RCE Covenant

Description

Covenant 0.1.3 - 0.5 contains a remote code execution vulnerability that allows attackers to craft malicious JWT tokens with administrative privileges. Attackers can generate forged tokens with admin roles and upload custom DLL payloads to execute arbitrary commands on the target system.

Analysis

Covenant C2 framework (0.1.3-0.5) allows forging JWT tokens with admin roles due to hardcoded credentials. Attackers can upload and execute DLL payloads for RCE. PoC available.

Technical Context

The JWT signing key is hardcoded (CWE-798), allowing attackers to forge tokens with admin roles. With admin access, they can upload custom DLL payloads that execute arbitrary code on the Covenant server.

Affected Products
