What the vulnerability is

MikroTik RouterOS contains a weakness in its API authentication handling that lacks effective safeguards against excessive login attempts. The system does not enforce meaningful rate-limiting, account lockout, or source-based restrictions, allowing repeated authentication failures to proceed without defensive response. In some versions, a fixed per-connection delay is present, but it can be bypassed through concurrent sessions, resulting in continued high-volume attempts. This deficiency increases the risk that an…

Affected vendor/product relationships

These vendors are derived from affected product/device evidence tied to this CVE. This is intentionally separate from the direct intelligence-source lanes above: a vendor can have affected products without Scantide having a vendor-specific advisory or Microsoft KB record for the CVE.

MikroTik RouterOS contains a weakness in its API authentication handling that lacks effective safeguards against excessive login attempts. The system does not enforce meaningful rate-limiting, account lockout, or source-based restrictions, allowing repeated authentication failures to proceed without defensive response. In some versions, a fixed per-connection delay is present, but it can be bypassed through concurrent sessions, resulting in continued high-volume attempts. This deficiency increases the risk that an attacker could eventually obtain valid credentials and gain unauthorized access to administrative services.

Affected-product scope: The product/device count is the deduplicated set Scantide can prove from its currently ingested structured records and advisory text. It is not a claim that only those products were affected; component vulnerabilities such as Log4Shell can have a much larger downstream ecosystem. Advisory and vendor references are kept clickable so additional downstream exposure can be followed to the authoritative source.
Coverage note: Scantide correlates multiple public and locally indexed intelligence sources, but no dataset or matching process is complete. Results may omit software, dependencies, affected versions or advisories, and related records do not by themselves prove that a specific installation is vulnerable. Confirm important findings against vendor guidance and the installed product and version.
