DescriptionNVD

NETGEAR R8500 1.0.2.158 devices allow remote authenticated users to execute arbitrary commands (such as telnetd) via shell metacharacters in the ipv6_fix.cgi ipv6_wan_ipaddr, ipv6_lan_ipaddr, ipv6_wan_length, or ipv6_lan_length parameter.

AnalysisAI

NETGEAR R8500 1.0.2.158 devices allow remote authenticated users to execute arbitrary commands (such as telnetd) via shell metacharacters in the ipv6_fix.cgi ipv6_wan_ipaddr, ipv6_lan_ipaddr,. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.

Technical ContextAI

This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. NETGEAR R8500 1.0.2.158 devices allow remote authenticated users to execute arbitrary commands (such as telnetd) via shell metacharacters in the ipv6_fix.cgi ipv6_wan_ipaddr, ipv6_lan_ipaddr, ipv6_wan_length, or ipv6_lan_length parameter. Affected products include: Netgear R8500 Firmware.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
