CVE-2022-4311
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 · uneditedAn insertion of sensitive information into log file vulnerability exists in PcVue versions 15 through 15.2.2. This could allow a user with access to the log files to discover connection strings of data sources configured for the DbConnect, which could include credentials. Successful exploitation of this vulnerability could allow other users unauthorized access to the underlying data sources.
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 confidencePcVue versions 15 through 15.2.2 write database connection strings (including credentials) to log files when the DbConnect feature is used. Users with access to these log files can discover plaintext credentials and gain unauthorized access to underlying data sources.

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.
-
Check PcVue installed versionLocate the PcVue installation directory and check the version information (typically in about dialog, installer logs, or version file within the program directory)Affected if Installed version is 15.0.0 through 15.2.2 inclusive
-
Identify DbConnect configurationCheck if the DbConnect feature is configured or enabled in the PcVue application (look for database connection configuration files or settings within the Scada environment)Affected if DbConnect feature is actively configured or used for database connections
-
Locate log filesFind the log directory within the PcVue installation or project folder (commonly in logs or data subdirectories)Affected if Log files exist in standard PcVue log locations
-
Inspect logs for plaintext credentialsOpen recent log files and search for patterns containing database connection strings, looking for keywords such as password, connection string, or SQL authentication fields with visible credentialsAffected if Log files contain unredacted database connection strings including username and password fields
User is affected if PcVue version is 15.x through 15.2.2 AND the DbConnect feature is in use AND log files contain plaintext database credentials

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.
dbcve · scopedModify the logging mechanism to either exclude connection strings entirely or mask/redact sensitive credential information before writing to logs. If available, apply vendor patches for version 15.2.3 or later.
PcVue 15.2.3 or later
- 1. Navigate to the official PcVue vendor website at www.pcvuesolutions.com to obtain the latest stable version.
- 2. Download PcVue version 15.2.3 or later, as this version addresses the sensitive information logging vulnerability.
- 3. Before upgrading, backup all existing PcVue project files, configurations, and databases.
- 4. Install the new version following standard PcVue upgrade procedures.
- 5. After installation, verify that log files no longer contain plaintext connection strings or credentials.
- 6. Review DbConnect configuration to ensure credentials are stored securely and not exposed in any logs.
