Hello,
I can confirm the same bug on a CAP700 (ALTOS), firmware CAP7_R_00.07.24 — uhttpd dies with a segmentation fault on every CLI session continuation request (session creation itself succeeds), which the browser reports as “Session closed”. So the issue is not RUTX-specific. Full diagnosis with a deterministic curl reproducer and crash signature here: CAP700 (ALTOS) WebUI CLI "Session closed"-uhttpd segfault on session continuation (same bug as RUTX50 CLI Broken)
