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 · unedited
Siemens SIMATIC WinCC OA before 3.12 P002 January uses a weak hash algorithm for passwords, which makes it easier for remote attackers to obtain access via a brute-force attack.

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 confidence

Siemens SIMATIC WinCC OA versions prior to 3.12 P002 January use a weak hash algorithm for password storage, which allows remote attackers to potentially crack passwords through brute-force attacks and gain unauthorized access to the SCADA system.

MitigationUpgrade to SIMATIC WinCC OA version 3.12 P002 or later which implements stronger password hashing. Until upgraded, enforce network segmentation, restrict access to trusted IP addresses, and monitor for brute-force attempts.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed SIMATIC WinCC OA version
    Check the product version through the WinCC OA manager or look in the installation directory for version information files. Typically found in the installation root or via the 'winccoa -version' command if available in the command line tools.
    Affected if The version displayed is earlier than 3.12 P002 (for example, 3.12, 3.11, 3.10, or any version prior to the January release of 3.12 P002).
  2. Verify password storage configuration
    Locate the user configuration or password storage files within the WinCC OA installation directory. These are typically stored in config or user management directories.
    Affected if Password hashes are stored using a weak or fast hashing algorithm (such as MD5 or SHA1 without proper salting), which makes them vulnerable to brute-force recovery.
  3. Check for default or weak user accounts
    Review the user management system within WinCC OA to identify accounts with default or easily guessable passwords. Examine user configuration files or the user database.
    Affected if Default administrator or operator accounts exist with unchanged passwords, or passwords can be recovered through offline brute-force attacks against the stored hashes.

A user is affected if their installed SIMATIC WinCC OA version is earlier than 3.12 P002 AND the system relies on its built-in password storage for authentication, as passwords would be hashed with a weak algorithm susceptible to brute-force cracking.

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 data
Upgrade available Upgrade to a release after 3.12
Interim mitigation

Upgrade to SIMATIC WinCC OA version 3.12 P002 or later which implements stronger password hashing. Until upgraded, enforce network segmentation, restrict access to trusted IP addresses, and monitor for brute-force attempts.
