CVE lookup — correlated security and lifecycle intelligence
SSH Pre-Authentication Rekey State Bypass in MikroTik RouterOS
RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request. On affected builds the server dispatches the command, enabling unauthenticated creation, overwrite, and reconstruction of files in the RouterOS managed file namespace, including support files containing configuration and diagnostic data.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long…
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.
These CVEs are connected because CISA published them in the same advisory. This is strong contextual correlation, but does not by itself mean they form an exploit chain.
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.
