CVE-2024-5764 is a vulnerability in Sonatype Nexus Repository (versions 3.0.0 through 3.72.0) where the code responsible for encrypting secrets in the configuration database (such as SMTP/HTTP proxy credentials and user tokens) uses a static, hard-coded encryption passphrase. Although administrators could set a custom passphrase, this could only be done at first boot and could not be changed later, leaving secrets at risk if the static passphrase is known or leaked.

This repository provides a Python proof-of-concept exploit for CVE-2024-5764, a vulnerability in Sonatype Nexus Repository Manager 3 where a static, hardcoded encryption passphrase is used by default. The main script, 'cve-2024-5764.py', implements the decryption logic used by the Java PasswordCipher class, allowing an attacker to decrypt data (such as credentials) that was encrypted with the static passphrase. The script accepts a base64-encoded encrypted payload and an optional passphrase (defaulting to the known static value), and outputs the decrypted data. The repository includes a README with usage instructions, a requirements.txt specifying 'pycryptodome', and standard license and funding files. No network endpoints or external services are targeted; the exploit operates on provided encrypted data, making it a local decryption tool rather than a remote exploit.
