Vulnerability from github – Published: 2026-09-15 21:31 – Updated: 2026-09-15 21:31

Details

A vulnerability exists in the configuration processing logic of the affected component where malformed input is improperly processed. An authenticated remote attacker with administrative privileges could exploit this vulnerability by providing specially crafted configuration data. Successful exploitation could result in a stack-based buffer overflow, potentially leading to remote code execution with root privileges or a denial of service due to a system crash.

Severity

7.2 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

Detection rules are retrieved from Rulezet.

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.
