MikroTik RouterOS Integer Underflow
SeverityCVSS 9.8Critical · Remote / network
ExploitationNone reportedEPSS 0.9% chance in 30 days
The web management service in affected RouterOS versions contains an integer underflow in its HTTP request body handling that is reachable before authentication. This can be leveraged by an unauthenticated network attacker to achieve arbitrary code execution as root, or to cause a denial of service, using a single crafted request.
Detailed evidence Everything below supports the summary above. Open only what you need.
Direct intelligence-source lanes: every lane below has direct evidence for
in that Scantide intelligence collection. Lanes share the CVE as their join key; their presence together does not imply that one source explicitly referenced another source's record.
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.

Deduplicated across Scantide's structured CVE, NVD applicability, CSAF, vendor advisory, campaign and downstream product evidence. Taxonomy IDs and evidence-only identifiers are excluded from the asset count. Counts represent relationships Scantide can currently prove, not the theoretical maximum downstream ecosystem.

Only sources that directly identify or describe the queried CVE are shown here. Historical examples from MITRE CWE definitions are kept in the weakness section and are not presented as related CVEs.
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.
