Detailsinfo

A vulnerability was found in Huawei Product (Smartphone Operating System) (the affected version unknown). It has been classified as problematic. This affects an unknown part of the component MPLS Echo Request Message Handler. The manipulation as part of a Parameter leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on availability. The summary by CVE is:

Some Huawei products have a buffer error vulnerability. An unauthenticated, remote attacker could send specific MPLS Echo Request messages to the target products. Due to insufficient input validation of some parameters in the messages, successful exploit may cause the device to reset.

The weakness was presented 01/03/2020. This vulnerability is uniquely identified as CVE-2019-5304 since 01/04/2019. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.
