CVE-2024-42831

Vulnerability

Description CVE-2024-42831 is a reflected cross-site scripting (XSS) vulnerability in Elaine's Realtime CRM Automation version 6.18.17. The flaw exists in the wrapper_dialog.php script, where the dialog parameter is not properly sanitized before being reflected back to the user. This allows an attacker to inject arbitrary JavaScript code into the web page.

Exploitation

To exploit this vulnerability, an attacker must craft a malicious URL containing a payload in the dialog parameter and trick a victim into clicking it. No authentication is required to access the vulnerable script, making the attack surface broad. The payload executes in the context of the victim's browser session.

Impact

Successful exploitation enables the attacker to execute arbitrary JavaScript in the victim's browser. This can lead to session hijacking, theft of sensitive data, defacement of the application, or other malicious actions that rely on the victim's session.

Mitigation

As of the publication date, no official patch or workaround has been released. Affected users should consider implementing input validation on the dialog parameter, using a web application firewall (WAF) to block malicious payloads, or restricting access to wrapper_dialog.php until a fix is available.
