Summaryinfo

A vulnerability was found in viz-rs nano-id up to 0.3.x. It has been classified as problematic. Affected by this vulnerability is the function nano_id::base58/nano_id::base62. Performing a manipulation results in entropy. This vulnerability is cataloged as CVE-2024-36400. It is possible to initiate the attack remotely. There is no exploit available. Upgrading the affected component is recommended.

Detailsinfo

A vulnerability, which was classified as critical, was found in viz-rs nano-id up to 0.3.x. This affects the function nano_id::base58/nano_id::base62. The manipulation with an unknown input leads to a entropy vulnerability. CWE is classifying the issue as CWE-331. The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2024-36400 since 05/27/2024. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

Upgrading to version 0.4.0 eliminates this vulnerability.
