In Spring Framework versions 5.3.0 - 5.3.18, 5.2.0 - 5.2.20, and older unsupported versions, the patterns for disallowedFields on a DataBinder are case sensitive. This means a field is not effectively protected unless it is listed with both upper and lower case for the first character of the field, including upper and lower case for the first character of all nested fields within the property path.
The CVSS score for this vulnerability is 5.3, indicating a medium severity. This classification is significant as it implies that organizations may face potential data integrity issues, particularly if sensitive data is exposed due to incorrect casing in field names.
Risk to organizations includes unauthorized access, potential data manipulation, and the possibility of further exploitation if the vulnerability is not addressed. Organizations should prioritize patching to mitigate these risks.
As of the latest information, this vulnerability is known to have a public proof of concept available on GitHub, and organizations should monitor for any signs of exploitation actively leveraging this vulnerability.
Organizations should address this vulnerability in their priority patch cycle.
Vulnerability Details
The official description of CVE-2022-22968 states that in the affected versions of the Spring Framework, the case sensitivity issue with DataBinder’s disallowedFields can lead to improper security controls.
This vulnerability is categorized under CWE-178, which involves improper handling of case-sensitive fields. The CVSS 3.1 score reflects a low attack complexity with no privileges required or user interaction necessary.
The affected components include various versions of the Spring Framework, and the vulnerability was published on April 14, 2022.
Technical Analysis
The root cause of this vulnerability lies in the case sensitivity of field names within the Spring Framework's DataBinder. This design flaw allows attackers to manipulate data bindings if the case is not consistently enforced.
The attack vector is network-based, with low complexity, meaning that an attacker can exploit this vulnerability without significant effort. No privileges are required to exploit this vulnerability, and there is no user interaction needed to trigger it.
The impact of an exploit would primarily affect data integrity, allowing unauthorized changes to be made without detection.
Risk & Impact Analysis
Organizations using vulnerable versions of the Spring Framework must evaluate their exposure to this risk. Given the ease of exploitation and the potential for data integrity issues, the urgency for remediation is high.
The blast radius for this vulnerability could be significant, especially for applications that rely heavily on data binding processes. If exploited, attackers could leverage this flaw to manipulate application behavior or access sensitive information.
Organizations should prioritize remediation based on the CVSS score and the potential for active exploitation, as indicated by the public proof of concept available.
