CVE-2015-3943
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 · uneditedAdvantech WebAccess before 8.1 allows remote attackers to read sensitive cleartext information about e-mail project accounts via unspecified vectors.
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 · moderate confidenceAdvantech WebAccess versions prior to 8.1 contain an information disclosure vulnerability where sensitive information about e-mail project accounts is stored or transmitted in cleartext. Remote unauthenticated attackers can read this sensitive data via unspecified vectors.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Identify installed WebAccess versionCheck the WebAccess installation directory or Windows Add/Remove Programs for the version number. Common locations include the installation folder or check the 'About' section in the WebAccess web interface.Affected if The installed version is 8.0 or lower (any version prior to 8.1)
-
Locate email project account configurationSearch the WebAccess installation directory for configuration files related to email settings, project accounts, or notification settings. Common file types include .ini, .xml, .config, or database files.Affected if Configuration files containing email account credentials are found in cleartext (unencrypted)
-
Inspect database storage for credentialsIf WebAccess uses a database (such as SQL Server or Microsoft Access), examine tables that store project or email settings. Check whether password fields are stored as plaintext rather than hashed or encrypted values.Affected if Email account passwords are stored in cleartext within the database
-
Review network traffic for cleartext transmissionUse a network sniffer to capture traffic between the WebAccess client and server when email features are used. Look for SMTP authentication credentials transmitted in plaintext.Affected if SMTP or email credentials are transmitted over the network without encryption (non-SSL/TLS)
The environment is affected if WebAccess version is 8.0 or lower AND email project account credentials are stored or transmitted in cleartext rather than being encrypted.

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 dataUpgrade to Advantech WebAccess version 8.1 or later. If upgrade is not immediately feasible, identify and encrypt/remove any cleartext credential storage and restrict network access to the WebAccess interface.
