CVE-2023-30404 is a critical-severity Code Injection (CWE-94) vulnerability in Aigital Wireless-N Repeater Mini Router Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 5.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Aigital Wireless-N Repeater Mini_Router version 0.131229 contains a remote code execution vulnerability in the formSysCmd function, triggered through the sysCmd parameter when processing crafted HTTP requests. The flaw is tracked as CVE-2023-30404 with a CVSS 3.1 score of 9.8 and is associated with CWE-94 code injection weaknesses.
Unauthenticated attackers reachable over the network can submit malicious HTTP requests to execute arbitrary commands on the device. Successful exploitation grants full control of the repeater, enabling confidentiality, integrity, and availability impacts without requiring user interaction or credentials.
The vulnerability was identified through independent hardware testing and disclosed in April 2023, with references including the vendor domain and a detailed technical write-up. The associated EPSS score has remained steady at 0.1465 with no material rise after publication.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
