CVE-2012-4930

SPDY: SSL/TLS CRIME attack

Published Sep 15, 2012 CVSS 2.0 · 2.6 Low EPSS 2.1% KEV · Not listed
Description
The SPDY protocol 3 and earlier, as used in Mozilla Firefox, Google Chrome, and other products, can perform TLS encryption of compressed data without properly obfuscating the length of the unencrypted data, which allows man-in-the-middle attackers to obtain plaintext HTTP headers by observing length differences during a series of guesses in which a string in an HTTP request potentially matches an unknown string in an HTTP header, aka a "CRIME" attack.
