Summary

The file-management system in Movable Type before 4.38, 5.0x before 5.07, and 5.1x before 5.13 allows remote authenticated users to execute arbitrary commands by leveraging the file-upload feature, related to an "OS Command Injection" issue.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • 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.
  • Manipulating User-Controlled Variables
    This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An attacker can override environment variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the attacker can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

system :

Under certain circumstances, a user who has 'Create Entries' or'Manage
Blog' permissions may be able to read known files on the local file
system.

The file management system contains shell command injection
vulnerabilities, the most serious of which may lead to arbitrary OS
command execution by a user who has a permission to sign-in to the
admin script and also has a permission to upload files.

Session hijack and cross-site request forgery vulnerabilities exist in
the commenting and the community script. A remote attacker could
hijack the user session or could execute arbitrary script code on
victim's browser under the certain circumstances.

Templates which do not escape variable properly and mt-wizard.cgi
contain cross-site scripting vulnerabilities."
