CVE-2022-22970 is a medium-severity vulnerability found in the VMware Spring Framework. This vulnerability allows applications that handle file uploads to be susceptible to denial-of-service (DoS) attacks. The issue arises when these applications rely on data binding to set a MultipartFile or javax.servlet.Part to a field in a model object. With a CVSS score of 5.3, it is crucial for affected organizations to take immediate action.
The vulnerability affects versions of the Spring Framework prior to 5.3.20 and 5.2.22, including older unsupported versions. Given its medium severity, organizations should address this issue in their patch cycle to avoid potential service disruptions.
The exploitation status indicates the possibility of known exploits, making it essential for organizations to prioritize remediation. The attack vector is classified as network-based, which means that an attacker can exploit the vulnerability remotely. Organizations should be aware of the risk associated with this vulnerability and take steps to protect their systems.
Organizations should prioritize patching immediately to mitigate the risks posed by this vulnerability. It is vital to assess the impacted applications and ensure that they are updated to secure versions.
Vulnerability Details
The official CVE description states that in the affected versions of the Spring Framework, applications that handle file uploads are vulnerable to DoS attacks if they rely on data binding to set a MultipartFile or javax.servlet.Part to a field in a model object. The vulnerability has been assigned a CVSS score of 5.3, indicating a medium severity level. The vulnerability impacts the Spring Framework and is classified under CWE-770.
Technical Analysis
The root cause of this vulnerability is linked to how the Spring Framework handles file uploads. Specifically, if applications rely on data binding without proper validation, it can result in a denial-of-service condition. The attack vector is network-based, and the attack complexity is assessed as high, requiring low privileges and no user interaction. The availability impact is high, meaning that successful exploitation could significantly disrupt application services.
Risk & Impact Analysis
Risk to organizations includes potential service outages resulting from successful DoS attacks against applications leveraging the affected Spring Framework versions. The blast radius could encompass multiple services that depend on the framework, increasing the urgency for organizations to implement security updates. Given the CVSS score and the potential for exploitation, organizations should address this in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
