It has a critical information disclosure vulnerability. An unauthenticated attacker can send properly formatted requests to the web application and download sensitive files and information. For example, the /DATAREPORTS directory can be farmed for reports. Because this directory contains the results of reports such as NMAP, Patch Status, and Active Directory domain metadata, an attacker can easily collect this critical information and parse it for information. There are a number of directories affected.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-306"],"references":["http://dfdrconsulting.com/2019/cyber-security/cve-2019-15506-kaseya-vsa-critical-information-disclosure-unauthenticated-access/","http://help.kaseya.com/WebHelp/EN/RN/index.asp#VSAReleaseNotes.htm","http://dfdrconsulting.com/2019/cyber-security/cve-2019-15506-kaseya-vsa-critical-information-disclosure-unauthenticated-access/","http://help.kaseya.com/WebHelp/EN/RN/index.asp#VSAReleaseNotes.htm"],"products":["kaseya:virtual_system_administrator"],"source":"nvd","synced_at":"2026-10-19T20:58:39.700375520+00:00"},"epss":{"cve":"CVE-2019-15506","score":0.01811,"percentile":0.7863,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
