its handles.
|
|
*
|
|
* The initial idea to solve this was to use thread synchronization, but this prevented multiple actions
|
|
* from being run at the same time in a single session. Some manager actions may block for a long time, thus
|
|
* creating a large queue of actions to execute. In addition, this fix did not address the basic architectural
|
|
* issue that for HTTP manager sessions, the f and fd variables are not really a part of the session, but are
|
|
* part of the action instead.
|
|
*
|
|
* The new idea was to create a structure on the stack for each HTTP Manager action. This structure would
|
|
* contain the action-specific information, such as which file to write to. In order to maintain expectations
|
|
* of action handlers and not have to change the public API of the manager code, we would need to name this
|
|
* new stacked structure 'mansession' and contain within it the old mansession struct that we used to use.
|
|
* We renamed the old mansession struct 'mansession_session' to hopefully convey that what is in this structure
|
|
* is session-specific data. The structure that it is wrapped in, called a 'mansession' really contains action-specific
|
|
* data.

* entity named from the variable ajaxobjtype, default to "generic"

|
