CVE-2024-36400 (GCVE-0-2024-36400)

Vulnerability from cvelistv5 – Published: 2024-06-04 14:11 – Updated: 2024-08-02 03:37

Title

nano-id is unable to generate the correct character set

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.

GHSA-9HC7-6W9R-WJ94

Vulnerability from github – Published: 2024-06-04 18:40 – Updated: 2024-06-17 15:09

Summary

Unable to generate the correct character set

Details

Reduced entropy due to inadequate character set usage

Description

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.

Impact

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.

Patches

The flaws were corrected in commit a9022772b2f1ce38929b5b81eccc670ac9d3ab23 by updating the the nano_id::gen macro to use all specified characters correctly.

PoC

use std::collections::BTreeSet;

fn main() {
    test_base58();
    test_base62();
}

fn test_base58() {
    let mut produced_symbols = BTreeSet::new();

    for _ in 0..100_000 {
        let id = nano_id::base58::<10>();
        for c in id.chars() {
            produced_symbols.insert(c);
        }
    }

    println!(
        "{} symbols generated from nano_id::base58",
        produced_symbols.len()
    );
}

fn test_base62() {
    let mut produced_symbols = BTreeSet::new();

    for _ in 0..100_000 {
        let id = nano_id::base62::<10>();
        for c in id.chars() {
            produced_symbols.insert(c);
        }
    }

    println!(
        "{} symbols generated from nano_id::base62",
        produced_symbols.len()
    );
}

      "value": "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."
