CVE-2024-47211
Description
A flaw was found in OpenStack Ironic. The lack of checksum verification allows an attacker with access to the images to modify an image without the change noticed by OpenStack. This issue leads to integrity issues in the image.
Statement
This vulnerability is classified as moderate severity rather than important because it requires a specific set of conditions for exploitation. An attacker must have access to the image source and be positioned to intercept or modify images during their transmission, which limits the attack surface to environments with insecure or untrusted network configurations. Additionally, the vulnerability only impacts Ironic when it is configured to convert images to raw format for streaming, making it a less common scenario. The absence of checksum validation could compromise image integrity, but it does not grant direct control over the system or immediate escalation of privileges, hence the moderate classification.
Red Hat OpenStack 16.2 is not affected by this vulnerability, as it doesn't contain the affected code and the needed configuration option required to a successful exploit.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
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).

Understanding the Weakness (CWE)
Integrity,Other
Technical Impact: Modify Application Data; Other
Integrity checks usually use a secret key that helps authenticate the data origin. Skipping integrity checking generally opens up the possibility that new data from an invalid source can be injected.
Integrity,Other
Technical Impact: Other
Data that is parsed and used may be corrupted.
Non-Repudiation,Other
Technical Impact: Hide Activities; Other
Without a checksum check, it is impossible to determine if any changes have been made to the data after it was sent.
