EUVDB-ID: #VU76427

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-20883

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Specifically, an application is vulnerable if all of the conditions are true:

  • The application has Spring MVC auto-configuration enabled. This is the case by default if Spring MVC is on the classpath.
  • The application makes use of Spring Boot's welcome page support, either static or templated.
  • Your application is deployed behind a proxy which caches 404 responses.
