CVE-2024-23688
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk39th percentile - higher than 39% of all known CVEs
Summary
The vulnerability in Consensys Discovery versions prior to 0.4.5 uses the same AES/GCM nonce for the entire session, while it should be unique for every message. The node's private key is not compromised, only the session key generated for specific peer communication is exposed.
Risk Assessment
The risk is that an attacker could decrypt all communication within a session, potentially leading to the leakage of sensitive data exchanged between nodes.
Recommendation
Immediately update the Consensys Discovery library to version 0.4.5 or later, which generates a unique nonce for each message.
