CVE-2014-2048
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 user_openid app in ownCloud Server before 5.0.15 allows remote attackers to obtain access by leveraging an insecure OpenID implementation.
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 confidenceThe user_openid app in ownCloud Server versions prior to 5.0.15 contains an insecure OpenID implementation that allows remote attackers to obtain unauthorized access to the ownCloud instance. The vulnerability stems from improper validation or handling of OpenID authentication requests, enabling authentication bypass.

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 the installed ownCloud Server versionLocate the ownCloud version via the admin dashboard under Admin > General, or check the version.php file in the ownCloud root directory or config/version.xml fileAffected if The installed version is any release prior to 5.0.15 (e.g., 5.0.14, 5.0.10, 4.x)
-
Verify if the user_openid app is presentNavigate to the ownCloud Apps panel and check if the user_openid app is listed as installed, or inspect the apps/user_openid directory within the ownCloud installation folderAffected if The user_openid app is installed and enabled on the server
-
Confirm OpenID authentication is in useReview the ownCloud authentication settings in the admin panel or check the config/config.php file for openid-related configuration parametersAffected if OpenID authentication is enabled or configured as an authentication method
You are affected if your ownCloud Server version is below 5.0.15 AND the user_openid app is installed and enabled, as this combination allows the authentication bypass vulnerability to be exploited.
Generated from the published advisory. Verify against your own configuration.
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 · scoped5.0.15
Upgrade ownCloud Server to version 5.0.15 or later to patch the insecure OpenID implementation. If the user_openid app is not required, disable or remove it as an immediate workaround.
ownCloud Server 5.0.15
