GHSA-R6RH-C775-H225

Vulnerability from github – Published: 2025-05-12 21:31 – Updated: 2025-05-12 21:31

Details

Improper authentication handling was identified in a set of HTTP POST requests affecting the following product families:

Digi PortServer TS - prior to and including 82000747_AA, build date 06/17/2022
Digi One SP/Digi One SP IA/Digi One IA - prior to and including 82000774_Z, build date 10/19/2020
Digi One IAP – prior to and including 82000770 Z, build date 10/19/2020

A specially crafted POST request to the device’s web interface may allow an unauthenticated attacker to modify configuration settings.

Severity

9.4 (Critical)


                  
                    CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L

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.
