Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Enforces approved authorizations for access to Azure Portal resources, directly preventing privilege escalation due to improper authorization (CWE-285).
Requires correct access control decisions for defined resources and roles, addressing the authorization flaw enabling unauthenticated attackers to escalate privileges.
Limits privileges to the minimum necessary, reducing the potential impact of escalated access gained through the Azure Portal vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct EoP via improper auth in public-facing Azure Portal enables remote exploitation for privilege escalation.
NVD Description
Azure Portal Elevation of Privilege Vulnerability
Deeper analysisAI
CVE-2025-53792 is an elevation of privilege vulnerability affecting the Azure Portal. It stems from improper authorization (CWE-285) and has a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating critical severity due to its potential for high confidentiality and integrity impacts without requiring user privileges or interaction.
Unauthenticated attackers with network access can exploit this vulnerability remotely with low complexity. Successful exploitation allows privilege escalation within the Azure Portal, enabling unauthorized access to sensitive data (high confidentiality impact) and modification of resources (high integrity impact), while availability remains unaffected.
