Title
Authenticated SQLi in UpdateParam function
Summary
A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the admin.mbnetj.php files UpdateParam function due to improper neutralization of special elements in a SQL UPDATE command allowing for reading the whole database and changing values in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.

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.
