CVE-2024-43373 Information

Description

webcrack is a tool for reverse engineering javascript. An arbitrary file write vulnerability exists in the webcrack module when processing specifically crafted malicious code on Windows systems. This vulnerability is triggered when using the unpack bundles feature in conjunction with the saving feature. If a module name includes a path traversal sequence with Windows path separators an attacker can exploit this to overwrite files on the host system. This vulnerability allows an attacker to write arbitrary .js files to the host system which can be leveraged to hijack legitimate Node.js modules to gain arbitrary code execution. This vulnerability has been patched in version 2.14.1.
