CVE-2022-4312
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 · uneditedA cleartext storage of sensitive information vulnerability exists in PcVue versions 8.10 through 15.2.3. This could allow an unauthorized user with access the email and short messaging service (SMS) accounts configuration files to discover the associated simple mail transfer protocol (SMTP) account credentials and the SIM card PIN code. Successful exploitation of this vulnerability could allow an unauthorized user access to the underlying email account and SIM card.
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 8.10-15.2.3 store SMTP credentials and SIM card PIN codes in cleartext within email and SMS configuration files. An attacker with file system access to these configuration files can read plaintext passwords and PIN codes, enabling unauthorized access to the associated email accounts and SIM cards.

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 versionLocate and read the installed PcVue version information, typically found in the application or its About dialog, installer logs, or program directory metadataAffected if Installed version falls within >= 8.10 and <= 15.2.3
-
Locate email configuration filesSearch the PcVue configuration directories for files related to email or SMTP settings (common names may include email, smtp, mail, or notification in the filename)Affected if Email/SMTP configuration files exist in the PcVue installation directory or configuration folder
-
Locate SMS configuration filesSearch the PcVue configuration directories for files related to SMS or cellular/SIM card settings (common names may include sms, sim, gsm, or cellular in the filename)Affected if SMS configuration files exist in the PcVue installation directory or configuration folder
-
Inspect email config for cleartext passwordsOpen the email/SMTP configuration files and examine whether SMTP usernames, passwords, or server credentials appear as plaintext strings rather than encrypted or masked valuesAffected if SMTP passwords or credentials are stored in cleartext (readable plaintext) within the configuration file
-
Inspect SMS config for cleartext PINsOpen the SMS/cellular configuration files and examine whether SIM card PIN codes or authentication credentials appear as plaintext strings rather than encrypted or masked valuesAffected if SIM card PIN codes are stored in cleartext (readable plaintext) within the configuration file
The environment is affected if PcVue version is between 8.10 and 15.2.3 AND cleartext SMTP passwords or SIM PIN codes are present in email/SMS configuration files accessible to unauthorized users.

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 dataEncrypt sensitive credentials in configuration files using strong encryption (e.g., AES-256) and restrict file system permissions to prevent unauthorized access to configuration files containing sensitive data.
