| Summary |
An adversaries may add malicious content to a website through the open file share and then browse to that content with a web browser to cause the server to execute the content. The malicious content will typically run under the context and permissions of the web server process, often resulting in local system or administrative privileges depending on how the web server is configured. |
| Prerequisites |
|
| Solutions | Ensure proper permissions on directories that are accessible through a web server. Disallow remote access to the web root. Disable execution on directories within the web root. Ensure that permissions of the web server process are only what is required by not using built-in accounts and instead create specific accounts to limit unnecessary access or permissions overlap across multiple systems. |

Description

| CAPEC-17 |
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. |
