I am trying to gain access to a remote host running Ubuntu with Squirrel Mail 1.4.22. Ideally I need a reverse shell to traverse the machine to find a series of flags. I have discovered that POODLE is a potential attack but from what I have read, it is not very useful and cannot establish a reverse shell? I looked at some stuff online but the scripts I found all require me to have a login for the squirrel mail service. As this is a test environment, I do not have an account or access to create one. Any ideas would be greatly appreciated.

    Maybe you need to enumerate more in order to find the missing creds... In CTFs or pen-testing labs that's usually the case.

You may find that many of these XSS attacks (https://www.cvedetails.com/vulnerability-list/vendor_id-803/product_id-1366/year-2018/opxss-1/Squirrelmail-Squirrelmail.html) on Squirrelmail will allow you to perform a session hijack, bypassing the need to create an account, at which point a known vulnerability in 1.4.22 will allow remote code execution: https://www.cvedetails.com/cve/CVE-2017-7692/

If this is a test environment, the XSS attacks would still require a 'victim' to open the mailicious email. If that won't happen, you'll need another approach.
