Cannot be added into exclusion list

Recommended Posts

Anti-Exploit is blocking our Barracuda SSL/VPN client (java-based) from loading. 

Error attempting to add to exclusion list:  "Selected threat does not contain a valid payload checksum, it cannot be added into exclusion list."


Is there a way we can add an exclusion for this (other than simply turning off the Java shield, completely).


Log files are attached.


Anti-Exploit version is

Welcome to the forum.


Unfortunately there's no way to currently white-list this behavior. Allowing a browser-based Java instance to execute system commands is about as bad as an idea as it gets.


We are working on a way to allow this within internal/private IP ranges but it is not yet ready. In the meantime feel free to deactivate the Java shield if you absolutely need this functionality (which I would be very wary of).


I'll update this thread when we have a version ready to whitelist internal/private IP ranges.


PS: moving to the ForBusiness support section.

Hello esherret,

1.09 is available for testing with the new setting Pedro mentioned in this posts. You can find it here:




The setting will be under advanced settings>Java> Allow insecure java Operation on internal ranges. If you test it and it fixes the issue, please let us know so we can get some feedback on this!


Thank you,
