Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

This update also fixes the following bugs :

  - Previously, due to a too eager string size optimization
    on the IBM System z architecture, the 'wc' BusyBox
    command failed after processing standard input with the
    following error :

wc: : No such file or directory

This bug was fixed by disabling the string size optimization and the
'wc' command works properly on IBM System z architectures.

  - Prior to this update, the 'mknod' command was unable to
    create device nodes with a major or minor number larger
    than 255. Consequently, the kdump utility failed to
    handle such a device. The underlying source code has
    been modified, and it is now possible to use the 'mknod'
    command to create device nodes with a major or minor
    number larger than 255.

  - If a network installation from an NFS server was
    selected, the 'mount' command used the UDP protocol by
    default. If only TCP mounts were supported by the
    server, this led to a failure of the mount command. As a
    result, Anaconda could not continue with the
    installation. This bug is now fixed and NFS mount
    operations default to the TCP protocol."

"An updated rhev-hypervisor6 package that fixes multiple security
issues and one bug is now available.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The rhev-hypervisor6 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: a subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
extensions.

Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization
Hypervisor through the 3.2 Manager administration portal, the Host may
appear with the status of 'Install Failed'. If this happens, place the
host into maintenance mode, then activate it again to get the host
back to an 'Up' state.

A buffer overflow flaw was found in the way QEMU processed the SCSI
'REPORT LUNS' command when more than 256 LUNs were specified for a
single SCSI target. A privileged guest user could use this flaw to
corrupt QEMU process memory on the host, which could potentially
result in arbitrary code execution on the host with the privileges of
the QEMU process. (CVE-2013-4344)

Multiple flaws were found in the way Linux kernel handled HID (Human
Interface Device) reports. An attacker with physical access to the
system could use this flaw to crash the system or, potentially,
escalate their privileges on the system. (CVE-2013-2888,
CVE-2013-2889, CVE-2013-2892)

A flaw was found in the way the Python SSL module handled X.509
certificate fields that contain a NULL byte. An attacker could
potentially exploit this flaw to conduct man-in-the-middle attacks to
spoof SSL servers. Note that to exploit this issue, an attacker would
need to obtain a carefully crafted certificate signed by an authority
that the client trusts. (CVE-2013-4238)

The default OpenSSH configuration made it easy for remote attackers to
exhaust unauthorized connection slots and prevent other users from
being able to log in to a system. This flaw has been addressed by
enabling random early connection drops by setting MaxStartups to
10:30:100 by default. For more information, refer to the
sshd_config(5) man page. (CVE-2010-5107)

The CVE-2013-4344 issue was discovered by Asias He of Red Hat.

This updated package provides updated components that include fixes
for various security issues. These issues have no security impact on
Red Hat Enterprise Virtualization Hypervisor itself, however. The
security fixes included in this update address the following CVE
numbers :

CVE-2012-0786 and CVE-2012-0787 (augeas issues)

CVE-2013-1813 (busybox issue)

CVE-2013-0221, CVE-2013-0222, and CVE-2013-0223 (coreutils issues)

CVE-2012-4453 (dracut issue)

CVE-2013-4332, CVE-2013-0242, and CVE-2013-1914 (glibc issues)

CVE-2013-4592, CVE-2012-6542, CVE-2013-3231, CVE-2013-1929,
CVE-2012-6545, CVE-2013-1928, CVE-2013-2164, CVE-2013-2234, and
CVE-2013-2851 (kernel issues)

CVE-2013-4242 (libgcrypt issue)

CVE-2013-4419 (libguestfs issue)

CVE-2013-1775, CVE-2013-2776, and CVE-2013-2777 (sudo issues)

This update also fixes the following bug :

* A previous version of the rhev-hypervisor6 package did not contain
the latest vhostmd package, which provides a 'metrics communication
channel' between a host and its hosted virtual machines, allowing
limited introspection of host resource usage from within virtual
machines. This has been fixed, and rhev-hypervisor6 now includes the
latest vhostmd package. (BZ#1026703)

This update also contains the fixes from the following errata :

* ovirt-node: https://rhn.redhat.com/errata/RHBA-2013-1528.html

Users of the Red Hat Enterprise Virtualization Hypervisor are advised
to upgrade to this updated package, which corrects these issues."

    descriptionFrom Red Hat Security Advisory 2013:1732 : Updated busybox packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. BusyBox provides a single binary that includes versions of a large number of system commands, including a shell. This can be very useful for recovering from certain types of system failures, particularly those involving broken shared libraries. It was found that the mdev BusyBox utility could create certain directories within /dev with world-writable permissions.

"From Red Hat Security Advisory 2013:1732 :

Updated busybox packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

BusyBox provides a single binary that includes versions of a large
number of system commands, including a shell. This can be very useful
for recovering from certain types of system failures, particularly
those involving broken shared libraries.

It was found that the mdev BusyBox utility could create certain
directories within /dev with world-writable permissions. A local
unprivileged user could use this flaw to manipulate portions of the
/dev directory tree. (CVE-2013-1813)

This update also fixes the following bugs :

* Previously, due to a too eager string size optimization on the IBM
System z architecture, the 'wc' BusyBox command failed after
processing standard input with the following error :

wc: : No such file or directory

This bug was fixed by disabling the string size optimization and the
'wc' command works properly on IBM System z architectures. (BZ#820097)

* Prior to this update, the 'mknod' command was unable to create
device nodes with a major or minor number larger than 255.
Consequently, the kdump utility failed to handle such a device. The
underlying source code has been modified, and it is now possible to
use the 'mknod' command to create device nodes with a major or minor
number larger than 255. (BZ#859817)

* If a network installation from an NFS server was selected, the
'mount' command used the UDP protocol by default. If only TCP mounts
were supported by the server, this led to a failure of the mount
command. As a result, Anaconda could not continue with the
installation. This bug is now fixed and NFS mount operations default
to the TCP protocol. (BZ#855832)

All busybox users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues."
