CVE-2026-31195: n/a
OS command injection vulnerability in the ping diagnostic handler in /bin/httpd_clientside in ALTICE LABS / SFR France GR140DG Fibre Router with firmware 3GN8020801R13, 3GN8020802R0A, or 3GN8020803R0A inserts unsanitized user input into a system() call, allowing authenticated remote attackers to execute arbitrary commands as root via crafted destAddr parameters using shell command substitution.
AI Analysis
Technical Summary
CVE-2026-31195 describes an OS command injection vulnerability in the ping diagnostic handler located in /bin/httpd_clientside on ALTICE LABS / SFR France GR140DG Fibre Router devices running firmware versions 3GN8020801R13, 3GN8020802R0A, or 3GN8020803R0A. The vulnerability arises because user-supplied input in the destAddr parameter is not properly sanitized before being used in a system() call, enabling authenticated remote attackers to execute arbitrary commands with root privileges via shell command substitution.
Potential Impact
Successful exploitation allows an authenticated remote attacker to execute arbitrary commands as root on the affected router, potentially leading to full device compromise, disruption of service, and unauthorized control over network traffic.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, restrict access to the router's management interface to trusted users only and monitor for suspicious activity. Avoid exposing the diagnostic functionality to untrusted networks.
