Description
Hi All,
Token generator is not working below is how I initiated the extension. There were two JSESSION IDs displayed I tried with both.
Here is the flow of authentication.
- Username and password is sent in POST request to the server.
- Servers sends a redirects to the index page ("302" request), sets the cookie using "Set-Cookie:"
I notice that ZAP doesn't find the session token,
I get the below error message from the logs
2015-12-10 14:17:06,301 [Thread-328] ERROR ZAP$UncaughtExceptionLogger - Exception in thread "Thread-328" java.lang.ArithmeticException: / by zero at org.zaproxy.zap.extension.tokengen.CharacterFrequencyMap.checkCharacterUniformity(CharacterFrequencyMap.java:134) at org.zaproxy.zap.extension.tokengen.TokenAnalyserThread.run(TokenAnalyserThread.java:97)

Research direction
Start with CharacterFrequencyMap.checkCharacterUniformity and TokenAnalyserThread.run, where the reported ArithmeticException occurs. Reproduce the token-generator flow using the JSESSION IDs from the authentication response, then verify that token analysis completes without the divide-by-zero failure.
