Vulnerability Details

CVEID:CVE-2011-1498
**DESCRIPTION:**Apache HttpComponents could allow a remote attacker to obtain sensitive information, caused by an unspecified error in HttpClient. An attacker could exploit this vulnerability to send the Proxy-Authorization header to the host and disclose the user’s password.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/66241 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/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-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.
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/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 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.
