SOL30971148: Apache Tomcat 6.x vulnerabilities CVE-2015-5174, CVE-2015-5345,
CVE-2016-0706, and CVE-2016-0714
Security Advisory
Original Publication Date: 03/22/2016
Vulnerability Description
CVE-2015-5174
Directory traversal vulnerability in RequestUtil.java in Apache Tomcat 6.x
before 6.0.45, 7.x before 7.0.65, and 8.x before 8.0.27 allows remote
authenticated users to bypass intended SecurityManager restrictions and list a
parent directory via a /.. (slash dot dot) in a pathname used by a web
application in a getResource, getResourceAsStream, or getResourcePaths call,
as demonstrated by the $CATALINA_BASE/webapps directory.
CVE-2015-5345
The Mapper component in Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.67,
8.x before 8.0.30, and 9.x before 9.0.0.M2 processes redirects before
considering security constraints and Filters, which allows remote attackers to
determine the existence of a directory via a URL that lacks a trailing /
(slash) character.
CVE-2016-0706
Apache Tomcat 6.x before 6.0.45, 7.x before 7.0.68, 8.x before 8.0.31, and 9.x
before 9.0.0.M2 does not place
org.apache.catalina.manager.StatusManagerServlet on the
org/apache/catalina/core/RestrictedServlets.properties list, which allows
remote authenticated users to bypass intended SecurityManager restrictions and
read arbitrary HTTP requests, and consequently discover session ID values, via
a crafted web application.
CVE-2016-0714
The session-persistence implementation in Apache Tomcat 6.x before 6.0.45, 7.x
before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M2 mishandles session
attributes, which allows remote authenticated users to bypass intended
SecurityManager restrictions and execute arbitrary code in a privileged
context via a web application that places a crafted object in a session.
Impact
CVE-2015-5174
A remote authenticated user may bypass the security manager to obtain a
directory listing for the directory where the web application was deployed.
BIG-IP/Enterprise Manager
The level of access required to create and deploy a malicious web application
implies a user with a significant trust level (for example: root). BIG-IP and
Enterprise Manager systems do not support customized web applications within
the Tomcat configuration.
Traffix SDC
Exploitation of this vulnerability may occur if an attacker has access to the
local network of the system; the Tomcat service is accessible only from the
internal network.
CVE-2015-5345
A remote attacker may be able to determine the existence of restricted
directories by exploiting this vulnerability.
BIG-IP/Enterprise Manager
The Tomcat service is not directly exposed to the network, as it only listens
on a localhost socket with connections brokered through the Apache front-end
web service.
Traffix SDC
Exploitation of this vulnerability may occur if an attacker has access to the
local network of the system; the Tomcat service is accessible only from the
internal network.
CVE-2016-0706
When this vulnerability is exploited via crafted web application, a remote
authenticated user may bypass the intended security manager restrictions, read
arbitrary HTTP requests, and discover session ID values.
BIG-IP/Enterprise Manager
BIG-IP and Enterprise Manager systems do not use the affected feature. The
vulnerable software is present; however, the software is not used in a way
that exposes this vulnerability.
Traffix SDC
Exploitation of this vulnerability may occur if an attacker has access to the
local network of the system; the Tomcat service is accessible only from the
internal network.
CVE-2016-0714
A remote authenticated user may bypass the intended security manager
restrictions and execute arbitrary code in a privileged context by exploiting
this vulnerability via a web application that places a crafted object in a
session.
BIG-IP/Enterprise Manager
BIG-IP and Enterprise Manager systems do not use the affected feature. The
vulnerable software is present; however, the software is not used in a way
that exposes this vulnerability.
Traffix SDC
Exploitation of this vulnerability may occur if an attacker has access to the
local network of the system; the Tomcat service is accessible only from the
internal network.
Security Issue Status
F5 Product Development has assigned IDs 576878, 576881, 576883, and 576884
