CVE-2020-1861
CloudEngine 12800 with versions of V200R001C00SPC600,V200R001C00SPC700,V200R002C01,V200R002C50SPC800,V200R002C50SPC800PWE,V200R003C00SPC810,V200R003C00SPC810PWE,V200R005C00SPC600,V200R005C00SPC800,V200R005C00SPC800PWE,V200R005C10,V200R005C10SPC300 have an information leakage vulnerability in some Huawei products. In some special cases, an authenticated attacker can exploit this vulnerability because the software processes data improperly. Successful exploitation may lead to information leakage.
CVE-2019-5248
CloudEngine 12800 has a DoS vulnerability. An attacker of a neighboring device sends a large number of specific packets. As a result, a memory leak occurs after the device uses the specific packet. As a result, the attacker can exploit this vulnerability to cause DoS attacks on the target device.
CVE-2021-40042
There is a release of invalid pointer vulnerability in some Huawei products, successful exploit may cause the process and service abnormal. Affected product versions include: CloudEngine 12800 V200R019C10SPC800, V200R019C10SPC900; CloudEngine 5800 V200R019C10SPC800, V200R020C00SPC600; CloudEngine 6800 versions V200R019C10SPC800, V200R019C10SPC900, V200R020C00SPC600, V300R020C00SPC200; CloudEngine 7800 V200R019C10SPC800.
CVE-2021-40033
There is an information exposure vulnerability on several Huawei Products. The vulnerability is due to that the software does not properly protect certain information. Successful exploit could cause information disclosure. Affected product versions include: CloudEngine 12800 V200R005C10SPC800; CloudEngine 5800 V200R005C10SPC800, V200R019C00SPC800; CloudEngine 6800 V200R005C10SPC800, V200R005C20SPC800, V200R019C00SPC800; CloudEngine 7800 V200R005C10SPC800, V200R019C00SPC800.
CVE-2021-40008
There is a memory leak vulnerability in CloudEngine 12800 V200R019C00SPC800, CloudEngine 5800 V200R019C00SPC800, CloudEngine 6800 V200R019C00SPC800 and CloudEngine 7800 V200R019C00SPC800. The software does not sufficiently track and release allocated memory while parse a series of crafted binary messages, which could consume remaining memory. Successful exploit could cause memory exhaust.
