Vulnerability from github – Published: 2026-04-02 15:31 – Updated: 2026-04-02 15:31

Details

Endian Firewall version 3.3.25 and prior allow authenticated users to delete arbitrary files via directory traversal in the remove ARCHIVE parameter to /cgi-bin/backup.cgi. The remove ARCHIVE parameter value is used to construct a file path without sanitization of directory traversal sequences, which is then passed to an unlink() call.

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.
