How severe is CVE-2024-11862?

No CVSS score has been assigned to CVE-2024-11862 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2024-11862?

CVE-2024-11862 affects the following packages: Devolutions.XTS.NET (NuGet). Ecosystems affected: NuGet.

How do I fix CVE-2024-11862?

Update Devolutions.XTS.NET to 2024.11.26 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-11862 is resolved across your whole dependency graph.

How do I detect CVE-2024-11862 in my NuGet dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Devolutions.XTS.NET, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-11862 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2024-11862 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-11862 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-11862?

CVE-2024-11862 has an EPSS (Exploit Prediction Scoring System) score of 0.1%, placing it in the 3th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-11862?

CVE-2024-11862 is classified as CWE-385 (CWE-385). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2024-11862 published, and has it been updated?

CVE-2024-11862 was published on November 27, 2024 and was last updated on November 27, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

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.
