CVE-2020-37148: p5 Fnip-4xsh

Low severity, CVSS 3.5. EPSS: 0.3% chance of exploitation in the next 30 days.

P5 FNIP-8x16A/FNIP-4xSH versions 1.0.20 and 1.0.11 suffer from a stored cross-site scripting vulnerability. Input passed to several GET/POST parameters is not properly sanitized before being returned to the user, allowing attackers to execute arbitrary HTML and script code in a user's browser session in the context of the affected site. This can be exploited by submitting crafted input to the label modification functionality, such as the 'lab4' parameter in config.html.

• p5 Fnip-4xsh: version 1.0.20 only; version 1.0.11 only
