sol14634: SSL / TLS BREACH vulnerability - CVE-2013-3587 

Security Advisory

Original Publication Date: 08/22/2013


The BREACH vulnerability allows attackers to discover secrets wrapped in HTTP
compression inside of SSL. By injecting plaintext into an HTTPS request, an 
attacker can learn information about the corresponding HTTPS response by 
measuring its size. This action relies on the attacker's ability to observe 
the size of the ciphertext received by the browser while triggering a number 
of strategically crafted requests to a target site.


By observing the length of compressed HTTPS responses, an attacker may be able
to obtain plaintext secrets from the ciphertext of an HTTPS stream.


F5 Product Development has assigned ID 427375 (BIG-IP and Enterprise Manager)
ID 428152 (FirePass), and ID 428241 (ARX) to this vulnerability.
