CVE-2021-22321
Estado: ModificadaMedia (5.3)—
There is a use-after-free vulnerability in a Huawei product. A module cannot deal with specific operations in special scenarios. Attackers can exploit this vulnerability by performing malicious operations. This can cause memory use-after-free, compromising normal service. Affected product include some versions of NIP6300, NIP6600, NIP6800, S1700, S2700, S5700, S6700 , S7700, S9700, Secospace USG6300, Secospace USG6500, Secospace USG6600 and USG9500.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
- Puntuación base: 5.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.71%
- Percentil entre todas las CVEs puntuadas: 52
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
