Add vpatch-CVE-2022-0434 rule and test

[crowdsec-automation]

This rule targets the SQL injection vulnerability in the WordPress Page Views Count plugin (CVE-2022-0434). The attack is performed via the post_ids parameter in a REST endpoint, as seen in the nuclei template.

• The first rule condition matches requests to the vulnerable REST route by checking if the URI contains /?rest_route=/pvc/v1/increase/, using both lowercase and urldecode transforms to ensure normalization and case insensitivity.
• The second rule condition inspects the post_ids argument for the SQL injection pattern ) union select , which is a clear indicator of an attempted SQL injection. Again, lowercase and urldecode are applied for normalization.
• The use of contains ensures the rule is robust against variations in the attack string.
• The labels section includes the correct CVE, ATT&CK, and CWE references, and the product/vuln class label is formatted as required.

Validation checklist:

• All value: fields are lowercase.
• All relevant transforms include lowercase and urldecode.
• No match.value contains capital letters.
• The rule uses contains instead of regex where applicable.
