Security Bulletin: IBM B2B Advanced Communications is vulnerable to multiple issues due to Apache HttpClient

Summary

IBM B2B Advanced Communications has addressed vulnerabilities in Apache HttpClient shipped with product.

Vulnerability Details

CVEID:CVE-2020-13956
**DESCRIPTION:**Apache HttpClient could allow a remote attacker to bypass security restrictions, caused by the improper handling of malformed authority component in request URIs. By passing request URIs to the library as java.net.URI object, an attacker could exploit this vulnerability to pick the wrong target host for request execution.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189572 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2014-3577
**DESCRIPTION:**Apache HttpComponents could allow a remote attacker to conduct spoofing attacks, caused by the failure to verify that the server hostname matches a domain name in the Subject’s Common Name (CN) or SubjectAltName field of certificates. By persuading a victim to visit a Web site containing a specially-crafted certificate, an attacker could exploit this vulnerability using man-in-the-middle techniques to spoof an SSL server.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/95327 for the current score.
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID:CVE-2012-5783
**DESCRIPTION:**Apache Commons HttpClient, as used in Amazon Flexible Payments Service (FPS) merchant Java SDK and other products, could allow a remote attacker to conduct spoofing attacks, caused by the failure to verify that the server hostname matches a domain name in the subject’s Common Name (CN) field of the X.509 certificate. By persuading a victim to visit a Web site containing a specially-crafted certificate, an attacker could exploit this vulnerability using man-in-the-middle techniques to spoof an SSL server.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/79984 for the current score.
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID:CVE-2015-5262
**DESCRIPTION:**Apache Commons is vulnerable to a denial of service, caused by the failure to apply a configured connection during the initial handshake of an HTTPS connection by the HttpClient component. An attacker could exploit this vulnerability to accumulate multiple connections and exhaust all available resources.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/106932 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2012-6153
**DESCRIPTION:**Apache HttpComponents could allow a remote attacker to conduct spoofing attacks, caused by an incomplete fix related to the failure to verify that the server hostname matches a domain name in the Subject’s Common Name (CN) or SubjectAltName field of certificates. By persuading a victim to visit a Web site containing a specially-crafted certificate, an attacker could exploit this vulnerability using man-in-the-middle techniques to spoof an SSL server.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/95328 for the current score.
