CVE-2025-32801
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
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.
Affected Software
| Vendor | Product | Version Range | Status |
|---|---|---|---|
| ISC | Kea | 2.4.0 <= 2.4.1 | affected |
| ISC | Kea | 2.6.0 <= 2.6.2 | affected |
| ISC | Kea | 2.7.0 <= 2.7.8 | affected |
Weaknesses
- CWE-94: CWE-94 Improper Control of Generation of Code ('Code Injection')
Workarounds
Two mitigation approaches are possible: (1) Disable the Kea API entirely, by (1a) disabling the kea-ctrl-agent, and (1b) removing any "control-socket" stanzas from the Kea configuration files; or (2) Secure access to the API by (2a) requiring authentication (a password or client certificate) for the kea-ctrl-agent, and (2b) configuring all "control-socket" stanzas to use a directory restricted to only trusted users.
