Vulnerability from github – Published: 2026-04-27 18:32 – Updated: 2026-04-27 18:32

Details

ProjeQtor versions 7.0 through 12.4.3 contain a ZipSlip path traversal vulnerability in the plugin upload functionality that allows authenticated attackers with upload permissions to write files outside the intended extraction directory by crafting ZIP archives with directory traversal sequences. Attackers can exploit unvalidated archive extraction to write a PHP webshell to a web-accessible directory and achieve remote code execution with the privileges of the web server process.

Severity

8.8 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
