Use of uninitialized resource in SQL Server allows an authorized attacker to disclose information over a network.
AnalysisAI
Uninitialized memory exposure in Microsoft SQL Server 2017 through 2025 allows a network-authenticated low-privilege attacker to read sensitive server-side data. The root cause is CWE-908 (Use of Uninitialized Resource), where a memory region is accessed before initialization, potentially leaking residual contents from query buffers, session state, or internal structures. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid SQL Server login with at least low-privilege access (PR:L per CVSS:3.1 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 base score reflects a network-accessible, low-complexity attack constrained by a required low-privilege SQL Server login (PR:L), with high confidentiality impact and no integrity or availability consequence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patches per branch: SQL Server 2017 GDR to 14.0.2130.4 or later, SQL Server 2017 CU31 to 14.0.3550.4 or later, SQL Server 2019 GDR to 15.0.2190.7 or later, SQL Server 2019 CU32 to 15.0.4490.9 or later, SQL Server 2022 GDR to 16.0.1200.5 or later, SQL Server 2022 CU26 to 16.0.4275.2 or later, SQL Server 2025 GDR to 17.0.1135.8 or later, and SQL Server 2025 CU8 to 17.0.4085.5 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
