FKIE_CVE-2020-15720

Vulnerability from fkie_nvd - Published: 2020-07-14 14:15 - Updated: 2024-11-21 05:06
Severity ?
6.8 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N
Summary
In Dogtag PKI through 10.8.3, the pki.client.PKIConnection class did not enable python-requests certificate validation. Since the verify parameter was hard-coded in all request functions, it was not possible to override the setting. As a result, tools making use of this class, such as the pki-server command, may have been vulnerable to Person-in-the-Middle attacks in certain non-localhost use cases. This is fixed in 10.9.0-b1.

Como el par\u00e1metro de verificaci\u00f3n estaba embebido en todas las funciones de petici\u00f3n, no fue posible anular la configuraci\u00f3n. Como resultado, las herramientas que utilizan esta clase, tal y como el comando pki-server, pueden haber sido vulnerables a ataques de tipo Person-in-the-Middle en determinados casos de uso de un no localhost. Esto es corregido en la versi\u00f3n 10.9.0-b1"
