CVE-2013-2045
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 · uneditedSQL injection vulnerability in lib/db.php in ownCloud Server 5.0.x before 5.0.6 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.
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 confidenceSQL injection vulnerability in lib/db.php in ownCloud Server 5.0.x before 5.0.6 allows remote authenticated users to execute arbitrary SQL commands. The vulnerability stems from unsanitized user input being passed to database queries, enabling attackers with valid credentials to manipulate SQL statements.

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 versionAccess the ownCloud admin panel and navigate to the version information page, or check the version file in the ownCloud installation directory if accessibleAffected if The installed version is 5.0.0, 5.0.1, 5.0.2, 5.0.3, 5.0.4, or 5.0.5 (any version 5.0.x before 5.0.6)
-
Confirm the vulnerable file lib/db.php existsLocate and verify the presence of lib/db.php in the ownCloud installation directoryAffected if The file lib/db.php exists in the ownCloud installation and the version is in the affected range
-
Verify remote network access to ownCloudDetermine whether the ownCloud instance is accessible over the network (not localhost-only) by checking network configuration and firewall rulesAffected if The ownCloud server is reachable from remote network locations, allowing external attackers to potentially authenticate and exploit the SQL injection
-
Review user authentication configurationCheck the ownCloud authentication settings to confirm that user accounts can be created or accessed remotelyAffected if Remote user authentication is enabled, allowing attackers to obtain valid credentials to exploit the SQL injection
-
Check database user privilegesReview the database user configuration used by ownCloud to determine if the application database user has excessive privilegesAffected if The ownCloud database user has privileges beyond what is minimally required, which could allow SQL injection to have broader impact
A user is affected if their ownCloud Server installation is version 5.0.0 through 5.0.5 and is accessible to remote authenticated 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.
From vendor dataUpgrade ownCloud Server to version 5.0.6 or later to receive the patch for this SQL injection vulnerability. If immediate upgrade is not feasible, restrict network access to the ownCloud instance and review authentication controls.
