CVE-2020-37279 Details
Description
easy-pdf-merge 0.1.0 through 0.2.6 contains an OS command injection vulnerability that allows attackers to execute commands by injecting shell metacharacters into source paths, destination path, or maxHeap option. Attackers can supply file names or options containing double quotes, semicolons, $() or backticks, which child_process.exec() runs through a shell with the Node.js process privileges.
A command injection vulnerability has been identified in the easy-pdf-merge npm module, specifically in versions 0.1.0 through 0.2.6. This vulnerability allows attackers to execute arbitrary commands by injecting shell metacharacters into the source file paths, destination path, or the maxHeap option. The injected commands are executed by child_process.exec() with the privileges of the Node.js process, potentially leading to unauthorized command execution on the server.
Users can update to version 0.2.6 or later, where this vulnerability has been fixed. The patched version is available on the npm registry.
