Finding: wavlink-uploadvpn-du-popen-http-20260729
Summary: On July 29, 2026, a fresh multipart POST to /cgi-bin/uploadVpn.cgi?type=wireguard used group='grp2;id>/tmp/cmdproof_0756' and returned HTTP 500, but independent read-back of the live recovery-rootfs file artifacts/rootfs/tmp/cmdproof_0756 immediately after that same request showed uid=0(root) gid=0(root) groups=0(root). This independently confirms root command execution through the du -sh %s popen sink; the HTTP body was not used as the state-change proof. Required screenshots were captured under findings/wavlink-uploadvpn-du-popen-http-20260729/screenshots/, and report.md was written under findings/wavlink-uploadvpn-du-popen-http-20260729/report.md.
