Microsoft SQL Server Elevation of Privilege Vulnerability

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.38% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Microsoft SQL Server 2017 for x64-based Systems (CU31) 14.0.3560.2; Microsoft SQL Server 2017 for x64-based Systems (GDR) 14.0.2140.2; Microsoft SQL Server 2019 for x64-based Systems (CU32) 15.0.4500.2.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Microsoft SQL Server 2017 for x64-based Systems (CU31) 14.0.3560.2; Microsoft SQL Server 2017 for x64-based Systems (GDR) 14.0.2140.2; Microsoft SQL Server 2019 for x64-based Systems (CU32) 15.0.4500.2 or later.
