CVE-2013-3587

MEDIUMCVSS 5.9/10EPSS 6.05%

Last modified

CVE-2013-3587 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. The HTTPS protocol, as used in unspecified web applications, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which makes it easier for man-in-the-middle attackers to obtain plaintext secret values by observing length differences during a series of guesses in which a string in an HTTP request URL potentially matches an unknown string in an HTTP response body, aka a "BREACH" attack, a different issue than CVE-2012-4929.. EPSS estimates a 6.05% chance of exploitation in the next 30 days.
