Description

 IDA Pro Remote Debugger Server contains a flaw that may allow a malicious user to bypass password functionality. It is possible that the flaw may allow the execution of arbitrary code under the context of the user that started the debugger server resulting in a loss of integrity.

Classification

 Location: Remote / Network Access
Attack Type: Authentication Management
Impact: Loss of Integrity
Exploit: Exploit Private, Exploit Unknown
Disclosure: OSVDB Verified

Technical

 The IDA Pro Remote Debugger Server allows a user to specify a password for authentication by supplying the -P parameter. The vulnerability specifically exists in the the processor_request() function. This function is used for the initial packet exchange as well as subsequent requests. This function does not ensure that the remote user has authenticated prior to calling the perform_request() function. As such, attacker requests sent prior to authenticating will be processed normally.

It should be noted that the debugger server does not run as a service. It must be manually executed. Additionally, the remote debugger server can only handle one debugger session at a time. As such, this vulnerability can not be exploited while the debugger server is in use.

Solution

 DataRescue has released a patch to address this vulnerability.
Additionally, it is possible to correct the flaw by implementing the following workaround(s):
- The remote debugger server should not be left running when it is not in use.
- Access to the port used by the remote debugger server could be blocked with the use of a firewall.
