Last modified
CVE-2009-2070 is a vulnerability of currently unknown severity. Opera displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.. EPSS estimates a 0.84% chance of exploitation in the next 30 days.
