A cross-site scripting (XSS) vulnerability in Arris NVG443B 9.3.0h3d36 allows attackers to execute arbitrary web scripts or HTML via a crafted POST request sent to /cgi-bin/logs.ha.

do_request in request.c in muhttpd before 1.1.7 allows remote attackers to read arbitrary files by constructing a URL with a single character before a desired path on the filesystem. This occurs because the code skips over the first character when serving files. Arris NVG443, NVG599, NVG589, and NVG510 devices and Arris-derived BGW210 and BGW320 devices are affected.
