Sterling Connect:Direct for Microsoft Windows 4.6.0 Fix Packs

APAR status

• Closed as program error.

Error description

• The Bar Mitzvah Attack exploits a previously known
  vulnerability in the RC4 component of the SSL/TLS communication
  protocols. This exploit allows the attacker to partially
  decrypt information sent between two computer systems across a
  network.
  IBM Sterling Connect:Direct for Microsoft Windows can use
  SSL/TLS communication and therefore is vulnerable.
  

Local fix

• STRRTC - 462325
  VF / VF
  Circumvention: None
  

Problem summary

• Users Affected:
  Sterling Connect:Direct for Windows 4.5.00
  Sterling Connect:Direct for Windows 4.5.01
  Sterling Connect:Direct for Windows 4.6.0
  Sterling Connect:Direct for Windows 4.7.0
  
  Problem Description:
  CBC ciphers are vulnerable to CVE-2011-3389 (BEAST Attack).
  Previous recommendation to mitigate CVE-2011-3389 was to not
  use CBC ciphers. RC4 ciphers are vulnerable to CVE-2015-2808
  (Bar Mitzvah Attack). Current recommendation to mitigate
  CVE-2015-2808 is to discontinue use of RC4 ciphers. However,
  the remaining available ciphers are generally CBC ciphers.
  
  Platforms Affected:
  Windows
  

Problem conclusion

• Resolution Summary:
  Fixed code to mitigate CVE-2011-3389 (BEAST Attack).
  Recommendation:
  Sterling Connect:Direct for Microsoft Windows by default
  disables the RC4 stream cipher. If you enabled the RC4 stream
  cipher you are exposed to the RC4  Bar Mitzvah  Attack
  for SSL/TLS. IBM recommends that you review your entire
  environment to identify other areas where you have enabled the
  RC4 stream cipher and take appropriate mitigation and
  remediation actions.
