Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2024-49771

Medium
5.3/10

Summary

MPXJ is an open source library to read and write project plans from a variety of file formats and databases. The patch for the historical vulnerability CVE-2020-35460 in MPXJ is incomplete as there is still a possibility that a malicious path could be constructed which would not be picked up by the original fix and allow files to be written to arbitrary locations. This issue affects the packages mpxj, net.sf.mpxj:mpxj, net.sf.mpxj, net.sf.mpxj-for-csharp, and net.sf.mpxj-for-vb versions 8.3.5 through 13.5.0, and MPXJ.Net versions 13.0.0 through 13.5.0.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
