CVE-2017-11717
MetInfo through 5.3.17 accepts the same CAPTCHA response for 120 seconds, which makes it easier for remote attackers to bypass intended challenge requirements by modifying the client-server data stream, as demonstrated by the login/findpass page.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
