CVE-ID: CVE-2021-3114
CWE-ID:
CWE-682 - Incorrect Calculation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to incorrect calculation performed by the application in "crypto/elliptic/p224.go". A remote attacker can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.

2) OS Command Injection
EUVDB-ID: #VU50046
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-3115
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
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.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
