Huawei CloudEngine 12800 up to V100R006C00 IPFPM Packet integer overflow

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.

A vulnerability was found in Huawei CloudEngine 5800, CloudEngine 6800, CloudEngine 7800, CloudEngine 8800 and CloudEngine 12800 up to V100R006C00 (Cloud Software) and classified as problematic. This issue affects an unknown part of the component IPFPM Packet Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is availability. The summary by CVE is:

Huawei CloudEngine 12800 with software V100R002C00, V100R003C00, V100R003C10, V100R005C00, V100R005C10, V100R006C00; CloudEngine 5800 with software V100R002C00, V100R003C00, V100R003C10, V100R005C00, V100R005C10, V100R006C00; CloudEngine 6800 with software V100R002C00, V100R003C00, V100R003C10, V100R005C00, V100R005C10, V100R006C00; CloudEngine 7800 with software V100R003C00, V100R003C10, V100R005C00, V100R005C10, V100R006C00; CloudEngine 8800 with software V100R006C00; and Secospace USG6600 with software V500R001C00 allow remote unauthenticated attackers to craft specific IPFPM packets to trigger an integer overflow and cause the device to reset.
