VAR-201609-0432
Vulnerability from variot - Updated: 2025-04-13 23:27The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow. ESnetiPerf3 is a suite of tools for testing the maximum bandwidth in an IP network. A heap buffer overflow vulnerability exists in the JSON processing function of Esnetiperf version 3.1.1. ESnet iPerf3 is prone to a heap-based buffer-overflow vulnerability. Failed attempts will likely cause a denial-of-service condition. ESnet iPerf3 3.1.1. and 3.1-1 are vulnerable; other versions may also be affected

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.
