CVE-2024-21530 (GCVE-0-2024-21530)

Vulnerability from cvelistv5 – Published: 2024-10-02 05:00 – Updated: 2024-10-02 13:42

Summary

Versions of the package cocoon before 0.4.0 are vulnerable to Reusing a Nonce, Key Pair in Encryption when the encrypt, wrap, and dump functions are sequentially called. An attacker can generate the same ciphertext by creating a new encrypted message with the same cocoon object. **Note:** The issue does NOT affect objects created with Cocoon::new which utilizes ThreadRng.

Severity ?

4.5 (Medium)

GHSA-6878-6WC2-PF5H

Vulnerability from github – Published: 2023-10-24 19:22 – Updated: 2025-12-29 22:23

Summary

Sequential calls of encryption API (`encrypt`, `wrap`, and `dump`) result in nonce reuse

Details

Problem: Trying to create a new encrypted message with the same cocoon object generates the same ciphertext. It mostly affects MiniCocoon and Cocoon objects with custom seeds and RNGs (where StdRng is used under the hood).

Note: The issue does NOT affect objects created with Cocoon::new which utilizes ThreadRng.

Cause: StdRng produces the same nonce because StdRng::clone resets its state.

Measure: Make encryption API mutable (encrypt, wrap, and dump).

Workaround: Create a new cocoon object with a new seed per each encryption.

How to Reproduce

let cocoon = MiniCocoon::from_password(b"password", &[1; 32]);
let mut data1 = "my secret data".to_owned().into_bytes();
let _ = cocoon.encrypt(&mut data1)?;

let mut data2 = "my secret data".to_owned().into_bytes();
let _ = cocoon.encrypt(&mut data2)?;

// data1: [23, 217, 251, 151, 179, 62, 85, 15, 253, 92, 192, 112, 200, 52]
// data2: [23, 217, 251, 151, 179, 62, 85, 15, 253, 92, 192, 112, 200, 52]

Workaround

For cocoon <= 0.3.3, create a new cocoon with a different seed per each encrypt/wrap/dump call.

let cocoon = MiniCocoon::from_password(b"password", &[1; 32]);
let mut data1 = "my secret data".to_owned().into_bytes();
let _ = cocoon.encrypt(&mut data1)?;

// Another seed: &[2; 32].
let cocoon = MiniCocoon::from_password(b"password", &[2; 32]);
let mut data2 = "my secret data".to_owned().into_bytes();
let _ = cocoon.encrypt(&mut data2)?;

// data1: [23, 217, 251, 151, 179, 62, 85, 15, 253, 92, 192, 112, 200, 52]
// data2: [53, 223, 209, 96, 130, 99, 209, 108, 83, 189, 123, 81, 19, 1]
