Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU90
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2015-2808
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information communicated by target system.
The vulnerability exists due to access control error. A remote unauthenticated attacker can obtain RC4 encrypted data and conduct a brute-force key guessing attack by monitoring TLS network traffic.
Successful exploitation of this vulnerability may result in disclosure of system information.
Install update from vendor's website.
Vulnerable software versionsWebSphere Message Broker Toolkit: All versions
IBM Integration Bus: All versions
Integration Toolkit: before 9.0 Fix Pack 3

2) Input validation error
EUVDB-ID: #VU33689
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2011-3389
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.
