CVE-2020-7836
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVOICEYE WSActiveBridgeES versions prior to 2.1.0.3 contains a stack-based buffer overflow vulnerability caused by improper bound checking parameter given by attack. It finally leads to a stack-based buffer overflow via access to crafted web page.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceVOICEYE WSActiveBridgeES versions before 2.1.0.3 contain a stack-based buffer overflow vulnerability due to improper bounds checking on parameters passed through a crafted web page. The lack of input validation allows an attacker to overflow a stack-allocated buffer by supplying specially crafted data via the web interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm VOICEYE WSActiveBridgeES installationLocate the application on the system by searching for WSActiveBridgeES-related files, services, or installed components. Check installed programs list or application directories.Affected if The software is present on the system
-
Identify installed versionCheck the application version through its built-in about dialog, version information in executable properties, or configuration files. Look for version markers in the WSActiveBridgeES installation directory.Affected if The installed version is any version before 2.1.0.3
-
Verify web interface is accessibleDetermine if the web interface component is enabled and reachable by checking the service status, listening network ports (typically HTTP/HTTPS), or attempting to access the web portal URL.Affected if The web interface is exposed and the installed version is below 2.1.0.3
-
Review web service configurationExamine the WSActiveBridgeES configuration files or service settings to confirm the web component is active, as the buffer overflow is triggered through the web interface.Affected if The web service is enabled and the version is vulnerable
A user is affected if VOICEYE WSActiveBridgeES is installed with the web interface enabled and the version is below 2.1.0.3.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data2.1.0.3
Update VOICEYE WSActiveBridgeES to version 2.1.0.3 or later to obtain the patched version with proper parameter bound checking. If immediate patching is not possible, restrict web access to the affected component and implement input validation at a perimeter layer.
