VAR-202310-0300

Vulnerability from variot - Updated: 2024-03-04 22:57

Two heap-based buffer overflow vulnerabilities exist in the gwcfg_cgi_set_manage_post_data functionality of Yifan YF325 v1.0_20221108. A specially crafted network request can lead to a heap buffer overflow. An attacker can send a network request to trigger these vulnerabilities.This integer overflow result is used as argument for the malloc function. Yifan YF325 is a wireless router from Yifan Company.

Yifan YF325 has a buffer overflow vulnerability, which originates from a boundary error in the gwcfg_cgi_set_manage_post_data function malloc function when processing untrusted input

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.
