FKIE_CVE-2024-36400

Vulnerability from fkie_nvd - Published: 2024-06-04 15:15 - Updated: 2026-06-17 07:36
Severity
9.4 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
nano-id is a unique string ID generator for Rust. Affected versions of the nano-id crate incorrectly generated IDs using a reduced character set in the `nano_id::base62` and `nano_id::base58` functions. Specifically, the `base62` function used a character set of 32 symbols instead of the intended 62 symbols, and the `base58` function used a character set of 16 symbols instead of the intended 58 symbols. Additionally, the `nano_id::gen` macro is also affected when a custom character set that is not a power of 2 in size is specified. It should be noted that `nano_id::base64` is not affected by this vulnerability. This can result in a significant reduction in entropy, making the generated IDs predictable and vulnerable to brute-force attacks when the IDs are used in security-sensitive contexts such as session tokens or unique identifiers. The vulnerability is fixed in 0.4.0.

      "value": "nano-id es un generador de ID de cadena \u00fanico para Rust. Las versiones afectadas de la caja nano-id generaron identificaciones incorrectamente utilizando un conjunto de caracteres reducido en las funciones `nano_id::base62` y `nano_id::base58`. Espec\u00edficamente, la funci\u00f3n \"base62\" us\u00f3 un conjunto de caracteres de 32 s\u00edmbolos en lugar de los 62 s\u00edmbolos previstos, y la funci\u00f3n \"base58\" us\u00f3 un conjunto de caracteres de 16 s\u00edmbolos en lugar de los 58 s\u00edmbolos previstos. Adem\u00e1s, la macro `nano_id::gen` tambi\u00e9n se ve afectada cuando se especifica un conjunto de caracteres personalizado que no tiene un tama\u00f1o de potencia de 2. Cabe se\u00f1alar que `nano_id::base64` no se ve afectado por esta vulnerabilidad. Esto puede dar como resultado una reducci\u00f3n significativa de la entrop\u00eda, lo que hace que los ID generados sean predecibles y vulnerables a ataques de fuerza bruta cuando los ID se utilizan en contextos sensibles a la seguridad, como tokens de sesi\u00f3n o identificadores \u00fanicos. La vulnerabilidad se solucion\u00f3 en 0.4.0."
