Vulnerability from github – Published: 2022-05-13 01:53 – Updated: 2024-04-25 21:37

Summary

SimpleSAMLphp Use of insecure connection charset (sqlauth module)

Details

The sqlauth module in SimpleSAMLphp before 1.15.2 relies on the MySQL utf8 charset, which truncates queries upon encountering four-byte characters. There might be a scenario in which this allows remote attackers to bypass intended access restrictions.

Severity

9.8 (Critical)

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.
