CVE-2024-28762
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 · uneditedIBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to denial of service with a specially crafted query under certain conditions. IBM X-Force ID: 285246.
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 confidenceIBM Db2 versions 10.5, 11.1, and 11.5 are vulnerable to denial of service when processing a specially crafted query under certain conditions. The vulnerability allows an authenticated attacker to cause the database to become unavailable, likely through resource exhaustion or unexpected query processing behavior.

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 IBM Db2 is installedRun 'db2level' or 'db2pd -versions' to identify the installed Db2 product and componentsAffected if IBM Db2 is returned as the installed database product
-
Determine the installed Db2 versionExecute 'db2level' and parse the version output; look for versions 10.5, 11.1, or 11.5 in the outputAffected if The installed version is exactly 10.5, 11.1, or 11.5
-
Check for authenticated database accessQuery the system catalog table SYSIBMADM.DBAUTH or use 'db2 get authorizations' to review which users have CONNECT or SQLADM authorityAffected if Multiple users or any non-administrative service account has database authentication capability
-
Verify the database accepts SQL queriesConfirm the database is online and accessible by running 'db2 connect to <database>' and executing a simple SELECT queryAffected if The database accepts and processes SQL queries from authenticated connections
-
Review who can execute arbitrary queriesCheck user privileges using 'db2 get authorizations' or query SYSCAT.DBAUTH to identify users with DATAACCESS authority who can run arbitrary queriesAffected if Any user other than the database administrator can execute arbitrary SQL queries
Your environment is affected if IBM Db2 versions 10.5, 11.1, or 11.5 are installed and the database accepts SQL query execution from 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 dataApply the IBM patch for this vulnerability (contact IBM support or consult IBM's security advisories for CVE-2024-28762) and restrict execution of arbitrary queries to trusted, authorized users only.
