CVE-2021-37127

There is a signature management vulnerability in some huawei products. An attacker can forge signature and bypass the signature check. During firmware update process, successful exploit this vulnerability can cause the forged system file overwrite the correct system file. Affected product versions include:iManager NetEco V600R010C00CP2001,V600R010C00CP2002,V600R010C00SPC100,V600R010C00SPC110,V600R010C00SPC120,V600R010C00SPC200,V600R010C00SPC210,V600R010C00SPC300;iManager NetEco 6000 V600R009C00SPC100,V600R009C00SPC110,V600R009C00SPC120,V600R009C00SPC190,V600R009C00SPC200,V600R009C00SPC201,V600R009C00SPC202,V600R009C00SPC210.
