Microsoft Sql Server 2025 Cu 6
Monthly
Privilege elevation in Microsoft SQL Server (2016 SP3 through 2025) allows an authenticated attacker to inject crafted SQL commands over the network and gain higher database privileges (CVSS 8.8). The flaw is a classic improper neutralization of special elements (CWE-89) reachable by any principal already holding low-level database access. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV, though a vendor patch is available.
Privilege escalation via external file path control in Microsoft SQL Server affects versions 2016 through 2025, exploitable by any low-privilege authenticated SQL Server user. CWE-73 (External Control of File Name or Path) allows an authorized attacker to supply or manipulate file path parameters - likely through SQL operations such as BULK INSERT, BACKUP/RESTORE, or FILESTREAM commands - to escape intended access boundaries and elevate local operating system or SQL Server privileges. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; however, the SSVC framework rates Technical Impact as total, indicating full system compromise is achievable upon successful exploitation. The EPSS score of 0.24% (15th percentile) reflects low current exploitation probability.
Remote code execution in Microsoft SQL Server (2016 SP3 through 2025) arises from unsafe deserialization of untrusted data (CWE-502), letting an attacker who can reach the database over the network run arbitrary code in the SQL Server process context. Microsoft rates it critical (CVSS 9.8) and has shipped fixes across all supported branches; there is no public exploit identified at time of analysis and CISA SSVC lists exploitation as none. EPSS is modest at 1.29% (67th percentile), consistent with a serious-but-not-yet-exploited server-side flaw.
Remote code execution in Microsoft SQL Server 2025 (GDR builds 17.0.1050.2 to 17.0.1125.2 and CU 6 line 17.0.4060.2) arises from unsafe deserialization of untrusted data (CWE-502), letting an authorized attacker run arbitrary code over the network with total impact to confidentiality, integrity, and availability. Microsoft, the reporting party, rates it CVSS 9.8, though the description's 'authorized attacker' wording conflicts with the vector's PR:N and should be verified. There is no public exploit identified at time of analysis, EPSS is a moderate 1.29% (67th percentile), and CISA SSVC records exploitation status as none.
SQL injection in Microsoft SQL Server (versions 2016 through 2025) enables an authenticated attacker to escalate privileges on the database server. The flaw, tracked as CWE-89, exists within the SQL Server engine's handling of user-supplied SQL input, allowing insufficient neutralization to be leveraged for privilege elevation. Publicly available exploit code exists (GitHub gist), though CISA has not yet added this to the KEV catalog and SSVC indicates no confirmed active exploitation; EPSS sits at 0.57% (44th percentile), suggesting low but non-trivial opportunistic exploitation risk.
Type confusion (CWE-843) in Microsoft SQL Server 2025 enables authenticated, low-privileged network attackers to disclose sensitive server-side information. The CVSS vector (AV:N/PR:L/C:H) confirms that any authorized database user - regardless of their data access permissions - can potentially trigger the flaw remotely with no user interaction required. No public exploit code or CISA KEV listing exists at time of analysis, but the high confidentiality impact and low access complexity make patching a meaningful priority for organizations running SQL Server 2025.
Buffer over-read in Microsoft SQL Server 2025 exposes server memory contents to low-privileged authenticated attackers over the network, resulting in high confidentiality impact with no integrity or availability consequences. Both the Cumulative Update 6 (CU 6) and General Distribution Release (GDR) servicing tracks on x64-based systems are confirmed affected per vendor CPE data. No public exploit has been identified and CISA has not listed this in KEV; SSVC assessment corroborates no active exploitation at time of analysis, placing this in a measured but real priority category for environments handling sensitive SQL data.
