CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-42483 – ESP-NOW Replay Attacks Vulnerability
https://notcve.org/view.php?id=CVE-2024-42483
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. • https://github.com/espressif/esp-now/commit/4e30db50d541b2909d278ef0db05de1a3d7190ef https://github.com/espressif/esp-now/security/advisories/GHSA-wf6q-c2xr-77xj • CWE-349: Acceptance of Extraneous Untrusted Data With Trusted Data •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-42484 – ESP-NOW OOB Vulnerability In Group Type Message
https://notcve.org/view.php?id=CVE-2024-42484
ESP-NOW Component provides a connectionless Wi-Fi communication protocol. An Out-of-Bound (OOB) vulnerability was discovered in the implementation of the ESP-NOW group type message because there is no check for the addrs_num field of the group type message. This can result in memory corruption related attacks. Normally there are two fields in the group information that need to be checked, i.e., the addrs_num field and the addrs_list fileld. Since we only checked the addrs_list field, an attacker can send a group type message with an invalid addrs_num field, which will cause the message handled by the firmware to be much larger than the current buffer, thus causing a memory corruption issue that goes beyond the payload length. • https://github.com/espressif/esp-now/commit/b03a1b4593713fa4bf0038a87edca01f10114a7a https://github.com/espressif/esp-now/security/advisories/GHSA-q6f6-4qc5-vhx5 • CWE-125: Out-of-bounds Read •
