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.

    descriptionpolkit was updated to the 0.113 release, fixing security issues and bugs. Security issues fixed : - Fixes CVE-2015-4625, a local privilege escalation due to predictable authentication session cookie values. Thanks to Tavis Ormandy, Google Project Zero for reporting this issue. For the future, authentication agents are encouraged to use PolkitAgentSession instead of using the D-Bus agent response API directly. (bsc#935119) - Fixes CVE-2015-3256, various memory corruption vulnerabilities in use of the JavaScript interpreter, possibly leading to local privilege escalation. (bsc#943816) - Fixes CVE-2015-3255, a memory corruption vulnerability in handling duplicate action IDs, possibly leading to local privilege escalation. Thanks to Laurent Bigonville for reporting this issue. (bsc#939246) - Fixes CVE-2015-3218, which allowed any local user to crash polkitd. Thanks to Tavis Ormandy, Google Project Zero, for reporting this issue. (bsc#933922) Other issues fixed : - On systemd-213 and later, the

    descriptionAccording to the versions of the polkit package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - The polkit_backend_action_pool_init function in polkitbackend/polkitbackendactionpool.c in PolicyKit (aka polkit) before 0.113 might allow local users to gain privileges via duplicate action IDs in action descriptions.(CVE-2015-3255) - The authentication_agent_new function in polkitbackend/polkitbackendinteractiveauthority.c in PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (NULL pointer dereference and polkitd daemon crash) by calling RegisterAuthenticationAgent with an invalid object path.(CVE-2015-3218) - A flaw was found in PolicyKit (aka polkit) 0.115 that allows a user with a uid greater than INT_MAX to successfully execute any systemctl command.(CVE-2018-19788) - A flaw was found in polkit before version 0.116. The implementation of the polkit_backend_interactive_authority_check_authorizatio n function in polkitd allows to test for authentication and trigger authentication of unrelated processes owned by other users. This may result in a local DoS and information disclosure.(CVE-2018-1116) - Integer overflow in the authentication_agent_new_cookie function in PolicyKit (aka polkit) before 0.113 allows local users to gain privileges by creating a large number of connections, which triggers the issuance of a duplicate cookie value.(CVE-2015-4625) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
