CVE-2017-16015 : What You Need to Know

Forms is a software toolkit that allows for the effortless generation of HTML forms. In earlier iterations of the library (prior to 1.3.0), appropriate measures for HTML escape were not implemented. Consequently, in cases where the application failed to sanitize HTML content submitted through forms, the utilization of forms could potentially expose vulnerabilities, such as cross-site scripting.

Understanding CVE-2017-16015

Forms library versions before 1.3.0 were susceptible to cross-site scripting due to improper HTML escaping.

What is CVE-2017-16015?

CVE-2017-16015 is a vulnerability in the Forms node module by HackerOne, allowing for potential cross-site scripting attacks.

The Impact of CVE-2017-16015

The vulnerability could lead to cross-site scripting attacks if HTML content submitted through forms was not properly sanitized.

Technical Details of CVE-2017-16015

Forms library versions prior to 1.3.0 lacked proper HTML escaping, exposing applications to cross-site scripting.

Vulnerability Description

The vulnerability stems from inadequate HTML escaping in Forms library versions before 1.3.0, enabling cross-site scripting attacks.

Affected Systems and Versions

Product: Forms node module
Vendor: HackerOne
Versions Affected: <1.3.0

Exploitation Mechanism
