CVE-2018-25272
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 · uneditedELBA5 5.8.0 contains a remote code execution vulnerability that allows attackers to obtain database credentials and execute arbitrary commands with SYSTEM level permissions. Attackers can connect to the database using default connector credentials, decrypt the DBA password, and execute commands via the xp_cmdshell stored procedure or add backdoor users to the BEDIENER table.
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 confidenceELBA5 5.8.0 contains an RCE vulnerability where attackers exploit default database connector credentials to connect to the database, decrypt the DBA password, then execute SYSTEM-level commands via the xp_cmdshell stored procedure or create backdoor accounts in the BEDIENER user table.

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 ELBA5 versionLocate the ELBA5 installation directory and check the version information file or application metadata (often found in about dialog, version.txt, or application manifest)Affected if Version is 5.8.0 specifically
-
Verify default database connector credentialsReview database connection configuration files in the ELBA5 installation for hardcoded default credentials; compare against vendor documentation for known default username/password pairsAffected if Default connector credentials (username and password) remain unchanged from vendor defaults
-
Confirm xp_cmdshell stored procedure statusConnect to the underlying SQL Server database and execute: SELECT value_in_use FROM sys.configurations WHERE name = 'xp_cmdshell'; or check via SQL Server Management Studio configuration settingsAffected if xp_cmdshell is enabled (value_in_use = 1)
-
Audit BEDIENER user table for unauthorized accountsConnect to the ELBA5 database and query the BEDIENER table: SELECT * FROM BEDIENER; review all entries for unexpected or unauthorized user accounts created outside normal administrative processesAffected if Table contains user accounts not created by legitimate administrators or accounts with suspicious privileges
A user is affected if running ELBA5 version 5.8.0 with default database credentials still configured, regardless of whether xp_cmdshell is enabled or unauthorized BEDIENER accounts exist
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.
From vendor dataImmediately change default database connector credentials, disable the xp_cmdshell stored procedure if not required for business operations, remediate the password decryption vulnerability in ELBA5, and audit the BEDIENER table for unauthorized accounts.
