What is CVE-2024-53677?
CVE-2024-53677 is a critical vulnerability in Apache Struts, published on 11 Dec 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
File upload logic in Apache Struts is flawed. An attacker can manipulate file upload params to enable paths traversal and under some circumstances this can lead to uploading a malicious file which can be used to perform Remote Code Execution.
This issue affects Apache Struts: from 2.0.0 before 6.4.0.
Users are recommended to upgrade to version 6.4.0 at least and migrate to the new file upload mechanism https://struts.apache.org/core-developers/file-upload . If you are not using an old file upload logic based on FileuploadInterceptor your application is safe.
