What is CVE-2013-3587?
CVE-2013-3587 is a medium-severity vulnerability in F5 Big-Ip Access Policy Manager, published on 21 Feb 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-200
