CVE-2018-16134

Vulnerability

Cybrotech CyBroHttpServer version 1.0.3 does not sanitize user-supplied input in the URI, allowing an attacker to inject arbitrary HTML and JavaScript. The vulnerability is triggered when the server processes a request containing a `` and tricking a victim into opening it. No authentication or special network position is required; the victim only needs to visit the malicious link. The server reflects the injected script in the response, causing it to execute in the victim's browser [1][2].

Impact

Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of the victim's browser session. This can lead to information disclosure, session hijacking, or further attacks against the user. The impact is limited to the client side, but the attacker can potentially steal cookies, credentials, or perform actions on behalf of the victim [1][2].

Mitigation

As of the publication date (2018-08-29), no official patch or updated version has been released by Cybrotech. Users are advised to avoid clicking untrusted links and to consider using a web application firewall (WAF) to filter malicious requests. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog [1][2].
