Performing a manipulation results in covert timing channel. This vulnerability is known as CVE-2023-49092. Remote exploitation of the attack is possible. No exploit is available.

Detailsinfo

A vulnerability was found in RustCrypto RSA up to 0.9.5. It has been classified as problematic. This affects an unknown functionality. The manipulation with an unknown input leads to a covert timing channel vulnerability. CWE is classifying the issue as CWE-385. Covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information. This is going to have an impact on confidentiality. The summary by CVE is:

RustCrypto/RSA is a portable RSA implementation in pure Rust. Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. There is currently no fix available. As a workaround, avoid using the RSA crate in settings where attackers are able to observe timing information, e.g. local use on a non-compromised computer.

The weakness was published 11/29/2023 as 19. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2023-49092 since 11/21/2023. Neither technical details nor an exploit are publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
