CVE-2019-12588
6.5 · MEDIUMOverview
CVE-2019-12588 is a medium-severity vulnerability affecting espressif arduino_esp8266. It was published on September 4, 2019 and has a CVSS 3.1 base score of 6.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The client 802.11 mac implementation in Espressif ESP8266_NONOS_SDK 2.2.0 through 3.1.0 does not validate correctly the RSN AuthKey suite list count in beacon frames, probe responses, and association responses, which allows attackers in radio range to cause a denial of service (crash) via a crafted message.
Remediation
Check the references section for vendor advisories and patches from espressif. Update arduino_esp8266 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
