Summary

The Sangfor Next-Gen Application Firewall version NGAF8.0.17 is vulnerable to an operating system command injection vulnerability. A remote and unauthenticated attacker can execute arbitrary commands by sending a crafted HTTP POST request to the /cgi-bin/login.cgi endpoint. This is due to mishandling of shell meta-characters in the PHPSESSID cookie.

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.
