Vulnerabilities > CVE-2015-9267 - Improper Privilege Management vulnerability in multiple products
Nullsoft Scriptable Install System (NSIS) before 2.49 uses temporary folder locations that allow unprivileged local users to overwrite files. This allows a local attack in which either a plugin or the uninstaller can be replaced by a Trojan horse program.
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.

|description||Among others, Andre Heinicke from gpg4win.org found several issues of nsis, a tool for creating quick and user friendly installers for Microsoft Windows operating systems. The issues are fixed by ... ... using SetDefaultDllDirectories() to restrict implicitly loaded and dynamically loaded modules to trusted directories ... creating temporary directories in a way that only elevated users can write into it ... not implicitly linking against Version.dll but using wrapper functions For Debian 8|
