Netcore NR255-V version 1.5.130703 contains an out-of-bounds read vulnerability in filter_arp_put_file.cgi caused by improper use of a string handling API. Attackers can trigger an unterminated buffer over-read by exploiting this flaw in the affected component, potentially exposing adjacent memory contents.
AnalysisAI
An out-of-bounds read in the ARP filter import handler (filter_arp_put_file.cgi) of Netcore NR255-V firmware 1.5.130703 lets an attacker who can reach the router's web management interface and supply a malformed, non-null-terminated string cause the string-handling API to read past the end of an allocated buffer, exposing adjacent process memory in the response. The flaw is rated CVSS 5.3 (CVSS:4.0/AV:N/AC:L/PR:L/UI:N/VC:L/VI:N/VA:L), indicating a network-reachable, low-privilege issue with limited confidentiality and availability impact only — there is no confirmed integrity impact, no CISA KEV listing, and no confirmed public exploit code; the only public material is a VulnCheck advisory plus a third-party GitHub technical reference whose exploit content is unverified.
