CVE-2019-1068: A remote code execution vulnerability exists in ...

CISA added CVE-2019-1068, a high-severity remote code execution flaw in Microsoft SQL Server, to its KEV catalog after confirming exploitation in the wild.

CVE-2019-1068 (CVSS 8.8, CWE-20) is an improper input validation flaw allowing unauthenticated RCE in Microsoft SQL Server 2014 SP2/SP3, 2016, and 2017 on 32-bit and x64 builds. Exploitation requires low complexity and low privileges with no user interaction, and CISA formally added it to the KEV catalog on August 26, 2026. The CVE was originally published on July 15, 2019 and carries an EPSS score of 52.8%. Administrators must inventory affected SQL Server assets and apply vendor patches on an accelerated timeline.

CISA Warns of Microsoft SQL Server RCE Vulnerability Exploited in Attacks

    CVE-2019-1068 is a remote code execution vulnerability in Microsoft SQL Server caused by improper handling of the processing of internal functions (CWE-20, improper input validation). An attacker who can reach SQL Server over the network with low-privileged credentials can trigger the flawed code path and execute arbitrary code, gaining high confidentiality, integrity, and availability impact on the database host. Any organization running affected Microsoft SQL Server versions — including SQL Server 2016 and SQL Server 2017 — is affected. The flaw carries a high EPSS score (52.8% probability of exploitation within 30 days, 99th percentile) and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-26, with headlines reporting it being exploited in active attacks. No public proof-of-concept is known, but the in-the-wild exploitation documented by CISA makes patching urgent; the fix shipped in Microsoft's July 2019 Patch Tuesday security updates.
