CVE-2024-21530
CVE-2024-21530 affects the cocoon package before version 0.4.0, exposing a critical encryption vulnerability. This flaw involves the reusing of a nonce and key pair, leading to the generation of identical ciphertexts when encrypt, wrap, and dump functions are called sequentially. An attacker can exploit this by recreating the same encrypted message using the same cocoon object, compromising data security.
Although the CVSS score is 0, indicating no immediate impact, the SVRS score of 30, while not critical, still warrants attention, as the flaw allows for potential ciphertext duplication if exploited. This highlights the importance of updating to cocoon version 0.4.0 or later to mitigate this risk. The vulnerability poses a risk to applications relying on cocoon for secure data handling, as encrypted information may not be as protected as expected due to potential decryption using reused keys. Users should prioritize patching to prevent unintended data exposure.
Description
CVE-2024-21530 is a vulnerability in the cocoon package before version 0.4.0. It allows an attacker to generate the same ciphertext by creating a new encrypted message with the same cocoon object. This could allow an attacker to decrypt or forge messages that are encrypted using the vulnerable package.
Key Insights
- The vulnerability is rated as 4.5 on the CVSS scale, indicating a medium severity.
- The SVRS score of 38 indicates that the vulnerability is not critical and does not require immediate action.
- The vulnerability is not currently being exploited in the wild.
- No specific threat actors or APT groups have been identified as actively exploiting the vulnerability.
Mitigation Strategies
- Upgrade to cocoon version 0.4.0 or later.
- Avoid using the encrypt, wrap, and dump functions sequentially with the same cocoon object.
- Use a different encryption library that is not vulnerable to this attack.
