CVE-2025-14688: CWE-1284 Improper Validation of Specified Quantity in Input in IBM Db2
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.
AI Analysis
Technical Summary
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 for Linux, UNIX, and Windows contain a vulnerability (CWE-1284) related to improper validation of specified quantity in input. This flaw allows an authenticated user to trigger a denial of service by exploiting improper neutralization of special elements in data query logic when certain configurations are present. The CVSS 3.1 base score is 5.3, reflecting a medium severity with network attack vector, high attack complexity, low privileges required, no user interaction, and impact limited to availability.
Potential Impact
An authenticated user can cause a denial of service condition in affected IBM Db2 installations, impacting the availability of the database service. There is no impact on confidentiality or integrity. No known exploits have been reported in the wild to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until an official fix is released, consider restricting authenticated user permissions and reviewing configurations that may expose this vulnerability. Monitor IBM security advisories for updates.
