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.

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.

There is a use-after-free (UAF) vulnerability in Huawei products. An attacker may craft specific packets to exploit this vulnerability. Successful exploitation may cause the service abnormal. Affected product versions include:CloudEngine 12800 V200R005C10SPC800,V200R019C00SPC800;CloudEngine 5800 V200R005C10SPC800,V200R019C00SPC800;CloudEngine 6800 V200R005C10SPC800,V200R005C20SPC800,V200R019C00SPC800;CloudEngine 7800 V200R005C10SPC800,V200R019C00SPC800.

There is an out of bounds write vulnerability in some Huawei products. An attacker can exploit this vulnerability by sending crafted data in the packet to the target device. 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.

There is an out-of-bounds read vulnerability in Huawei CloudEngine products. The software reads data past the end of the intended buffer when parsing certain PIM message, an adjacent attacker could send crafted PIM messages to the device, successful exploit could cause out of bounds read when the system does the certain operation.

There is an improper authentication vulnerability in some verisons of Huawei CloudEngine product. A module does not verify the input file properly. Attackers can exploit this vulnerability by crafting malicious files to bypass current verification mechanism. This can compromise normal service.

There is an out of bound read vulnerability in some verisons of Huawei CloudEngine product. A module does not deal with specific message properly. Attackers can exploit this vulnerability by sending malicious packet. This can lead to denial of service.

There is a privilege escalation vulnerability in some versions of CloudEngine 12800,CloudEngine 5800,CloudEngine 6800 and CloudEngine 7800. Due to insufficient input validation, a local attacker with high privilege may execute some specially crafted scripts in the affected products. Successful exploit will cause privilege escalation.

There is a information leak vulnerability in some Huawei products, and it could allow a local attacker to get information. The vulnerability is due to the improper management of the username. An attacker with the ability to access the device and cause the username information leak. Affected product versions include: CloudEngine 12800 versions V200R002C50SPC800, V200R003C00SPC810, V200R005C00SPC800, V200R005C10SPC800, V200R019C00SPC800; CloudEngine 5800 versions V200R002C50SPC800, V200R003C00SPC810, V200R005C00SPC800, V200R005C10SPC800, V200R019C00SPC800; CloudEngine 6800 versions V200R002C50SPC800, V200R003C00SPC810, V200R005C00SPC800, V200R005C10SPC800, V200R005C20SPC800, V200R019C00SPC800; CloudEngine 7800 versions V200R002C50SPC800, V200R003C00SPC810, V200R005C00SPC800, V200R005C10SPC800, V200R019C00SPC800

There is a denial of service vulnerability in some Huawei products. Due to improper memory management, memory leakage may occur in some special cases. Attackers can perform a series of operations to exploit this vulnerability. Successful exploit may cause a denial of service. Affected product versions include: CloudEngine 12800 versions V200R019C00SPC800; CloudEngine 5800 versions V200R019C00SPC800; CloudEngine 6800 versions V200R005C20SPC800, V200R019C00SPC800; CloudEngine 7800 versions V200R019C00SPC800; NE40E versions V800R011C00SPC200, V800R011C00SPC300, V800R011C10SPC100; NE40E-F versions V800R011C00SPC200, V800R011C10SPC100; NE40E-M versions V800R011C00SPC200, V800R011C10SPC100.
