Risk: High
CVSSv3.1:
CVE-ID: CVE-2021-3115
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when using the "go get" command to fetch modules that make use of cgo. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system.
