Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Timely application of vendor patches directly remediates the use-after-free vulnerability in lsasrv, preventing local privilege escalation.
Implements memory protection safeguards such as DEP and ASLR that directly mitigate use-after-free exploitation attempts in lsasrv.
Enforces least privilege to limit the scope and impact of privilege escalation even if the lsasrv use-after-free is exploited.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The use-after-free vulnerability in lsasrv enables local privilege escalation from low privileges, directly matching T1068 Exploitation for Privilege Escalation.
NVD Description
Use after free in Microsoft Local Security Authority Server (lsasrv) allows an authorized attacker to elevate privileges locally.
Deeper analysisAI
CVE-2025-24072 is a use-after-free vulnerability (CWE-416) in the Microsoft Local Security Authority Server (lsasrv) component. It affects Microsoft Windows operating systems and was published on 2025-03-11 with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
An authorized local attacker with low privileges (PR:L) can exploit this vulnerability through a low-complexity attack (AC:L) with no user interaction required (UI:N). Successful exploitation enables local privilege escalation, granting high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged security scope (S:U).
