Short explanation
A vulnerability was found in Netcore NR268 1.7.121109 affecting the eval function of the dhcp_dynamicip_show.cgi file in the DHCP Handler component. Manipulating the Hostname argument results in cross site scripting. The attack may be launched remotely, and a public exploit exists. The vendor did not respond to disclosures, and the patch status is unknown.
This flaw allows remote attacks to be launched, and the existence of a public exploit increases risk. Since the vendor has not responded to disclosures, the patch status remains unknown, requiring security teams to apply alternative safeguards.
What should be done?
- Monitor vendor advisories
- Implement input validation and filtering
- Restrict network access
