CVE-2026-76864 Details
Description
NR255-V version 1.5.130703 fails to sanitize QoS rule names before they are parsed via eval() in qos_xianz_add_cgi, qos_xianz_show_cgi, qos_filter_add_cgi, and qos_filter_show_cgi handlers. An attacker can inject persistent script code through crafted QoS rule name input that executes when the stored data is later processed by the affected handlers.'
A stored cross-site scripting vulnerability has been identified in Netcore NR255-V version 1.5.130703. The issue arises because QoS rule names are not properly sanitized before being processed by several handlers, including qos_xianz_add_cgi, qos_xianz_show_cgi, qos_filter_add_cgi, and qos_filter_show_cgi. This lack of sanitation allows attackers to inject persistent script code through manipulated QoS rule names, which is executed when the data is later accessed by the affected handlers.
