Security Bulletin
Summary
Apache Tomcat which is shipped with WebSphere Application Server Community
Edition (WASCE) 3.0.0.4 is vulnerable to a remote attacker
Vulnerability Details
CVEID: CVE-2015-5345
DESCRIPTION: Apache Tomcat could allow a remote attacker to obtain sensitive
information, caused by an error when accessing a protected directory. By
redirecting to the URL, an attacker could exploit this vulnerability to
determine the presence of a directory.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110857 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2015-5346
DESCRIPTION: Apache Tomcat could allow a remote attacker to hijack a valid
user's session, caused by the failure to recycle the requestedSessionSSL
field when recycling the Request object to use for a new request. By
persuading a victim to visit a specially-crafted link and log into the
application, a remote attacker could exploit this vulnerability to hijack
another user's account and possibly launch further attacks on the system.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110854 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)
CVEID: CVE-2015-5351
DESCRIPTION: Apache Tomcat is vulnerable to cross-site request forgery,
caused by improper validation of user-supplied input by the index page. By
persuading an authenticated user to visit a malicious Web site, a remote
attacker could send a malformed HTTP request to perform unauthorized
actions. An attacker could exploit this vulnerability to perform cross-site
scripting attacks, Web cache poisoning, and other malicious activities.
CVSS Base Score: 8.8
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110859 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2016-0706
DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass
security restrictions, caused by the loading of the StatusManagerServlet
during the configuration of a security manager. An attacker could exploit
this vulnerability to obtain deployed applications and other sensitive
information.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110855 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-0714
DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass
security restrictions, caused by an error in multiple session persistence
mechanisms. By placing a malicious object into a session, an attacker
could exploit this vulnerability to bypass a security manager and possibly
execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110856 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2016-0763
DESCRIPTION: Apache Tomcat could allow a remote attacker
to bypass security restrictions, caused by an error in the
ResourceLinkFactory.setGlobalContext() method. By injecting malicious
content, an attacker could exploit this vulnerability to read and write
arbitrary data.
CVSS Base Score: 6.5
