Privilege Escalation in Microsoft Partner Center (CVE-2024-49035)

Historical catalog analysis: CISA added this entry on February 25, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2024-49035 is an improper access control vulnerability (CWE-269) affecting Microsoft Partner Center. According to CISA, this flaw allows an attacker to escalate privileges within the environment. The vulnerability was added to the Known Exploited Vulnerabilities (KEV) catalog on February 25, 2025.

Exposure and applicability

This vulnerability applies specifically to organizations utilizing Microsoft Partner Center. Because this is a cloud-based service, exposure is tied to the identity and access management configurations of the tenant. The primary risk is the unauthorized elevation of permissions, which could allow an attacker to perform actions beyond their intended authorization level.

Remediation priorities

Based on the KEV catalog entry, remediation should be prioritized as follows:

1. Vendor Mitigation: Organizations should immediately apply mitigations according to Microsoft’s official instructions via the MSRC guide.
2. Cloud Service Guidance: For those operating under federal mandates or following similar frameworks, BOD 22-01 guidance for cloud services should be applied to ensure consistent exposure management.
3. Service Evaluation: In scenarios where vendor mitigations are unavailable or cannot be verified, organizations may need to consider discontinuing the use of the product to eliminate the risk.

How to validate remediation

Verification must move beyond a simple version check, as this is a cloud service managed by the provider. To verify that exposure has been reduced, defenders should:

• Confirm Mitigation Application: Verify through vendor-provided dashboards or official notifications that the specific mitigations for CVE-2024-49035 have been applied to the tenant.
• Audit Privilege Changes: Review audit logs for any unexpected privilege escalations or unauthorized changes to administrative roles within Partner Center that occurred prior to and following the mitigation.
• Access Review: Perform a targeted review of high-privilege accounts to ensure no unauthorized accounts gained elevated permissions during the window of vulnerability.

Limits and open questions

While CISA has flagged this as known to be exploited, the specific status regarding use in ransomware campaigns remains unknown. Furthermore, because the service is cloud-hosted, the exact internal mechanism of the improper access control is not detailed in the KEV entry; defenders are dependent on Microsoft’s MSRC documentation for technical specifics. Applying mitigations could reduce the likelihood of exploitation, but residual risk may remain if existing accounts were already compromised and privileges escalated before the fix was implemented.
