[c-nsp] https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snmp-x4LPhte Is vulnerability pre or post ACL?

[Drew Weaver]

Howdy,

I'm reviewing this vulnerability for IOS:

https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snmp-x4LPhte

In the advisory it doesn't seem to mention whether the code execution happens pre or post the application of the ACL?

Consider this example:

snmp-server community YourVerySecureCommunityString RO 60

I assume that the ACL blocking access to hosts other than the NMS would be enough to prevent this from being super widely exploitable but its IOS so I am thinking in IOS terms.

Anyone have any details on that?

Thanks,
-Drew
