CVE-2021-22356
Estado: ModificadaMedia (5.9)—
There is a weak secure algorithm vulnerability in Huawei products. A weak secure algorithm is used in a module. Attackers can exploit this vulnerability by capturing and analyzing the messages between devices to obtain information. This can lead to information leak.Affected product versions include: IPS Module V500R005C00SPC100, V500R005C00SPC200; NGFW Module V500R005C00SPC100, V500R005C00SPC200; Secospace USG6300 V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, V500R005C00SPC100, V500R005C00SPC200; Secospace USG6500 V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, V500R005C00SPC100, V500R005C00SPC200; Secospace USG6600 V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, V500R005C00SPC100, V500R005C00SPC200; USG9500 V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, V500R005C00SPC100, V500R005C00SPC200.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
- Puntuación base: 5.9
