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

CVE-2019-13623

Severity High
Score 7.8/10

Summary

In NSA Ghidra before 9.1, path traversal can occur in RestoreTask.java (from the package ghidra.app.plugin.core.archive) via an archive with an executable file that has an initial ../ in its filename. This allows attackers to overwrite arbitrary files in scenarios where an intermediate analysis result is archived for sharing with other persons. To achieve arbitrary code execution, one approach is to overwrite some critical Ghidra modules, e.g., the decompile module.

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.
