NimbostratusASM Learning Fine Tuning (illegal meta characters in value)
Hello Experts
My ASM policy is in transparent mode and configured as manually that is through wildcards for URL, Parameters and file types.
I am getting violations "illegal meta characters...
Hi,
- You must decide wich meta characters is allowed for the parameters.
- If you accept suggestion for wildcard parameters illegal meta characters would be accepted for all parameters but not for particular learned parameters.
- Allowed: Specifies that the character or meta character can occur in parameter values. Disallowed: Specifies that the character or meta character can not occur in parameter values.
- This settings came from /Security/Application Security/Parameters/Characters Sets

Nacreousyou can accept learning suggestion, if you don't see parameter name. I had the same issue and didn't find the way how to get parameter name wich had violation from logs.

NacreousYes, it will be accepted under wildcard parameter. If it's showing the parameter name you can accept learning suggestion and it will work only for that parameter.
