Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 37.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).

Deeper analysis

CVE-2026-1023, published on 2026-01-16, is a Missing Authentication vulnerability (CWE-306) affecting the Statistics Database System developed by Gotac. The flaw enables unauthenticated remote attackers to directly exploit a specific functionality to query database contents. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), reflecting high confidentiality impact with no effects on integrity or availability.

Unauthenticated remote attackers can exploit this vulnerability over the network with low attack complexity and no privileges or user interaction required. Exploitation allows them to access and retrieve database contents without authentication, potentially exposing sensitive information stored within the system.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly identifies, authorizes, and limits actions performable without identification or authentication, preventing unauthenticated access to the vulnerable database query functionality.

prevent

Requires identification and authentication for non-organizational users, blocking unauthenticated remote attackers from querying database contents.

prevent

Enforces approved authorizations for logical access to system resources, ensuring authentication is required for the exploitable database functionality.
