CVE-2021-22357

There is a denial of service vulnerability in Huawei products. A module cannot deal with specific messages due to validating inputs insufficiently. Attackers can exploit this vulnerability by sending specific messages to affected module. This can cause denial of service. Affected product versions include: S12700 V200R013C00SPC500, V200R019C00SPC500; S5700 V200R013C00SPC500, V200R019C00SPC500; S6700 V200R013C00SPC500, V200R019C00SPC500; S7700 V200R013C00SPC500, V200R019C00SPC500.
