CVE-2021-22309

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.
