CVE-2022-31679 is a low-severity vulnerability associated with VMware's Spring Data REST, specifically impacting versions 3.6.0 - 3.5.5, 3.7.0 - 3.7.2, and older unsupported versions. This vulnerability allows applications that permit HTTP PATCH access to resources exposed by Spring Data REST to be vulnerable to exploitation. If an attacker is knowledgeable about the structure of the underlying domain model, they can craft HTTP requests that may expose hidden entity attributes.
The CVSS score of 3.7 categorizes this vulnerability as low severity, emphasizing that while it is not immediately critical, it poses a risk to organizations if left unaddressed. The risk to organizations includes potential unauthorized access to sensitive information, which could lead to data breaches or privacy violations.
Currently, there is no known public exploit for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should prioritize patching this vulnerability during their next patch cycle to mitigate any potential risks associated with its exploitation.
Given its characteristics, organizations that rely on VMware Spring Data REST should remain vigilant and address this vulnerability in a timely manner to protect their applications and data integrity.
Vulnerability Details
The official description of CVE-2022-31679 states that applications allowing HTTP PATCH access to resources exposed by Spring Data REST may expose hidden entity attributes if attackers know the structure of the underlying domain model. The vulnerability affects VMware's Spring Data REST in versions 3.6.0 - 3.5.5 and 3.7.0 - 3.7.2, as well as older unsupported versions.
As noted, the CVSS score is 3.7, indicating a low severity level. The attack vector is classified as NETWORK, and the attack complexity is HIGH, meaning that exploiting this vulnerability requires significant knowledge of the system's configuration and may not be straightforward. There are no privileges required for exploitation, and user interaction is not necessary.
The confidentiality impact is LOW, indicating that sensitive information may be exposed, while there is no integrity or availability impact. This vulnerability was published on September 21, 2022, and is classified under CWE with no specific details provided.
Technical Analysis
The root cause of this vulnerability is the misconfiguration in applications that allow HTTP PATCH requests without sufficient validation of the data being modified. Attackers can leverage this misconfiguration by crafting specific HTTP requests that manipulate or access hidden entity attributes.
The attack vector is NETWORK, allowing attackers to exploit the vulnerability remotely without needing physical access to the system. The attack complexity is HIGH, indicating that successful exploitation may require detailed knowledge of the application's internal structure and data models.
No privileges are required for the attack, and user interaction is not necessary. The confidentiality impact is classified as LOW, meaning that sensitive data may be exposed, although the integrity and availability impacts are assessed as NONE.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-31679 is primarily due to the potential for unauthorized access to sensitive data. Organizations utilizing affected versions of Spring Data REST should assess their exposure and the likelihood of an attacker crafting requests that exploit this vulnerability.
The urgency for organizations to address this issue is categorized as low. Although the exploitability of this vulnerability is low, organizations should still include it in their prioritization for patch cycles, especially if they handle sensitive data that could be compromised.
