vulnerable to SWEET32 Birthday attack (CVE-2016-2183)
23 February 2017
AusCERT Security Bulletin Summary
Product: IBM WebSphere MQ
Operating System: Linux variants
Impact/Access: Access Privileged Data -- Remote/Unauthenticated
CVE Names: CVE-2016-2183
- --------------------------BEGIN INCLUDED TEXT--------------------
Security Bulletin: IBM MQ and IBM MQ Appliance are vulnerable to SWEET32 Birthday attack (CVE-2016-2183)
More support for: IBM MQ
Software version: 7.0.1, 7.1, 7.5, 8.0, 9.0, 9.0.1
Operating system(s): Platform Independent
Software edition: All Editions
Reference #: 1995099
Modified date: 22 February 2017
A security vulnerability affects IBM MQ and IBM MQ Appliance, that could allow an attacker to obtain sensitive information when using a channel CipherSpec that uses the Triple-DES algorithm. The affected CipherSpecs are:
- - TRIPLE_DES_SHA_US
- - FIPS_WITH_3DES_EDE_CBC_SHA
- - ECDHE_ECDSA_3DES_EDE_CBC_SHA256
- - ECDHE_RSA_3DES_EDE_CBC_SHA256
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.
