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.

| description | According to its version number, the CommonSpot install hosted on the remote web server is affected by multiple vulnerabilities : - An access restriction bypass via a direct request. (CVE-2014-2859) - Multiple cross-site scripting (XSS) vulnerabilities. (CVE-2014-2860, CVE-2014-2861) - Improper authorization checks in unspecified requests can allow a remote, unauthenticated attacker to perform unauthorized actions. (CVE-2014-2862) - Multiple path traversal vulnerabilities allow remote, unauthenticated attackers to request full pathnames in parameters. (CVE-2014-2863) - Multiple directory traversal vulnerabilities. (CVE-2014-2864) - The application fails to restrict the use of a NULL byte, which can be used to bypass access restrictions. (CVE-2014-2865) - The application uses client JavaScript code for access restrictions, which can be bypassed with attacker- controlled JavaScript. (CVE-2014-2866) - Unrestricted file uploads could allow for dangerous file types to be added to the server. (CVE-2014-2867) - Multiple pages allow a remote attacker to override ColdFusion variables via HTTP GET requests. (CVE-2014-2868) - Multiple pages allow for information disclosure. (CVE-2014-2869) - The application stores credentials in plaintext in the underlying application database by default. (CVE-2014-2870) - The application transmits credentials in cleartext via HTTP. (CVE-2014-2871) - Multiple directory listings allow for potential access to sensitive information. (CVE-2014-2872) - The application allows unauthenticated access to log files allowing for information disclosure. (CVE-2014-2873) - The application allows remote, unauthenticated attackers to execute arbitrary commands with arbitrary parameters. (CVE-2014-2874) Note that Nessus has not tested for these issues but has instead relied only on the application |
