Vulnerability Details
CVEID: CVE-2015-7436
DESCRIPTION: Add/remove users to/from an external (namespace) group could
leave them with old permissions.
CVSS Base Score: 2.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107961 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2015-7435
DESCRIPTION: BackURL prefixed with white-space skips CAF validation.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107960 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/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 http://xforce.iss.net/xforce/xfdb/95328 for the
current score
CVSS Environmental Score*: Undefined
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 Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95327 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)
CVEID: CVE-2015-7450
DESCRIPTION: Apache Commons Collections could allow a remote attacker to
execute arbitrary code on the system, caused by the deserialization of data
with Java InvokerTransformer class. By sending specially crafted data, an
attacker could exploit this vulnerability to execute arbitrary Java code on
the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107918 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2015-4872
DESCRIPTION: An invalid (too short) RSA key might be accepted under certain
circumstances. The fix ensures that invalid RSA keys are rejected correctly.
This issue affects Java deployments which use SSL/TLS communication and/or the
java.security.cert.CertPath API.
CVSS Base Score: 5.0
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107361 for the current
