Cisco ASA Input Validation File Injection Vulnerability

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCva38556

Below is my device details:

This platform has an ASA5585-SSP-20 VPN Premium license.
Serial Number: JAD173301HM

Cisco Adaptive Security Appliance Software Version 8.2(5)49 <context>
Device Manager Version 7.1(2)

How do I check if my ASA is expose to this bug?

It looks like this bug is listed to only affect 9.1(6.10), however, you are running a pretty old version of code that has tons of other vulnerabilities. There is a 8.2(5)59 interim update that you should consider moving to. 

With that being said, it is a good idea to reach out to TAC and confirm 100% that your device and version of code is not affected by this specific defect. 

I hope this helps!

Thank you for rating helpful posts!

+1 for upgrade recommendation. Still running 8.2.x in 2016 is not a good idea.

Update: 

You ask an excellent question, but the confusion is well apparent, as seen in another thread:

https://supportforums.cisco.com/discussion/13169031/cscva38556-cve-id-cve-2016-6461-known-fixed-releases

With that said, 9.5(3)6 was released on the 13th of December, it contains the fix for Bug CSCva38556, for the -x series models of the ASA:

(So, like others, I am confused why this version wasn't listed as "affected" by the bug, if it is going to receive the "fix" for the bug. )

I re-check the bug to be sure, on 12/15/2016 (today), and it only lists 9.1(6)10 as a known  affected release. (if so, then why is 9.5(3) receiving a "fix"?)

Update: 9.17(12) was released on 12/21/2016.

It resolves the issue for the X-series as well as the older series devices.
