Upstream source description

Netcore NR256CN through 1.5.140116 contains an unauthenticated file write vulnerability in the Boa-derived /bin/boa web server that allows remote attackers to overwrite update and restore staging files. Attackers can POST to a non-existent .cgi pathname to write attacker-controlled content into /tmp/boa_temp.update or /tmp/boa_temp.para, tampering with pending firmware updates or configuration restores or causing denial of service.
