In Spring Security, versions 5.7.x prior to 5.7.12, 5.8.x prior to 5.8.11, versions 6.0.x prior to 6.0.9, versions 6.1.x prior to 6.1.8, and versions 6.2.x prior to 6.2.3, an application is possible vulnerable to broken access control when it directly uses the AuthenticatedVoter#vote passing a null Authentication parameter. This vulnerability is classified as high severity with a CVSS score of 8.2.
Risk to organizations includes potential unauthorized access to sensitive resources due to improper authentication handling. Inadequate controls may lead to exploitation opportunities, where attackers can bypass security measures.
Given the high severity of this vulnerability, organizations should prioritize patching immediately. The lack of known exploits or public proof of concept (PoC) does not reduce the urgency for remediation, as the potential for exploitation remains.
This situation emphasizes the importance of maintaining up-to-date security practices and ensuring that all components are monitored for vulnerabilities.
Organizations using affected versions of Spring Security should take immediate action to update to the latest versions as specified by the vendor.
The vulnerability was published on March 18, 2024, and remains under analysis.
Vulnerability Details
The CVE-2024-22257 vulnerability allows for broken access control due to the direct use of the AuthenticatedVoter#vote method with a null Authentication parameter. This could lead to unauthorized access to sensitive data. The vulnerability is classified under CWE-862, indicating issues related to access control.
The CVSS score of 8.2 indicates a high level of severity. The vulnerability could be exploited over a network with a low attack complexity, requiring no privileges or user interaction. The confidentiality impact is high, while the integrity impact is low, and availability impact is none.
Technical Analysis
The root cause of this vulnerability stems from a failure to properly validate the Authentication parameter in the AuthenticatedVoter#vote method. Applications that rely on this method without sufficient checks may inadvertently allow unauthorized access.
The attack vector is network-based, allowing attackers to exploit this vulnerability remotely. The attack complexity is low, and the execution does not require any privileges or user interactions. The vulnerability significantly affects confidentiality, as unauthorized users may gain access to restricted resources.
Risk & Impact Analysis
Organizations utilizing Spring Security must recognize the real-world risk associated with this vulnerability. The potential for unauthorized access to sensitive data poses a significant threat to data integrity and confidentiality.
The blast radius for this vulnerability could extend across various applications relying on the affected versions of Spring Security, amplifying the urgency to address this flaw through timely patching.
Given the CVSS score of 8.2 and the potential impact on confidentiality, organizations should prioritize remediation efforts within their security patch cycles.
