CVE-2025-4876

Estado: AnalizadaMedia (4.4)—

ConnectWise-Password-Encryption-Utility.exe in ConnectWise Risk Assessment allows an attacker to extract a hardcoded AES decryption key via reverse engineering. This key is embedded in plaintext within the binary and used in cryptographic operations without dynamic key management. Once obtained the key can be used to decrypt CSV input files used for authenticated network scanning.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
