CVE-2007-3730
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 · uneditedThe default configuration of the POP server in TCP/IP Services 5.6 for HP OpenVMS 8.3 does not log the source IP address or attempted username for login attempts, which might help remote attackers to avoid identification.
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 POP server in HP OpenVMS TCP/IP Services 5.6 has a default configuration that fails to log the source IP address and attempted usernames for login attempts. This omission weakens security monitoring and incident investigation capabilities by removing key forensic data that would help identify and track remote attackers.

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.
-
Confirm OpenVMS versionRun 'SHOW SYSTEM' or check the OpenVMS version using 'VER /FULL' command to verify the system is running version 8.3Affected if The system is running HP OpenVMS version 8.3 and the POP server is in use
-
Verify POP server is enabledCheck if the POP server service is running. On OpenVMS, this may be checked via 'SHOW SERVICE POP' or reviewing active processes related to POPAffected if POP server service is enabled and running on the system
-
Examine POP server configuration for logging settingsLocate and inspect the POP server configuration file. This is typically found in the TCP/IP services configuration directory. Look for settings related to logging, connection tracking, or audit featuresAffected if Logging is disabled or not configured to capture connection details
-
Check if source IP logging is enabledReview the POP server configuration for directives that control IP address logging. Common settings would include options like 'LOG_IP', 'LOG_ADDRESS', or similar parameters that control whether client source IP addresses are recordedAffected if Source IP address logging is not explicitly enabled in the configuration
-
Check if attempted username logging is enabledReview the POP server configuration for directives that control username logging. Look for settings like 'LOG_USER', 'LOG_AUTH', or similar parameters that control whether attempted usernames are recorded in logsAffected if Username logging for authentication attempts is not explicitly enabled in the configuration
A user is affected if running HP OpenVMS 8.3 with POP server enabled and the default configuration has logging disabled for source IP addresses and attempted usernames.

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 dataEnable comprehensive logging in the POP server configuration to capture source IP addresses and attempted usernames for all login attempts. This is typically done through the POP server's configuration files or management interface.
