Routeros

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."

Mikrotik RouterOS RADVD Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Mikrotik RouterOS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Router Advertisement Daemon. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-19797.
