What the vulnerability is

A vulnerability was identified in MikroTik RouterOS 6.49.8. This vulnerability affects the function ASN1_STRING_data in the library nova/lib/www/scep.p of the component SCEP Endpoint. The manipulation of the argument transactionID/messageType leads to out-of-bounds read. The attack may be initiated remotely. The exploit is publicly available and might be used. You should upgrade the affected component. The vendor recommends to "use the latest v6.x or 7.x MikroTik RouterOS version, the reported issue should be fixe…

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.

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.
