Vulnerability categories we encourage

We treat all reports with high priority and investigate all issues directly with the reporter as quickly as possible. Please when you make a report, do so in English via security@eset.com and include the following information:

Target – ESET server identified by IP address, hostname, URL and so forth or the ESET product, including version number (see our KnowledgeBase article to determine the version number)
Type of issue – the type of vulnerability (e.g. according to OWASP, such as cross-site scripting, buffer overflow, SQL injection, etc.) and include a general description of the vulnerability.
Proof-of-concept and/or URL demonstrating the vulnerability – a demonstration of the vulnerability that shows how it works. Examples include:
● URL containing payload – e.g. XSS in GET request parameters
● Link to general checker – e.g. SSL vulnerabilities
● Video – generally useable (if uploading to a streaming service, please mark it as private)
● Log file from ESET SysInspector (see how to create ESET SysInspector log) or Microsoft Problem Steps Recorder (see how to use Problem Steps Recorder), if applicable
● Please provide as detailed description as you can, or send us a combination of any of the previous choices.
