5) Information disclosure

EUVDB-ID: #VU370

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2016-2183

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: No

Description

The vulnerability allows a remote attacker to decrypt transmitted data.

The vulnerability exists due to remote user's ability to control the network and capture long duration 3DES CBC mode encrypted session during which he can see a part of the text. In case of repeated sending the attacker can read the part and reconstruct the whole text.

Successful exploitation of this vulnerability may allow a remote attacker to decode transmitted data. This vulnerability is known as SWEET32.
