CVE-2026-112371: H3C Magic NX15 code injection in /api/esps RPC interface

CVE-2026-112371 · Severity: critical · CVSS 9.9 · Published 2026-10-19

The H3C Magic NX15 router contains a code injection vulnerability in its RPC interface that allows authenticated attackers to achieve remote code execution as root. By manipulating the path argument in the file write function, an attacker can overwrite system plugins and inject arbitrary commands. This gives an attacker complete control over the router, enabling data theft, network manipulation, or deployment of malware.

Technologies: H3C Magic NX15. Vendors: H3C.

Technical details

The /api/esps RPC interface's write method performs no path validation, allowing authenticated users to overwrite arbitrary files in /usr/libexec/rpcd/. By overwriting plugin scripts executed by the rpcd daemon with root privileges, attackers can inject shell commands that execute as root. The vulnerability requires valid credentials but no additional user interaction, and affects NX15V100R017.
