CVE-2024-29059 Microsoft CVE debrief

Who should care

Security teams and administrators responsible for Windows systems that use Microsoft .NET Framework, especially environments that rely on vendor patching and mitigation workflows. Priority should be highest for internet-facing, business-critical, or widely deployed systems.

Technical summary

The supplied corpus identifies the issue as an information disclosure vulnerability in Microsoft .NET Framework. Beyond that classification, the provided sources do not include CVSS data, affected versions, exploit conditions, or impact specifics. The key operational fact is that CISA lists it in KEV and points defenders to Microsoft’s update guidance.

Defensive priority

High. CISA added the vulnerability to KEV on 2025-02-04 and set a remediation due date of 2025-02-25. Follow Microsoft’s mitigation or update guidance promptly; if mitigations are unavailable, CISA’s guidance is to discontinue use of the product.

Recommended defensive actions

• Review Microsoft’s advisory for CVE-2024-29059 and apply the recommended mitigations or updates.
• Inventory systems running Microsoft .NET Framework so remediation can be tracked to completion.
• Prioritize internet-facing, high-value, and broadly deployed assets for validation and patching.
• Verify that mitigations remain in place after maintenance and configuration changes.
• If Microsoft’s mitigations are unavailable in a given environment, follow CISA guidance and discontinue use of the product or component until a safe remediation path exists.

Evidence notes

This debrief uses only the supplied corpus: the CISA KEV entry identifies Microsoft as the vendor, .NET Framework as the product, and states the vulnerability name, date added (2025-02-04), and due date (2025-02-25). The corpus also references the Microsoft MSRC advisory and NVD record, but no further technical details were provided here. No CVSS score was supplied.

Methodology and review provenance

AI-assisted synthesis based on stored public vulnerability evidence. System validation, approval state, and publication status do not by themselves establish human review of this revision. PatchSiren helps prioritize defensive review and does not prove exposure or remediation on any system.
