CVE-2021-21433 describes a Remote Code Execution (RCE) vulnerability within Discord-Recon Server, a bot designed for reconnaissance tasks. This vulnerability allows unauthorized remote users to execute commands on the server, potentially leading to complete system compromise. The vulnerability affects versions of Discord-Recon Server up to and including 0.0.1, and a fix is available in version 0.0.2.
The impact of this RCE vulnerability is severe. An attacker exploiting this flaw gains the ability to execute arbitrary commands on the server hosting the Discord-Recon bot. This could lead to data exfiltration, malware installation, system takeover, and lateral movement within the network. Depending on the server's configuration and access privileges, the attacker could potentially compromise other systems connected to the same network. The bot's reconnaissance capabilities could also be abused to gather sensitive information about the target environment.
This vulnerability was publicly disclosed on April 9, 2021. While no active exploitation campaigns have been definitively linked to CVE-2021-21433, the ease of exploitation and the potential impact make it a high-priority target. No public proof-of-concept (PoC) code has been widely distributed, but the vulnerability's nature suggests that such code could be developed relatively easily. It is not listed on the CISA KEV catalog as of this writing.
Organizations and individuals utilizing Discord-Recon Server for reconnaissance purposes are at risk, particularly those running older, unpatched versions (≤ 0.0.1). Environments where the Discord-Recon server has elevated privileges or network access are at higher risk of broader compromise.

The primary mitigation for CVE-2021-21433 is to immediately upgrade Discord-Recon Server to version 0.0.2 or later. If upgrading is not immediately feasible due to compatibility issues or downtime concerns, consider isolating the affected server from the network to prevent potential exploitation. While a direct WAF rule is unlikely to be effective, monitoring server logs for suspicious command execution attempts is recommended. After upgrading, verify the fix by attempting to execute a command through the bot interface and confirming that it is rejected.
Actualice la versión de Discord-Recon a la 0.0.2 o superior. Esta versión corrige la vulnerabilidad de ejecución remota de código debido a una validación de entrada incorrecta. Puede actualizar el paquete utilizando pip: `pip install discord-recon==0.0.2`.
