Status: DeferredHigh (8.6)—
Severity8.6High · CVSS 4.0
Exploitation probability2.16 %higher than 82% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

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.
