Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Privilege escalation via a crafted query realistically requires an existing low-privileged database session, so PR:L rather than PR:N; network vector, low complexity, and full C/I/A impact once escalated.

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.5 is vulnerable to privilege escalation with a specially crafted query.
AnalysisAI
Privilege escalation in IBM Db2 (data server versions 11.5.0-11.5.9 and 12.1.0-12.1.5) allows an attacker to submit a specially crafted query that bypasses authorization controls and gains elevated database privileges, classified as CWE-285 improper authorization. IBM reported the issue and has published a fix; there is no public exploit identified at time of analysis and it is not on CISA KEV. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The exploitation trigger is a single specific action: submitting a specially crafted SQL query to an affected Db2 instance (11.5.0-11.5.9 or 12.1.0-12.1.5) that abuses the improper authorization (CWE-285) check to escalate privileges. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict and must be weighed carefully. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with the ability to reach the Db2 query interface - for example a low-privileged database user or a network client able to authenticate - submits a specially crafted query that triggers the improper authorization check, granting them elevated privileges and full read/write control over database contents. Because SSVC marks the technique as automatable, the query could be embedded in a script and run against many instances; no public exploit code is identified at time of analysis. |
| Remediation | Apply the IBM-provided fix referenced in the vendor advisory at https://www.ibm.com/support/pages/node/7282949; patch available per vendor advisory, but an exact fixed build/fixpack number was not provided in this data set, so consult that IBM support node for the precise fixpack or special build for your 11.5.x or 12.1.x level and apply it. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all IBM Db2 instances running versions 11.5.0-11.5.9 or 12.1.0-12.1.5 in your environment. …
