Description
This security bulletin contains information about 2 vulnerabilities.
1) Improper verification of cryptographic signature (CVE-ID: CVE-2024-48948)
CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect validation of valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. Such behavior leads to valid signatures being rejected.
2) Input validation error (CVE-ID: CVE-2024-48949)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of user-supplied input within the verify() function in lib/elliptic/eddsa/index.js. A remote attacker can send specially crafted input to the application and bypass implemented security restrictions.
