Overview

CVE-2022-22187 is a high-severity vulnerability. It was published on April 14, 2022 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

An Improper Privilege Management vulnerability in the Windows Installer framework used in the Juniper Networks Juniper Identity Management Service (JIMS) allows an unprivileged user to trigger a repair operation. Running a repair operation, in turn, will trigger a number of file operations in the %TEMP% folder of the user triggering the repair. Some of these operations will be performed from a SYSTEM context (started via the Windows Installer service), including the execution of temporary files. An attacker may be able to provide malicious binaries to the Windows Installer, which will be executed with high privilege, leading to a local privilege escalation. This issue affects Juniper Networks Juniper Identity Management Service (JIMS) versions prior to 1.4.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
