CVE-2024-48930

Estado: AplazadaAlta (8.7)—

secp256k1-node is a Node.js binding for an Optimized C library for EC operations on curve secp256k1. In `elliptic`-based version, `loadUncompressedPublicKey` has a check that the public key is on the curve. Prior to versions 5.0.1, 4.0.4, and 3.8.1, however, `loadCompressedPublicKey` is missing that check. That allows the attacker to use public keys on low-cardinality curves to extract enough information to fully restore the private key from as little as 11 ECDH sessions, and very cheaply on compute power.

Other operations on public keys are also affected, including e.g. `publicKeyVerify()` incorrectly returning `true` on those invalid keys, and e.g. `publicKeyTweakMul()` also returning predictable outcomes allowing to restore the tweak. Versions 5.0.1, 4.0.4, and 3.8.1 contain a fix for the issue.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CVE en librería de criptografía accesible remotamente (AV:N, PR:N). Permite extraer claves privadas de sesiones ECDH explotando validación ausente en claves comprimidas, comprometiendo secretos compartidos.

Otras operaciones en claves públicas también se ven afectadas, incluyendo, por ejemplo, `publicKeyVerify()` que devuelve incorrectamente `true` en esas claves no válidas, y, por ejemplo, `publicKeyTweakMul()` que también devuelve resultados predecibles que permiten restaurar el ajuste.
