Apache Tomcat vulnerability analysis and mitigation
Overview
An Incorrect Default Permissions vulnerability (CVE-2024-46544) was discovered in Apache Tomcat Connectors affecting versions from 1.2.9-beta through 1.2.49. The vulnerability specifically impacts modjk on Unix-like systems, while neither the ISAPI redirector nor modjk on Windows is affected. The issue was disclosed on September 23, 2024, and has been assigned a CVSS v3.1 base score of 5.9 (Medium) (NVD, Apache Security).
