Operationally, ranked in the top 14.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A cross-site scripting vulnerability tracked as CVE-2023-30405 affects the Aigital Wireless-N Repeater Mini_Router running firmware version 0.131229. The flaw is an instance of CWE-79 that permits injection of arbitrary web scripts or HTML through the wl_ssid parameter submitted to the /boafrm/formHomeWlanSetup endpoint.
An authenticated attacker with low privileges can supply a crafted wl_ssid value that is later rendered in the web interface without proper output encoding. Successful exploitation results in script execution in the context of another user's browser session, enabling theft of session tokens or limited interface manipulation, though the CVSS vector requires user interaction and yields only limited confidentiality and integrity impact.
Public references consist solely of PacketStorm disclosures that reproduce the injection vector; no vendor advisory or firmware update addressing the issue is referenced. The associated EPSS score reached a peak of 0.0587 after disclosure before receding to its current value of 0.0259, indicating modest post-publication interest that has since declined.
