Detailsinfo

A vulnerability was found in HPE EdgeConnect SD-WAN up to 9.4.8.2/9.5.8.1/9.6.3.1/9.7.0.0. It has been classified as very critical. Affected is an unknown code of the component Proxy Packet Processing. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A vulnerability exists in the proxy packet processing logic of the affected component where it improperly processes malformed or truncated input. An unauthenticated remote attacker could exploit this vulnerability by providing specially crafted input that triggers an integer overflow. Successful exploitation could result in a buffer overflow, potentially leading to remote code execution or denial-of-service.
