NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in l2tpdconfigshowcgi.c, ipsecshowcgi.c, and modvpnremote/plan.json read handlers. Attackers can query l2tpdconfigshow.cgi to expose stored IPsec PSK and RSA key material.
Netcore NR255-V version 1.5.130703 contains a stored cross-site scripting vulnerability in the DHCP dynamic IP display and ARP bind list display components handling hostname fields. A LAN-based attacker can inject malicious script through these hostname fields, which is later rendered by networkconfig.js and networksecurity.js in the web management interface.
Netcore NR255-V version 1.5.130703 contains an out-of-bounds read vulnerability in filterarpputfile.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.
Netcore NR255-V version 1.5.130703 contains an out-of-bounds read vulnerability in the mtdwrite pre-flash validation routine triggered by short firmware uploads. Attackers can upload a truncated firmware image via putfilecgi.c to trigger out-of-bounds reads across main.c, checkimageuuid.c, and oemMD5Update.c.
Netcore NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in modvpnremote/plan.json, pptpdusershow.cgi, pptpclientconfigshow.cgi, and l2tpdusershow.cgi. Attackers can leverage these components to obtain PPTP and L2TP VPN credentials.
Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in reboottimerset.cgi caused by improper sscanf token parsing. Attackers can exploit this flaw by submitting crafted input to the affected endpoint to corrupt stack memory.
Netcore NR255-V version 1.5.130703 contains a null pointer dereference vulnerability in routepolicyadd.cgi caused by a missing exitport parameter. Attackers can send requests lacking the exitport field to trigger the null pointer dereference, resulting in a denial of service.
Netcore NR255-V firmware version 1.5.130703 contains a stored cross-site scripting vulnerability in routing and NAT configuration CGI components including routingtabaddcgi, routingtablelistshowcgi, routepolicyaddcgi, and routepolicyparameshowcgi. Attackers can inject persistent script payloads through these route and NAT configuration pages, which are then executed in the context of users viewing the affected pages.
Netcore NR255-V version 1.5.130703 contains a null pointer dereference vulnerability in the QoS setter CGI handlers filterconndelcgi.c and grepriosetcgi.c due to unchecked atoi() results. An attacker can trigger the flaw by supplying crafted input to these handlers, causing a denial of service.
Netcore NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in the modqosbandwidth plan.json handling within filterconnsdumpcgi.c and IGDCgiCall.c. Authenticated users with broad roles can access these QoS read routes to obtain live network telemetry beyond their intended privilege level.
NR255-V version 1.5.130703 fails to sanitize QoS rule names before they are parsed via eval() in qosxianzaddcgi, qosxianzshowcgi, qosfilteraddcgi, and qosfiltershowcgi 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.'
Netcore NR255-V version 1.5.130703 contains an os command argument injection vulnerability in the Nettools tcpdump launch paths, including ntoolsstartsetcgi, ntoolstcpdumpstartsetcgi, exedefault, and ntoolsproc components. Attackers can inject crafted arguments into these tcpdump launch routines to manipulate executed system commands on the device.
Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in wakeupset.cgi caused by unbounded tokenization of MAC and ID input. Attackers can supply crafted MAC and ID values to the affected endpoint to overflow the stack buffer and corrupt program memory.
Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in ntoolstcpdumpstartset.cgi caused by an unsized sprintf call when processing form values. An attacker can submit crafted input to this cgi endpoint to overflow the stack buffer and potentially execute arbitrary code.
Netcore NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in the userpassshow.cgi component. Low-privilege attackers can exploit this flaw via uiconfig2.xml and misc.js to disclose router credentials.
Netcore NR255-V version 1.5.130703 contains a stored cross-site scripting vulnerability in ddnswanlistshow.cgi caused by unsafe eval() handling of DDNS data. Attackers can inject malicious script through the DDNS configuration path, leading to persistent execution when the affected page is viewed.
Netcore NR255-V firmware version 1.5.130703 contains a cross-site request forgery vulnerability affecting the wanconfigsetcgi, wannumsetcgi, and lanipchangecgi endpoints. Attackers can craft forged requests to trick authenticated administrators into modifying WAN or LAN network configuration settings without consent.
Netcore NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in the audit endpoints handled by l7webauthlogdumpcgi.c, auditgetcgi.c, and moddispatchauth/plan.json. Attackers can query these audit components to obtain other users' session and browsing history data across sessions.
Netcore NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in l7webauthusershow.cgi related to captive-portal credential handling. Attackers can query this component to obtain captive-portal user credentials, compromising confidentiality of authenticated network access.
