Technical Analysis

This vulnerability exists in H3C NX15 V100R017 within the reload.reload_config function of the /api/esps file. It allows remote command injection, enabling an attacker to execute arbitrary commands on the device. The vulnerability has a CVSS 4.0 base score of 8.6, indicating high severity.
