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.

Some Huawei products RSE6500 V500R002C00; SoftCo V200R003C20SPCb00; VP9660 V600R006C10; eSpace U1981 V100R001C20; V200R003C20; V200R003C30; V200R003C50 have a weak algorithm vulnerability. To exploit the vulnerability, a remote, unauthenticated attacker has to capture TLS traffic between clients and the affected products. The attacker may launch the Bleichenbacher attack on RSA key exchange to decrypt the session key and the previously captured sessions by some cryptanalytic operations. Successful exploit may cause information leak.
