Description:

CVE-2024-38816 is a path traversal vulnerability in Spring Framework, a popular Java web framework. It allows attackers to access files on the server's file system, potentially leading to sensitive data exposure or remote code execution. The SVRS of 38 indicates a moderate risk, requiring attention and timely mitigation.

Key Insights:

• Exploitable in Specific Configurations: The vulnerability is only exploitable when the application uses RouterFunctions to serve static resources and explicitly configures resource handling with a FileSystemResource location.
• File System Access: Attackers can access any file on the file system that is accessible to the Spring application process, including sensitive data such as passwords or configuration files.
• Active Exploits: Active exploits have been published, indicating that attackers are actively exploiting the vulnerability.

Mitigation Strategies:

• Update Spring Framework: Upgrade to Spring Framework version 6.0.5 or later, which includes a fix for this vulnerability.
• Use Spring Security HTTP Firewall: Enable the Spring Security HTTP Firewall to block malicious requests.
• Run on Tomcat or Jetty: Deploy the application on Tomcat or Jetty, which provide built-in protection against path traversal attacks.
• Restrict File Access: Limit the application's access to only the necessary files and directories on the file system.

Additional Information:

• The Cybersecurity and Infrastructure Security Agency (CISA) has warned of the vulnerability, calling for immediate and necessary measures.
• The vulnerability is actively exploited by hackers in the wild.
• If users have additional queries regarding this incident, they can use the 'Ask to Analyst' feature, contact SOCRadar directly, or open a support ticket for more information if necessary.
