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
InHand Networks IR615 Router's Versions 2.3.0.r4724 and 2.3.0.r4870 does not enforce an efficient password policy. This may allow an attacker with obtained user credentials to enumerate passwords and impersonate other application users and perform operations on their behalf.

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 confidence

The InHand Networks IR615 Router versions 2.3.0.r4724 and 2.3.0.r4870 fail to enforce a strong password policy, allowing attackers with obtained user credentials to perform password enumeration and impersonate other application users to carry out unauthorized operations.

MitigationUpdate the router firmware to a patched version that enforces strong password complexity requirements and implement account lockout mechanisms to prevent brute-force enumeration attacks.

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 device model and firmware version
    Access the router web interface or check the system status page to locate the device model (IR615) and firmware version information. Alternatively, check the administrative interface or system information page for the exact build version.
    Affected if The firmware version displayed is 2.3.0.r4724 or 2.3.0.r4870 exactly.
  2. Verify password complexity settings
    Navigate to the router administrative interface and locate the user account or password policy configuration section. Look for options related to password complexity, minimum length requirements, character type enforcement, or password strength rules.
    Affected if No password complexity requirements are enforced or the password policy settings are absent, weak, or can be bypassed.
  3. Check account lockout configuration
    In the router administrative interface, locate security or account settings and look for features such as account lockout, failed login attempt limits, or brute-force protection mechanisms.
    Affected if Account lockout mechanisms are missing, disabled, or not configurable, allowing unlimited login attempts.
  4. Test for user enumeration vulnerability
    Attempt to access the login interface with valid usernames but incorrect passwords. Observe whether the system returns different error messages that reveal whether a username exists (for example, 'user does not exist' versus 'incorrect password').
    Affected if The system returns distinct error messages that disclose whether a particular username is valid, enabling enumeration of existing user accounts.
  5. Verify session management and user impersonation controls
    Log into the router with one user account and attempt to access functions or data belonging to a different user account. Check if the system properly validates session tokens or user identity before allowing actions.
    Affected if A user can perform actions or access resources belonging to another user account without proper authorization validation.

You are affected if your IR615 router runs firmware version 2.3.0.r4724 or 2.3.0.r4870 and the system lacks strong password enforcement, account lockout protections, or properly validates user identity to prevent impersonation.
