CVE-2022-4134
Description
A flaw was found in openstack-glance. This issue could allow a remote, authenticated attacker to tamper with images, compromising the integrity of virtual machines created using these modified images.
Statement
You must be using Ceph as a backend to be affected by this flaw.
As this flaw would involve significant architectural changes, the impact is moderate. A fix will not be produced for Red Hat OpenStack Platform 16.2 and older releases. If you are concerned about the risk of this flaw against your environment, please follow guidance in the mitigation section, but understand this comes with performance tradeoffs.
Mitigation
There are two options:
1. Manually disable the show_multiple_locations configuration setting (change it to false).
2. Keep show_multiple_locations enabled, but restrict the glance-api service from being exposed directly to end users. Refer the upstream OSSN listed in the external references section for further details.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability
Technical Impact: Execute Unauthorized Code or Commands
An attacker could insert malicious functionality into the program by causing the program to download code that the attacker has placed into the untrusted control sphere, such as a malicious web site. This could enable the injection of malware, information exposure by granting excessive privileges or permissions to the untrusted functionality, DOM-based XSS vulnerabilities, stealing user's cookies, open redirect to malware (CWE-601), etc.
