Add vpatch-CVE-2025-34035 rule and test

[crowdsec-automation]

This rule detects exploitation attempts for CVE-2025-34035, an OS command injection vulnerability in EnGenius EnShare Cloud Service's usbinteract.cgi script. The attack is performed by sending a POST request to either /web/cgi-bin/usbinteract.cgi or /cgi-bin/usbinteract.cgi with the path parameter containing injected shell metacharacters (notably the pipe | character).

• The first rule clause matches any request URI containing /usbinteract.cgi, using lowercase and urldecode transforms to ensure case-insensitive and encoded input is handled.
• The second clause targets the path parameter in the POST body, again applying lowercase and urldecode transforms, and matches if it contains the pipe character (|), which is a strong indicator of command injection attempts.
• This approach minimizes false positives by focusing on the specific vulnerable endpoint and the parameter used for injection, and by looking for a shell metacharacter rather than a specific payload.
• All value: fields are lowercase, and transform includes lowercase and urldecode as required.
• The test nuclei template is adapted to only check for a 403 status code, as per guidelines.
