CVE-2024-42483 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. ESP-NOW Component provides a connectionless Wi-Fi communication protocol. An replay attacks vulnerability was discovered in the implementation of the ESP-NOW because the caches is not differentiated by message types, it is a single, shared resource for all kinds of messages, whether they are broadcast or unicast, and regardless of whether they are ciphertext or plaintext. EPSS estimates a 0.30% chance of exploitation in the next 30 days.

Description

ESP-NOW Component provides a connectionless Wi-Fi communication protocol. An replay attacks vulnerability was discovered in the implementation of the ESP-NOW because the caches is not differentiated by message types, it is a single, shared resource for all kinds of messages, whether they are broadcast or unicast, and regardless of whether they are ciphertext or plaintext. This can result an attacker to clear the cache of its legitimate entries, there by creating an opportunity to re-inject previously captured packets. This vulnerability is fixed in 2.5.2.
