Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the permissive list of allowed inputs in Microsoft Purview by requiring validation of all information inputs to prevent privilege escalation.
Enforces logical access controls to block unauthorized privilege elevation enabled by improperly validated inputs over the network.
Applies least privilege to minimize the privileges available for escalation by a high-privilege attacker exploiting permissive inputs.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct privilege escalation via permissive input validation flaw in a network-accessible service.
NVD Description
Permissive list of allowed inputs in Microsoft Purview allows an authorized attacker to elevate privileges over a network.
Deeper analysisAI
CVE-2025-53762 is a vulnerability in Microsoft Purview caused by a permissive list of allowed inputs, classified under CWE-183. Published on 2025-07-18T17:15:44.400, it carries a CVSS v3.1 base score of 8.7 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N). The flaw affects Microsoft Purview, enabling an authorized attacker to elevate privileges over a network.
An attacker with high privileges (PR:H) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation leads to privilege elevation, resulting in high confidentiality and integrity impacts (C:H/I:H) across a changed scope (S:C), with no availability impact (A:N).
