Hi @Zxxxx, thank you for opening the request. After reviewing this vulnerability ref, there are a few concerns about how Tsunami scanner can verify the vulnerability:

  1. A zip file upload is needed, and it's uncertain if there's a way to delete the file afterwards. Ideally Tsunami doesn't leave any permanent state changing results on the server.
  2. The exploit used in the ref uploads a jsp file via zip to Zimbra's public directory, and makes a get request to that file to trigger it. This would require us to guess the Zimbra server directory location, and the detector could miss non-standard Zimbra installations.

Please let me know if you have a more reliable way in mind to detect this vulnerability to address the concerns above.
