{"id":"CVE-2026-108894","published":"2026-10-12T14:17:09.897","lastModified":"2026-10-14T18:17:31.883","description":"A security flaw has been discovered in Linksys E1700 1.0.0.4.003. Impacted is the function addStaticRoute of the file /goform/addStaticRoute of the component Static Route Handler. Performing a manipulation of the argument staticRoute_IP_setting/staticRoute_Netmask_setting/staticRoute_Gateway_setting/staticRoute_Metric_setting results in os command injection. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.","cvssScore":9.9,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-77","CWE-78"],"vendors":[],"products":[],"references":[{"url":"https://github.com/wudipjq/my_vuln/blob/main/Linksys3/vuln_68/68.md","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-108894","tags":[]},{"url":"https://vuldb.com/submit/973113","tags":[]},{"url":"https://vuldb.com/vuln/416686","tags":[]},{"url":"https://vuldb.com/vuln/416686/cti","tags":[]},{"url":"https://www.linksys.com/","tags":[]}],"exploitRefs":[{"url":"https://github.com/wudipjq/my_vuln/blob/main/Linksys3/vuln_68/68.md","tags":[]}],"hasPoc":true,"ai":{"summary":"A command injection vulnerability exists in Linksys E1700 routers that allows remote attackers to execute arbitrary OS commands with administrative privileges. This flaw affects the Static Route Handler component and can be exploited by manipulating route settings parameters.","exploitability":"The vulnerability is highly exploitable with no authentication required, allowing remote attackers to inject OS commands through the static route configuration interface with minimal setup.","blast_radius":"The flaw impacts all Linksys E1700 routers running firmware version 1.0.0.4.003, potentially enabling attackers to gain full administrative control over affected devices and use them as entry points for network-wide attacks.","remediation":"Upgrade to firmware version 1.0.0.4.004 or later immediately, as this is the first patch that addresses the command injection vulnerability in the Static Route Handler component.","detection":"Monitor for unusual POST requests to /goform/addStaticRoute endpoint with suspicious command injection patterns in parameters like staticRoute_IP_setting, staticRoute_Netmask_setting, staticRoute_Gateway_setting, or staticRoute_Metric_setting, particularly when these requests originate from unauthenticated sources.","tags":["rce","command-injection","router","network"],"model":"garnet-coder","analyzedAt":"2026-10-13T08:45:42.911Z"}}
