CVE-2024-33453: 
Espressif ESP-IDF Tools vulnerability analysis and mitigation

A Buffer Overflow vulnerability exists in esp-idf version 5.1 that allows a remote attacker to obtain sensitive information through the externalId component. The vulnerability was discovered and disclosed on October 17, 2024, and affects esp-idf framework systems (NVD, CVE).

The vulnerability is classified as a Classic Buffer Overflow (CWE-120) that occurs in the externalId component. The CVSS v3.1 base score is 8.1 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N, indicating a network-accessible vulnerability with low attack complexity requiring low privileges and no user interaction (NVD).

The vulnerability allows remote attackers to obtain sensitive information through improper object-level access control. When successfully exploited, it enables unauthorized access to sensitive data by manipulating the id parameter linked to the externalId component (GitHub).

To mitigate this vulnerability, it is recommended to implement robust object-level access controls within the esp-idf framework to restrict access based on user roles and permissions. Additionally, proper validation and sanitization of user inputs should be implemented, particularly for URL parameters like id that could control access to sensitive information (GitHub).
