CVE-2018-13104

Vulnerability

OX App Suite versions 7.8.4 and earlier contain a cross-site scripting (XSS) vulnerability. The bug, tracked internally as 58742, allows an attacker to inject arbitrary JavaScript into the application through unsanitized user input. The vulnerability exists in the web interface and does not require any special configuration beyond default settings.

Exploitation

An attacker can exploit this vulnerability by crafting a malicious payload and submitting it via a form or other input field that is not properly sanitized. The payload is then stored and executed in the context of the victim's browser when the victim views the affected page. No authentication is required if the vulnerable input is publicly accessible; otherwise, the attacker may need a valid account with permission to submit content.

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the victim's browser. This can lead to session hijacking, theft of sensitive data (e.g., cookies, tokens), defacement, or redirection to malicious sites. The attack operates within the security context of the OX App Suite domain, potentially compromising all data accessible through the victim's session.

Mitigation

As of the publication date (2019-03-17), no patch is mentioned in the available references. Users should upgrade to a version later than 7.8.4 if a fix has been released by the vendor. If no update is available, administrators should implement web application firewall rules to filter XSS payloads and enforce strict input validation.
