Summary
Devolutions.XTS.NET Vulnerable to Timing Attack on GF Multiplications
Workarounds
Upgrade the package
References
Impact
Timing attacks on Galois Field multiplications in this package. Successful exploitation would effectively allow a downgrade of the security guarantees of the XTS mode to the security guarantees of ECB mode, allowing block swapping, enabling identification of identical blocks, and rendering half of the XTS key obsolete. Timing attacks require specific conditions to be exploitable.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2024-11862? CVE-2024-11862 is a medium-severity security vulnerability in Devolutions.XTS.NET (nuget), affecting versions < 2024.11.26. It is fixed in 2024.11.26.
- Which versions of Devolutions.XTS.NET are affected by CVE-2024-11862? Devolutions.XTS.NET (nuget) versions < 2024.11.26 is affected.
- Is there a fix for CVE-2024-11862? Yes. CVE-2024-11862 is fixed in 2024.11.26. Upgrade to this version or later.
- Is CVE-2024-11862 exploitable, and should I be worried? Whether CVE-2024-11862 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-11862 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
