Vulnerability Details
CVEID:
CVE-2014-9769
DESCRIPTION:
PCRE is vulnerable to a denial of service, caused by the failure to properly
use table jumps to optimize nested alternatives by pcre_jit_compile.c. A
remote attacker could exploit this vulnerability using a specially crafted
string to corrupt the stack and cause a segmentation fault.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111793
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID:
CVE-2015-2328
DESCRIPTION:
PCRE is vulnerable to a denial of service, caused by the improper handling of
patterns with certain internal recursive back references. A remote attacker
could exploit this vulnerability using a specially crafted regular expression
to cause a segmentation fault.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109276

CVEID:
CVE-2016-1283
DESCRIPTION:
PCRE is vulnerable to a heap-based buffer overflow, caused by the improper
handling of patterns by the pcre_compile2() function. By using a specially
crafted regular expression, a remote attacker could overflow a buffer and
execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 7.3

Summary
The IBM Tealeaf Customer Experience web portal is vulnerable to cross-site
scripting and redirect attacks and does not manage portal passwords as
documented.
Vulnerability Details
CVEID:
CVE-2016-5975
DESCRIPTION:
IBM Tealeaf Customer Experience is vulnerable to cross-site scripting. This
vulnerability allows users to embed arbitrary JavaScript code in the Web UI
thus altering the intended functionality potentially leading to credentials
disclosure within a trusted session.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116368

CVEID:
CVE-2016-5976
DESCRIPTION:
IBM Tealeaf Customer Experience could allow a privileged user to obtain
passwords to Tealeaf components.
CVSS Base Score: 4.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116369

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N)
CVEID:
CVE-2016-5977
DESCRIPTION:
IBM Tealeaf Customer Experience could allow a remote attacker to conduct
phishing attacks, using an open redirect attack. By persuading a victim to
visit a specially-crafted Web site, a remote attacker could exploit this
vulnerability to spoof the URL displayed to redirect a user to a malicious
Web site that would appear to be trusted. This could allow the attacker to
obtain highly sensitive information or conduct further attacks against the
victim.
