Title
MikroTik RouterOS SCEP Endpoint scep.p ASN1_STRING_data out-of-bounds
Summary
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 fixed there."
