Azure Applicatoin Gateway WAF managed rule exclusion remove cli command not working as expected

• The command that you have used to delete the application gateway WAF managed rule exclusion set is incorrect. It should be as follows: –

  az network application-gateway waf-policy managed-rule exclusion rule-set remove -g MyResourceGroup --policy-name MyPolicy --match-variable RequestHeaderNames --match-operator StartsWith --selector Bing --type OWASP --version 3.2 --group-name MyRuleGroup

Similarly, when I tried the same in my environment, I was able to delete the same successfully as shown below with the command as given above by changing the required information in it: –

I have already created managed ruleset exclusion as seen above in the application gateway policy. Further, I executed the command as shown below and ensured that the managed ruleset exclusion gets deleted.

Command executed by me: –

 az network application-gateway waf-policy managed-rule exclusion rule-set remove -g <resource_group_name> --policy-name AGW1Policy --match-variable RequestHeaderNames --match-operator Equals --selector https://login.microsoftonline.com --type OWASP --version 3.0

Output: –

Thus, executing the command as said above does the job for me. Accordingly, ensure to execute the Azure CLI cmdlets accordingly.
