CVE-2023-52948
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 · uneditedMissing encryption of sensitive data vulnerability in settings functionality in Synology Active Backup for Business Agent before 2.7.0-3221 allows local users to obtain user credential 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 confidenceSynology Active Backup for Business Agent versions prior to 2.7.0-3221 store user credentials in the settings functionality without encryption, allowing local users with access to the system to read sensitive authentication data via unspecified vectors.

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 agent versionOpen Synology Active Backup for Business Agent and navigate to Help > About, or check the installed programs list in Windows Control Panel. Locate the version number displayed.Affected if The version number is lower than 2.7.0-3221
-
Confirm credentials are configured in the agentAccess the Synology Active Backup for Business Agent settings or configuration interface. Check whether backup jobs, storage connections, or authentication credentials have been configured and saved.Affected if User credentials for backup destinations or authentication have been stored in the agent configuration
-
Locate settings storage for plaintext credentialsInspect the local application data directory where Synology Active Backup for Business Agent stores configuration files. Common paths include %ProgramData%\Synology\ActiveBackupForBusinessAgent or similar user-specific AppData locations. Search configuration XML or JSON files for unencrypted username and password fields.Affected if Plaintext username and password values are present in configuration files or settings storage, rather than encrypted or hashed representations
Your environment is affected if the installed Synology Active Backup for Business Agent version is prior to 2.7.0-3221 and you have configured credentials within the agent, which are then stored in plaintext in local configuration files.
Generated from the published advisory. Verify against your own configuration.
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.
