EUVDB-ID: #VU62036

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-23806

CWE-ID: CWE-252 - Unchecked Return Value

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to unchecked return value within the Curve.IsOnCurve() function in crypto/elliptic. A remote attacker can force the application to incorrectly return true in situations with a big.Int value that is not a valid field element. As a result, an attacker can modify application flow, which can lead to unauthorized data modification or denial of service.

Mitigation

Install update from vendor's website.
