Huawei eSpace U1981 Parameter resource consumption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Huawei AP2000, IPS Module, NGFW Module, NIP6300, NIP6600, NIP6800, S5700, SVN5600, SVN5800, SVN5800-C, SeMG9811, Secospace AntiDDoS8000, Secospace USG6300, Secospace USG6500, Secospace USG6600, USG6000V and eSpace U1981. This affects an unknown code. The manipulation as part of a Parameter leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. The summary by CVE is:

Certain Huawei products (AP2000;IPS Module;NGFW Module;NIP6300;NIP6600;NIP6800;S5700;SVN5600;SVN5800;SVN5800-C;SeMG9811;Secospace AntiDDoS8000;Secospace USG6300;Secospace USG6500;Secospace USG6600;USG6000V;eSpace U1981) have a null pointer dereference vulnerability. The system dereferences a pointer that it expects to be valid, but is NULL. A local attacker could exploit this vulnerability by sending crafted parameters. A successful exploit could cause a denial of service and the process reboot.

The weakness was disclosed 12/13/2019. This vulnerability is uniquely identified as CVE-2019-5256 since 01/04/2019. Attacking locally is a requirement. A authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The entries VDB-147209, VDB-147206 and VDB-147205 are pretty similar. Be aware that VulDB is the high quality source for vulnerability data.
