CVE-2024-35260
📋 TL;DR
This CVE describes an untrusted search path vulnerability in Microsoft Dataverse that allows authenticated attackers to execute arbitrary code over a network connection. Attackers can potentially gain control of affected systems by manipulating search paths to load malicious libraries. Organizations using Microsoft Dataverse with network connectivity are affected.
💻 Affected Systems
- Microsoft Dataverse
📦 What is this software?
Power Platform by Microsoft
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise leading to data theft, lateral movement across the network, ransomware deployment, and complete loss of confidentiality, integrity, and availability.
Likely Case
Privilege escalation leading to unauthorized access to sensitive data within Dataverse, potential data exfiltration, and limited lateral movement within the affected environment.
If Mitigated
Attack blocked at authentication layer or network segmentation prevents successful exploitation, resulting in no impact beyond failed authentication attempts.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of the target environment's configuration
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Microsoft Security Update Guide for specific patch versions
Vendor Advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-35260
Restart Required: Yes
Instructions:
1. Review Microsoft Security Update Guide for CVE-2024-35260
2. Apply the latest security updates for Microsoft Dataverse
3. Restart affected services/systems as required
4. Verify patch installation through version checking
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to Dataverse instances to only trusted sources and required administrative connections
Authentication Hardening
allImplement strong authentication controls and monitor for suspicious authentication attempts
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Dataverse instances from untrusted networks
- Enhance authentication monitoring and implement multi-factor authentication for all Dataverse access
🔍 How to Verify
Check if Vulnerable:
Check Dataverse version against Microsoft's patched versions in the security advisoryCheck Version:
Check through Microsoft Dataverse administration interface or PowerShell: Get-Command -Module Microsoft.PowerApps.Administration.PowerShellVerify Fix Applied:
Verify Dataverse version matches or exceeds the patched version specified by Microsoft📡 Detection & Monitoring
