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.

"An update is now available for Red Hat Gluster Storage 3.2 on Red Hat
Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Red Hat Gluster Storage is a software only scale-out storage solution
that provides flexible and affordable unstructured data storage. It
unifies data storage and infrastructure, increases performance, and
improves availability and manageability to meet enterprise-level
storage challenges.

The following packages have been upgraded to a later upstream version:
glusterfs (3.8.4), redhat-storage-server (3.2.0.3). (BZ#1362373)

Security Fix(es) :

* It was found that glusterfs-server RPM package would write file with
predictable name into world readable /tmp directory. A local attacker
could potentially use this flaw to escalate their privileges to root
by modifying the shell script during the installation of the
glusterfs-server package. (CVE-2015-1795)

This issue was discovered by Florian Weimer of Red Hat Product
Security.

Bug Fix(es) :

* Bricks remain stopped if server quorum is no longer met, or if
server quorum is disabled, to ensure that bricks in maintenance are
not started incorrectly. (BZ#1340995)

* The metadata cache translator has been updated to improve Red Hat
Gluster Storage performance when reading small files. (BZ#1427783)

* The 'gluster volume add-brick' command is no longer allowed when the
replica count has increased and any replica bricks are unavailable.
(BZ# 1404989)

* Split-brain resolution commands work regardless of whether
client-side heal or the self-heal daemon are enabled. (BZ#1403840)

Enhancement(s) :

* Red Hat Gluster Storage now provides Transport Layer Security
support for Samba and NFS-Ganesha. (BZ#1340608, BZ#1371475)

* A new reset-sync-time option enables resetting the sync time
attribute to zero when required. (BZ#1205162)

* Tiering demotions are now triggered at most 5 seconds after a
hi-watermark breach event. Administrators can use the
cluster.tier-query-limit volume parameter to specify the number of
records extracted from the heat database during demotion. (BZ#1361759)

* The /var/log/glusterfs/etc-glusterfs-glusterd.vol.log file is now
named / var/log/glusterfs/glusterd.log. (BZ#1306120)

* The 'gluster volume attach-tier/detach-tier' commands are considered
deprecated in favor of the new commands, 'gluster volume tier VOLNAME
attach/detach'. (BZ#1388464)

* The HA_VOL_SERVER parameter in the ganesha-ha.conf file is no longer
used by Red Hat Gluster Storage. (BZ#1348954)

* The volfile server role can now be passed to another server when a
server is unavailable. (BZ#1351949)

* Ports can now be reused when they stop being used by another
service. (BZ# 1263090)

* The thread pool limit for the rebalance process is now dynamic, and
is determined based on the number of available cores. (BZ#1352805)

* Brick verification at reboot now uses UUID instead of brick path.
(BZ# 1336267)

* LOGIN_NAME_MAX is now used as the maximum length for the slave user
instead of __POSIX_LOGIN_NAME_MAX, allowing for up to 256 characters
including the NULL byte. (BZ#1400365)

* The client identifier is now included in the log message to make it
easier to determine which client failed to connect. (BZ#1333885)"
