Description

Out-of-bounds write in Azure Monitor Agent allows an authorized attacker to execute code over a network.

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly mitigates the out-of-bounds write vulnerability by requiring timely flaw remediation through patching the Azure Monitor Agent as advised by Microsoft.

prevent

Implements memory protection mechanisms such as DEP, ASLR, and stack canaries that prevent exploitation of out-of-bounds writes for remote code execution.

prevent

Validates network inputs to the Azure Monitor Agent to prevent malformed data from triggering the out-of-bounds write condition.

Security SummaryAI

CVE-2025-62550 is an out-of-bounds write vulnerability, associated with CWE-131 and CWE-787, affecting the Azure Monitor Agent. Published on 2025-12-09, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low attack complexity, and significant impacts on confidentiality, integrity, and availability.

An authorized attacker with low privileges (PR:L) can exploit this vulnerability over the network without user interaction. Successful exploitation allows remote code execution, enabling full compromise of the affected system.

The Microsoft Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-62550 provides details on patches and mitigation guidance.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
Why these techniques?

Out-of-bounds write in Azure Monitor Agent enables low-privileged remote attackers to achieve RCE with high-impact privileges, directly facilitating T1068 (Exploitation for Privilege Escalation) and T1210 (Exploitation of Remote Services).
