CVE-2026-86299: OS Command Injection in Linksys RE7000
CVE-2026-86299 is a critical OS command injection vulnerability in Linksys RE7000 version 2.0.15. It affects the platform_event_pingTest function in the PingTest Handler component, allowing remote attackers to manipulate input parameters to execute arbitrary OS commands. Exploit code is publicly available, increasing the risk of exploitation. No official patch or remediation guidance is currently provided by the vendor.
AI Analysis
Technical Summary
The vulnerability exists in the platform_event_pingTest function of the /cgi-bin/json.cgi?PingTest endpoint in Linksys RE7000 firmware version 2.0.15. Specifically, the arguments pingTestIp, pingTestPktSize, and pingTestTimes can be manipulated to inject OS commands remotely. This flaw allows an unauthenticated attacker to execute arbitrary commands on the device, potentially compromising the system. The CVSS 4.0 base score is 9.4, indicating a critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. Public exploit code is available, but no vendor patch or official fix has been disclosed yet.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected device without authentication. This can lead to full system compromise, unauthorized control, data theft, or disruption of device functionality. The vulnerability is critical due to its remote exploitability and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the device's management interface from untrusted networks and monitor for suspicious activity related to the PingTest functionality. Consider disabling the vulnerable feature if possible.
