PeaZip versions before 11.3.0, when used in a non-default configuration, are vulnerable to OS command injection through specially crafted filenames in archives. This occurs due to improper handling of quotation characters in the filename string. The vulnerability allows an attacker to execute arbitrary OS commands with limited attack complexity but requires user interaction. No official patch information is provided in the input data.
AI Analysis
Technical Summary
The vulnerability in PeaZip before version 11.3.0 arises from mishandling of quotation characters in archive filenames when the software is configured in a non-default manner. This flaw enables OS command injection, potentially allowing an attacker to execute arbitrary commands on the host system. The CVSS 4.0 vector indicates local attack vector, low attack complexity, partial user interaction, and high impact on confidentiality, integrity, and availability. No vendor advisory or patch details are provided in the source data.
Potential Impact
Successful exploitation can lead to arbitrary OS command execution with high impact on confidentiality, integrity, and availability of the affected system. The attack requires local access and some user interaction, limiting remote exploitation. There is no information about active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using non-default configurations that process untrusted archive filenames or limit the use of PeaZip to trusted archives only.
