CVE-2019-4321
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 · uneditedIBM Intelligent Operations Center V5.1.0 - V5.2.0, IBM Intelligent Operations Center for Emergency Management V5.1.0 - V5.1.0.6, and IBM Water Operations for Waternamics V5.1.0 - V5.2.1.1 does not require that users should have strong passwords by default, which makes it easier for attackers to compromise user accounts. IBM X-Force ID: 161201.
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 confidenceThe affected IBM products (Intelligent Operations Center, Intelligent Operations Center for Emergency Management, and Water Operations for Waternamics) do not enforce strong password policies by default, allowing weak passwords that are susceptible to brute-force or dictionary attacks.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 product and versionLocate the product version information in the IBM Intelligent Operations Center installation or admin consoleAffected if The installed version falls outside the affected ranges (Intelligent Operations Center 5.1.0-5.2.0, Intelligent Operations Center for Emergency Management 5.1.0-5.1.0.6, Water Operations for Waternamics 5.1.0-5.2.1.1)
-
Confirm product is in affected rangeCompare your installed version against the affected version ranges listed for your specific productAffected if Version is within any of these ranges: IOC 5.1.0-5.2.0, IOC for EM 5.1.0-5.1.0.6, or Water Ops 5.1.0-5.2.1.1
-
Check password policy configurationAccess the system security or user management settings where password policies are definedAffected if Password policy is set to default or allows weak passwords without enforced complexity requirements
-
Verify password complexity requirementsInspect the password policy for minimum length, character complexity rules, and whether these are actively enforcedAffected if Minimum password length is short (e.g., under 8 characters) or no complexity requirements (uppercase, lowercase, numbers, special characters) are enforced
-
Check account lockout and brute-force protectionsLook for account lockout thresholds and failed login attempt protections in security settingsAffected if No account lockout after failed attempts or no brute-force protection mechanisms are configured
Your environment is affected if the product version falls within the affected ranges AND password policies are set to default without enforced strong password requirements such as minimum length, complexity, and account lockout thresholds.

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 dataConfigure and enforce strong password policies including minimum length, complexity requirements, password expiration, and account lockout thresholds.
