The SIP module of some Huawei products have a denial of service (DoS) vulnerability. A remote attacker could exploit these three vulnerabilities by sending the specially crafted messages to the affected device. Due to the insufficient verification of the packets, successful exploit could allow the attacker to cause buffer overflow and dead loop, leading to DoS condition. Affected products can be found in https://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-sip-en.

Huawei products Secospace USG6300;USG6300E with versions of V500R001C30,V500R001C50,V500R001C60,V500R001C80,V500R005C00,V500R005C10;V600R006C00 have a vulnerability of insufficient input verification. An attacker with limited privilege can exploit this vulnerability to access a specific directory. Successful exploitation of this vulnerability may lead to information leakage.

Huawei CloudLink Board version 20.0.0; DP300 version V500R002C00; RSE6500 versions V100R001C00, V500R002C00, and V500R002C00SPC900; and TE60 versions V500R002C00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C10, V600R019C00, and V600R019C00SPC100 have an information leak vulnerability. An unauthenticated, remote attacker can make a large number of attempts to guess information. Successful exploitation may cause information leak.

There is an integer overflow vulnerability in LDAP client of some Huawei products. Due to insufficient input validation, a remote attacker could exploit this vulnerability by sending malformed packets to the target devices. Successful exploit could cause the affected system crash.

Huawei CloudUSM-EUA V600R006C10;V600R019C00 have an information leak vulnerability. Due to improper configuration, the attacker may cause information leak by successful exploitation.

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.

The SIP TLS module of Huawei CloudLink Phone 7900 with V600R019C10 has a TLS certificate verification vulnerability. Due to insufficient verification of specific parameters of the TLS server certificate, attackers can perform man-in-the-middle attacks, leading to the affected phones registered abnormally, affecting the availability of IP phones.

There is an integer overflow vulnerability in LDAP server of some Huawei products. Due to insufficient input validation, a remote attacker could exploit this vulnerability by sending malformed packets to the target devices. Successful exploit could cause the affected system crash.
