SafeSquid Crash when uploading custom config.xml file.
Posted: Thu Jul 14, 2022 3:23 pm
When uploading a custom config.xml file into the safesquid proxy server via SafeSquid’s web interface option “Upload Config” SafeSquid crashes.
Tested on safesquid version safesquid-2022.0610.1620.3 and safesquid-2022.0319.1457.3 which are both standard releases.
This crash can be replicated using any custom config.xml file which is incomplete.
We tested using a custom configuration file that only has application signature in it.
Attached is the custom configuration file to replicate similar crash if interested.
As per logs, we can validate that when trying to upload config.xml file safesquid looks for configuration settings for each section and gets errors because config.xml only has application signatures.
This config.xml file is foreign to safesquid, it becomes unresponsive and crashes.
We have attached the complete crash log for a detailed analysis of the problem.
