CyberRota Analysis

AI-Generated

The IzPack tool for packaging Java applications is vulnerable due to improper handling of file paths in versions 5.2.6 and earlier, allowing attackers to manipulate the installation path and potentially write files outside the intended directory. This vulnerability could lead to unauthorized file creation in sensitive locations, posing a risk of privilege escalation or system compromise. Organizations utilizing IzPack for application deployment should prioritize patching to mitigate this high-severity risk.

Original NVD Description

IzPack is a widely used tool for packaging applications on the Java platform as cross-platform installers. In 5.2.6 and earlier, UnpackerBase.unpack() in izpack-installer/src/main/java/com/izforge/izpack/installer/unpacker/UnpackerBase.java obtains an attacker-controlled PackFile targetPath, passes it through IoHelper.translatePath(), which only converts separators, and constructs a File without normalizing parent-directory segments or enforcing destination containment. A malicious installer pack entry containing ../ sequences can therefore write outside the intended installation directory to startup folders, executable search paths, or other locations accessible with the victim's privileges when the victim runs the installer.
