[AWS WAF] Can't hit the rule with managed rules included in custom rules

1

Hello,

I'm testing some rules on AWS WAF. As with the custom rules (such as URI), I can configure them successfully.

However, when I add another "label" rule inside this custom rule, it can never hit (count) although I can see the relevant logs.

Any advice? Thank you.

Can you perhaps share the rule syntax so that we can understand the logic better? Is it an "AND" or an "OR" condition?

  • I tried using "AND" or "OR" condition, or even just applied a single rule. Here are details of the rule: { "Name": "CustomCountRule-NoUserAgentHeader", "Priority": 0, "Statement": { "AndStatement": { "Statements": [ { "LabelMatchStatement": { "Scope": "LABEL", "Key": "awswaf:managed:aws:core-rule-set:NoUserAgent_Header" } }, { "NotStatement": { "Statement": { "ByteMatchStatement": { "SearchString": "<redacted>", "FieldToMatch": { "UriPath": {} }, "TextTransformations": [ { "Priority": 0, "Type": "NONE" } ], "PositionalConstraint": "CONTAINS" } } } } ] } }, "Action": { "Count": {} }, "VisibilityConfig": { "SampledRequestsEnabled": true, "CloudWatchMetricsEnabled": true, "MetricName": "CustomCountRule-NoUserAgentHeader" } }

Similar issue. Extremely basic IP match rule with default BLOCK results in the rule never being hit and all requests blocked with the IP that should be allowed through listed in the logs and in the "sample requests".
