CVE-2025-14688: IBM® Db2® is vulnerable to a denial of service when fetching from certain tables under specific configurations
IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.3 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow an authenticated user to cause a denial of service due to improper neutralization of special elements in data query logic when certain configurations exist.
Security readout for executives and security teams
Plain-English summary
This flaw can let a logged-in user crash or disrupt IBM Db2 under specific configurations when certain table fetches are performed. It does not indicate data theft or data modification, but availability loss could affect systems that depend on Db2.
Executive priority
Treat as a moderate availability risk for business systems using affected Db2 versions. Patch according to IBM guidance, with higher urgency for production databases, shared platforms, or environments where many users can authenticate.
Technical view
CVE-2025-14688 affects IBM Db2 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 for Linux, UNIX, and Windows, including Db2 Connect Server. IBM describes improper neutralization of special elements in data query logic, mapped to CWE-1284, enabling authenticated denial of service.
Likely exposure
Exposure is most likely where affected Db2 or Db2 Connect Server versions are deployed and authenticated users can run queries against affected table/configuration combinations. Internet exposure is not required, but network-reachable database services increase business risk.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and no cited source states active exploitation. The CVSS vector requires low privileges, no user interaction, network access, high attack complexity, and affects availability only.
Researcher notes
The public bundle does not include the exact table conditions, affected configurations, or fixed build identifiers. Analysis should stay anchored to IBM's advisory and avoid assuming exploitability outside authenticated query scenarios.
Mitigation direction
Review IBM advisory 7269424 for the vendor-provided fix or maintenance level.
Prioritize affected Db2 servers supporting critical business applications.
Restrict database access to trusted authenticated users and applications.
Review query privileges for non-administrative users until patched.
Monitor IBM guidance for configuration-specific workarounds or clarifications.
Validation and detection
Inventory Db2 and Db2 Connect Server versions across Linux, UNIX, and Windows hosts.
Compare deployed versions against 11.5.0-11.5.9 and 12.1.0-12.1.3.
Identify systems using configurations referenced by IBM advisory 7269424.
Review service logs for unexplained Db2 interruptions or crashes.
Confirm remediation status against IBM's published advisory.

CWE-1284: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Validation of Specified Quantity in Input
Improper Validation of Specified Quantity in Input represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
