Multiple reflected cross-site scripting (XSS) vulnerabilities in the login.php endpoint of Interzen Consulting S.r.l ZenShare Suite v17.0 allows attackers to execute arbitrary Javascript in the context of the user's browser via a crafted URL injected into the codice_azienda and red_url parameters.
AnalysisAI
Reflected cross-site scripting (XSS) vulnerabilities in Interzen Consulting ZenShare Suite v17.0 login.php endpoint allow remote unauthenticated attackers to execute arbitrary JavaScript in a user's browser by injecting malicious payloads into the codice_azienda and red_url parameters. Attack requires user interaction (clicking a crafted link) and affects the authentication process; no public exploit code or active exploitation has been confirmed at time of analysis.
Technical ContextAI
The vulnerability exists in a PHP-based web application (login.php endpoint) where user-supplied input from URL parameters (codice_azienda and red_url) is reflected in HTTP responses without proper sanitization or encoding. This is a classic reflected XSS attack vector where an attacker crafts a malicious URL containing JavaScript payloads that execute in the victim's browser within the security context of the ZenShare Suite application, potentially allowing session hijacking, credential theft, or malware injection. The vulnerability affects Interzen Consulting S.r.l's ZenShare Suite product line, though specific CPE strings and detailed version boundaries are not fully populated in the available data.
RemediationAI
Contact Interzen Consulting S.r.l for a patched version of ZenShare Suite addressing the reflected XSS in login.php. Until a vendor patch is released, implement input validation and output encoding on the codice_azienda and red_url parameters: validate input against a whitelist of expected characters, reject or sanitize any HTML/JavaScript metacharacters, and apply HTML entity encoding to all reflected output. Deploy Web Application Firewall (WAF) rules to detect and block reflected XSS payloads targeting these parameters. Review application logs for evidence of exploitation attempts.
