Vulnerability from github – Published: 2023-03-30 15:30 – Updated: 2023-04-06 18:30

Details

A buffer overflow vulnerability exists in the handling of wildcard backend hosts of SNIProxy 0.6.0-2 and the master branch (commit: 822bb80df9b7b345cc9eba55df74a07b498819ba). A specially crafted HTTP, TLS or DTLS packet can lead to arbitrary code execution. An attacker could send a malicious packet to trigger this vulnerability.

Severity

9.8 (Critical)

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.
