Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • 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.

descriptionEaton Intelligent Power Manager (IPM) v1.67 and prior contain multiple vulnerabilities: - Improper Input Validation on file name during configuration file import functionality allows attackers to perform command injection or code execution via specially crafted file names while uploading the configuration file in the application (CVE-2020-6651). - Incorrect Privilege Assignment vulnerability allows non-admin users to upload the system configuration files by sending specially crafted requests. This can result in non-admin users manipulating the system configurations via uploading the configurations with incorrect parameters (CVE-2020-6652).
