CVE-2018-0042
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 · uneditedJuniper Networks CSO versions prior to 4.0.0 may log passwords in log files leading to an information disclosure vulnerability.
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 confidenceJuniper Networks CSO versions prior to 4.0.0 contain an information disclosure vulnerability where user passwords are inadvertently logged in plaintext to log files. An attacker with access to these log files can obtain valid credentials to access the CSO system.

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 CSO versionRun 'show version' or access the CSO admin interface to determine the exact Juniper Contrail Service Orchestration version numberAffected if Version is below 4.0.0
-
Locate CSO log filesAccess the log directory for Juniper CSO, typically found in /var/log/contrail-svc-orchestration or similar service-specific logging pathsAffected if Log files exist and are accessible
-
Search for plaintext passwords in logsUse grep or similar text search to scan log files for patterns matching 'password' or credential-related keywords, examining entries for plaintext password stringsAffected if Log files contain plaintext password strings or credential data in plain text format
-
Verify log file access controlsCheck file permissions on CSO log directories and files to determine if unauthorized users or processes can read themAffected if Log files are readable by users other than the CSO administrator or service account
Affected if CSO version is prior to 4.0.0 and log files contain plaintext password entries accessible to unauthorized users.

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.
dbcve · scoped4.0.0
Upgrade Juniper CSO to version 4.0.0 or later to remediate. Until patched, restrict access to log files and monitor for unauthorized access to log directories.
Contrail Service Orchestration 4.0.0 or later
- Review the Juniper Networks Contrail Service Orchestration upgrade documentation at kb.juniper.net
- Ensure you have a complete backup of your current configuration
- Schedule a maintenance window for the upgrade process
- Upgrade Contrail Service Orchestration to version 4.0.0 or later
- After upgrade, verify that passwords are no longer being logged in log files
- Review post-upgrade log files to confirm the vulnerability is resolved
- Monitor logs going forward to ensure sensitive information is not being recorded
