Zip Slip Vulnerability Exploitation via Zip File Uploads

• •Zip Slip vulnerability allows unauthorized file extraction via zip uploads.
• •The exploit can lead to remote code execution through web shells.
• •Security measures should be implemented to secure file upload functionalities.

A utility script has been released to exploit the Zip Slip vulnerability, which allows attackers to extract files to unintended directories via zip file uploads. This vulnerability can lead to remote code execution by placing malicious web shells in accessible directories. The script generates zip files containing files with '../' in their names, which can be extracted to parent directories, potentially compromising web servers. The default web shell used in the exploit is a PHP shell credited to WhiteWinterWolf. The articles reference resources from Silent Signal Techblog and OWASP, highlighting the risks associated with zip file uploads. The vulnerability has been documented in various GitHub repositories and is a significant concern for web applications that allow file uploads. Security professionals are advised to review their file upload mechanisms to mitigate this risk.
