Symptoms

lacking of detail in Evasion technique detected under support id when receiving massive illegal metacharacter violations.

Impact

The issue that was fixed is the amount of reporting per metacharacter. However, there are still reporting for each metacharacter, and since there are many meta character reporting, it feels the amount of memory and nothing left for reporting the sake of evasion techniques.

Conditions

Reporting of violation details for all illegal metachar in value/parameter name/header violations

Workaround

None.

Fix Information

Optimize reporting of illegal metachars on the same entity.

Behavior Change
