CVE-2024-21638

CWE-269Published: January 10, 2024· Updated: Jun 17, 2026

9.8
CVSS v3.1

Official Description

Azure IPAM (IP Address Management) is a lightweight solution developed on top of the Azure platform designed to help Azure customers manage their IP Address space easily and effectively. By design there is no write access to customers' Azure environments as the Service Principal used is only assigned the Reader role at the root Management Group level. Until recently, the solution lacked the validation of the passed in authentication token which may result in attacker impersonating any privileged user to access data stored within the IPAM instance and subsequently from Azure, causing an elevation of privilege. This vulnerability has been patched in version 3.0.0.

Risk Analysis

Azure IPAM failed to validate authentication tokens, allowing attackers to impersonate privileged users and access sensitive data. This critical elevation of privilege vulnerability has been addressed in version 3.0.0.

No public exploit is known for this vulnerability, and it is not in the KEV catalog. It is remotely exploitable with low attack complexity.

Recommended Action

Upgrade Azure IPAM to version 3.0.0 or later. Ensure that the service principal permissions are correctly scoped according to the principle of least privilege.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2024-21638 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
