CVE-2011-0718
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 · uneditedRed Hat Network (RHN) Satellite Server 5.4 does not use a time delay after a failed login attempt, which makes it easier for remote attackers to conduct brute force password guessing attacks.
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 confidenceRHN Satellite Server 5.4 lacks rate limiting or account lockout mechanisms on its authentication system. After failed login attempts, no time delay is imposed before allowing another attempt, enabling rapid automated password guessing via brute force 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 checksWork through these to decide whether this CVE applies to you.
-
Verify RHN Satellite Server versionCheck the installed version of Red Hat Network Satellite Server (e.g., using 'rhn-schema-version' command, /usr/bin/rhn_check, or querying the database for the server version)Affected if Version is confirmed to be 5.4 (or if the version cannot be determined but the product is RHN Satellite 5.4)
-
Examine account lockout configurationInspect the authentication configuration for account lockout policies. Check PAM configuration files under /etc/pam.d/ related to satellite services, or the RHN Satellite web interface under 'Administration' > 'Users' > 'User Preferences' for lockout settings.Affected if No account lockout policy is configured (e.g., no limit on failed attempts before lockout, or lockout duration is set to 0/disabled)
-
Inspect rate limiting or delay settingsCheck /etc/rhn/rhn.conf or similar RHN configuration files for parameters controlling failed login attempt delays or rate limiting (e.g., 'auth_retries', 'failed_login_delay', or similar options).Affected if No rate limiting or progressive time delay after failed login attempts is configured or enabled
-
Review authentication mechanismExamine the web UI and backend authentication configuration to confirm whether the login mechanism enforces any throttling between failed attempts.Affected if The system allows immediate repeated login attempts without any imposed delay or throttling after authentication failures
The environment is affected if RHN Satellite Server version 5.4 is running and no account lockout policy or login attempt rate limiting/delay mechanism is configured on the authentication system.

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 with configurable thresholds (e.g., lock after 5 failed attempts for 30 minutes) and/or introduce progressive time delays after failed login attempts to slow brute force attacks.
