FAUCET Score

CVE-2017-18372 is a command injection vulnerability affecting Billion 5200W-T TCLinux Fw $7.3.8.0 v008 130603 routers distributed by TrueOnline, as well as some Zyxel products. This high-severity vulnerability (CVSS 8.8) allows an authenticated attacker to execute arbitrary commands through the uiViewSNTPServer parameter on the tools_time.asp page. While authentication is required, it can be bypassed using a separate vulnerability, CVE-2017-18373. Exploit code is publicly available via a Metasploit module, but there is no evidence of active exploitation, nor significant community discussion or media coverage.
