CVE-2023-4785

2023-09-13
Severity Assessment
7.5
HIGH
CVSS v3.x Score
Clinical Analysis (Description)

Lack of error handling in the TCP server in Google's gRPC starting version 1.23 on posix-compatible platforms (ex. Linux) allows an attacker to cause a denial of service by initiating a significant number of connections with the server. Note that gRPC C++ Python, and Ruby are affected, but gRPC Java, and Go are NOT affected.
