CVE-2016-8019

Vulnerability

A cross-site scripting (XSS) vulnerability exists in the attributes handling of the Intel Security VirusScan Enterprise Linux (VSEL) web interface. Versions 2.0.3 and earlier are affected. The flaw is triggered by crafted user input that is not properly sanitized, allowing arbitrary script injection [1].

Exploitation

An unauthenticated remote attacker can exploit this by sending a specially crafted request (e.g., via a URL parameter or form field) containing malicious JavaScript. The input is reflected back in the response without adequate encoding, leading to execution in the victim's browser. No authentication or user interaction is required beyond the victim accessing the crafted link [1].

Impact

Successful exploitation enables arbitrary JavaScript execution in the context of the VSEL web interface. This can lead to session hijacking, defacement, or redirection to malicious sites. The reference notes this XSS can be chained with other vulnerabilities to achieve remote code execution as root, but XSS alone is limited to browser-level attacks [1].

Mitigation

Intel Security has not disclosed a specific fixed version in the available references. Users should upgrade to a patched release if available, or restrict network access to the VSEL web interface as a workaround [1].
