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.

"From Red Hat Security Advisory 2013:0522 :

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

The Red Hat Security Response Team has rated this update as having
moderate 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.

The GNU Debugger (GDB) allows debugging of programs written in C, C++,
Java, and other languages by executing them in a controlled fashion
and then printing out their data.

GDB tried to auto-load certain files (such as GDB scripts, Python
scripts, and a thread debugging library) from the current working
directory when debugging programs. This could result in the execution
of arbitrary code with the user's privileges when GDB was run in a
directory that has untrusted content. (CVE-2011-4355)

With this update, GDB no longer auto-loads files from the current
directory and only trusts certain system directories by default. The
list of trusted directories can be viewed and modified using the 'show
auto-load safe-path' and 'set auto-load safe-path' GDB commands. Refer
to the GDB manual, linked to in the References, for further
information.

This update also fixes the following bugs :

* When a struct member was at an offset greater than 256 MB, the
resulting bit position within the struct overflowed and caused an
invalid memory access by GDB. With this update, the code has been
modified to ensure that GDB can access such positions. (BZ#795424)

* When a thread list of the core file became corrupted, GDB did not
print this list but displayed the 'Cannot find new threads: generic
error' error message instead. With this update, GDB has been modified
and it now prints the thread list of the core file as expected.
(BZ#811648)

* GDB did not properly handle debugging of multiple binaries with the
same build ID. This update modifies GDB to use symbolic links created
for particular binaries so that debugging of binaries that share a
build ID now proceeds as expected. Debugging of live programs and core
files is now more user-friendly. (BZ#836966)

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

    descriptionAn updated rhev-hypervisor6 package that fixes three security issues, various bugs, and adds an enhancement 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. A flaw was found in the way the vhost kernel module handled descriptors that spanned multiple regions. A privileged guest user could use this flaw to crash the host or, potentially, escalate their privileges on the host. (CVE-2013-0311) It was found that the default SCSI command filter does not accommodate commands that overlap across device classes. A privileged guest user could potentially use this flaw to write arbitrary data to a LUN that is passed-through as read-only. (CVE-2012-4542) It was discovered that dnsmasq, when used in combination with certain libvirtd configurations, could incorrectly process network packets from network interfaces that were intended to be prohibited. A remote, unauthenticated attacker could exploit this flaw to cause a denial of service via DNS amplification attacks. (CVE-2012-3411) The CVE-2012-4542 issue was discovered by Paolo Bonzini of Red Hat. This updated package provides updated components that include fixes for several security issues. These issues had no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2012-3955 (dhcp issue) CVE-2011-4355 (gdb issue) CVE-2012-4508, CVE-2013-0190, CVE-2013-0309, and CVE-2013-0310 (kernel issues) CVE-2012-5536 (openssh issue) CVE-2011-3148 and CVE-2011-3149 (pam issues) CVE-2013-0157 (util-linux-ng issue) This updated Red Hat Enterprise Virtualization Hypervisor package also fixes the following bugs : * Previously, the Administration Portal would always display the option to upgrade the Red Hat Enterprise Virtualization Hypervisor ISO regardless of whether or not the selected host was up-to-date. Now, the VDSM version compatibility is considered and the upgrade message only displays if there is an upgrade relevant to the host available. (BZ#853092) * An out of date version of libvirt was included in the Red Hat Enterprise Virtualization Hypervisor 6.4 package. As a result, virtual machines with supported CPU models were not being properly parsed by libvirt and failed to start. A more recent version of libvirt has been included in this updated hypervisor package. Virtual machines now start normally. (BZ#895078) As well, this update adds the following enhancement : * Hypervisor packages now take advantage of the installonlypkg function provided by yum. This allows for multiple versions of the hypervisor package to be installed on a system concurrently without making changes to the yum configuration as was previously required. (BZ#863579) This update includes the ovirt-node build from RHBA-2013:0556 : https://rhn.redhat.com/errata/RHBA-2013-0556.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues and adds this enhancement.
