CVE-2026-124739
Busybox: httpd stack buffer overflow via an "i:" rule in a subdirectory httpd.conf
Description
A flaw was found in BusyBox. When the httpd web server processes subdirectory configuration files, an overly long index page name can trigger a stack-based buffer overflow. An attacker with permissions to write to a subdirectory configuration file could exploit this vulnerability to execute arbitrary code with elevated privileges or cause a denial of service (DoS) by crashing the server process.
