CVE-2025-32801 (GCVE-0-2025-32801)

Vulnerability from cvelistv5

Published

2025-05-28 17:03

Modified

2025-05-28 17:33

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-94 - Improper Control of Generation of Code ('Code Injection')

Summary

Kea configuration and API directives can be used to load a malicious hook library. Many common configurations run Kea as root, leave the API entry points unsecured by default, and/or place the control sockets in insecure paths. This issue affects Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.
