FKIE_CVE-2021-22309

Vulnerability from fkie_nvd - Published: 2021-03-22 18:15 - Updated: 2026-06-17 03:36
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
There is insecure algorithm vulnerability in Huawei products. A module uses less random input in a secure mechanism. Attackers can exploit this vulnerability by brute forcing to obtain sensitive message. This can lead to information leak. Affected product versions include:USG9500 versions V500R001C30SPC200, V500R001C60SPC500,V500R005C00SPC200;USG9520 versions V500R005C00;USG9560 versions V500R005C00;USG9580 versions V500R005C00.
