Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect Rational RequisitePro

Summary

There are multiple vulnerabilities in IBM® SDK Java™ Technology Edition that is shipped with IBM WebSphere Application Server, which is needed for the RequisiteWeb component of Rational RequisitePro. These issues were disclosed as part of the IBM Java SDK updates in April 2015.

This bulletin also addresses FREAK: Factoring Attack on RSA-EXPORT keys" SSL/TLS vulnerability and RC4 Bar Mitzvah Attack for SSL/TLS vulnerability.

Vulnerability Details

CVEID: CVE-2015-0488**
DESCRIPTION:** An unspecified vulnerability related to the JSSE component could allow a remote attacker to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See _<https://exchange.xforce.ibmcloud.com/vulnerabilities/102336&gt;_ for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0478**
DESCRIPTION:** An unspecified vulnerability related to the JCE component could allow a remote attacker to obtain sensitive information.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/102339&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

CVEID: CVE-2015-0204**
DESCRIPTION:** A vulnerability in the OpenSSL ssl3_get_key_exchange function could allow a remote attacker to downgrade the security of certain TLS connections. An OpenSSL client accepts the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See _<https://exchange.xforce.ibmcloud.com/vulnerabilities/99707&gt;_ for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)**

CVEID:** CVE-2015-2808**
DESCRIPTION:** The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as “Bar Mitzvah Attack”.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N) **

CVEID:** CVE-2015-1916**
DESCRIPTION:** Server applications which use the IBM Java Secure Socket Extension provider to accept SSL/TLS connections are vulnerable to a denial of service attack due to an unspecified vulnerability.
CVSS Base Score: 5
CVSS Temporal Score: See _<https://exchange.xforce.ibmcloud.com/vulnerabilities/101995&gt;_ for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) **

CVEID:** CVE-2015-0138**
DESCRIPTION:** A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/100691&gt; for the current score
CVSS Environmental Score*: Undefined
