Improper Control of Generation of Code ('Code Injection')

CVE-2021-29461

Severity High
Score 8.1/10

Summary

Discord Recon Server is a bot that allows one to do one's reconnaissance process from one's Discord. A vulnerability in Discord Recon Server prior to 0.0.3 could be exploited to read internal files from the system and write files into the system resulting in remote code execution. This issue has been fixed in version 0.0.3. As a workaround, one may copy the code from `assets/CommandInjection.py` in the Discord Recon Server code repository and overwrite vulnerable code from one's own Discord Recon Server implementation with code that contains the patch.

CWE-94 - Code Injection

Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
