CVSS: 6.6EPSS: 0%CPEs: 4EXPL: 0CVE-2024-53845 – AES/CBC Constant IV Vulnerability in ESPTouch v2
https://notcve.org/view.php?id=CVE-2024-53845
ESPTouch is a connection protocol for internet of things devices. In the ESPTouchV2 protocol, while there is an option to use a custom AES key, there is no option to set the IV (Initialization Vector) prior to versions 5.3.2, 5.2.4, 5.1.6, and 5.0.8. The IV is set to zero and remains constant throughout the product's lifetime. In AES/CBC mode, if the IV is not properly initialized, the encrypted output becomes deterministic, leading to potential data leakage. To address the aforementioned issues, the application generates a random IV when activating the AES key starting in versions 5.3.2, 5.2.4, 5.1.6, and 5.0.8. • https://github.com/EspressifApp/EsptouchForAndroid/tree/master/esptouch-v2 https://github.com/EspressifApp/EsptouchForIOS/tree/master/EspTouchDemo/ESPTouchV2 https://github.com/espressif/esp-idf/commit/4f85a2726e04b737c8646d865b44ddd837b703db https://github.com/espressif/esp-idf/commit/8fb28dcedcc49916a5206456a3a61022d4302cd8 https://github.com/espressif/esp-idf/commit/d47ed7d6f814e21c5bc8997ab0bc68e2360e5cb2 https://github.com/espressif/esp-idf/commit/de69895f38d563e22228f5ba23fffa02feabc3a9 https://github.com/espressif/esp-idf/commit/fd224e83bbf133833638b277c767b • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-909: Missing Initialization of Resource •
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 •
CVSS: 6.1EPSS: 0%CPEs: 4EXPL: 0CVE-2024-28183 – Anti Rollback bypass with physical access and TOCTOU attack
https://notcve.org/view.php?id=CVE-2024-28183
ESP-IDF is the development framework for Espressif SoCs supported on Windows, Linux and macOS. A Time-of-Check to Time-of-Use (TOCTOU) vulnerability was discovered in the implementation of the ESP-IDF bootloader which could allow an attacker with physical access to flash of the device to bypass anti-rollback protection. Anti-rollback prevents rollback to application with security version lower than one programmed in eFuse of chip. This attack can allow to boot past (passive) application partition having lower security version of the same device even in the presence of the flash encryption scheme. The attack requires carefully modifying the flash contents after the anti-rollback checks have been performed by the bootloader (before loading the application). • https://github.com/espressif/esp-idf/commit/3305cb4d235182067936f8e940e6db174e25b4b2 https://github.com/espressif/esp-idf/commit/4c95aa445d4e84f01f86b6f3a552aa299276abf3 https://github.com/espressif/esp-idf/commit/534e3ad1fa68526a5f989fb2163856d6b7cd2c87 https://github.com/espressif/esp-idf/commit/7003f1ef0dffc73c34eb153d1b0710babb078149 https://github.com/espressif/esp-idf/commit/b2cdc0678965790f49afeb6e6b0737cd24433a05 https://github.com/espressif/esp-idf/commit/c33b9e1426121ce8cccf1a94241740be9cff68de https://github.com/espressif/esp-idf/commit/f327ddf6adab0c28d39597578572 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
