Due to insufficient validation of message, successful exploit can cause certain service abnormal.Affected product versions include:CloudEngine 12800 versions V200R002C50SPC800,V200R003C00SPC810,V200R005C00SPC800,V200R005C10SPC800,V200R019C00SPC800,V200R019C10SPC800;CloudEngine 5800 versions V200R002C50SPC800,V200R003C00SPC810,V200R005C00SPC800,V200R005C10SPC800,V200R019C00SPC800,V200R019C10SPC800@;CloudEngine 6800 versions V200R002C50SPC800,V200R003C00SPC810,V200R005C00SPC800,V200R005C10SPC800,V200R005C20SPC800,V200R019C00SPC800,V200R019C10SPC800;CloudEngine 7800 versions V200R002C50SPC800,V200R003C00SPC810,V200R005C00SPC800,V200R005C10SPC800,V200R019C00SPC800,V200R019C10SPC800.
CVE-2021-22332
There is a pointer double free vulnerability in some versions of CloudEngine 5800, CloudEngine 6800, CloudEngine 7800 and CloudEngine 12800. When a function is called, the same memory pointer is copied to two functional modules. Attackers can exploit this vulnerability by performing a malicious operation to cause the pointer double free. This may lead to module crash, compromising normal service.
