CVE-2026-63586Unauthenticated Remote Code Execution via Shell Injection in Web Management Interface
Critical 9.8
In plain English
A critical-severity OS command injection in IE-SR-2TX-WL from Weidmueller Interface. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.9% (higher than 61% of all known vulnerabilities).
Official description
The web-based management interface uses a modified uhttpd server with CGI shell scripts. The HTTP Basic Authentication username, taken directly from the Authorization header without sanitization, is inserted into a shell command string executed via the system() function. By submitting a specially crafted username containing shell metacharacters, an unauthenticated attacker with network access to the device can escape the command context and execute arbitrary commands with root privileges.
