CVE-1999-1152
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 · uneditedCompaq/Microcom 6000 Access Integrator does not disconnect a client after a certain number of failed login attempts, which allows remote attackers to guess usernames or passwords 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 confidenceThe Compaq/Microcom 6000 Access Integrator lacks an account lockout mechanism after failed authentication attempts, allowing attackers to perform unlimited brute force attacks to guess valid username/password combinations.

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 Compaq Microcom 6000 deviceInventory network devices or check physical/telnet/console access to locate Compaq Microcom 6000 Access Integrator units in the environmentAffected if The device is present in the environment
-
Check account lockout configurationAccess the device management interface (console, telnet, or admin panel) and navigate to authentication or security policy settings. Look for any setting related to account lockout, account disabling, or failed login limits.Affected if No account lockout policy exists or the setting is absent or disabled
-
Verify brute force protectionAttempt multiple failed authentication attempts (with proper authorization) or review authentication logs to confirm whether the system locks accounts or throttles attempts after a thresholdAffected if The system allows unlimited failed login attempts without triggering any lockout or delay
The environment is affected if a Compaq Microcom 6000 Access Integrator is present and lacks an account lockout mechanism for failed authentication attempts.

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 dataImplement account lockout policies to temporarily disable accounts after a configurable number of failed login attempts, or deploy network-level rate limiting to throttle authentication attempts.
