Routeros

A cross-site scripting vulnerability is present in the hotspot of MikroTik's RouterOS on versions below 7.19.2. An attacker can inject the `javascript` protocol in the `dst` parameter. When the victim browses to the malicious URL and logs in, the XSS executes. The POST request used to login, can also be converted to a GET request, allowing an attacker to send a specifically crafted URL that automatically logs in the victim (into the attacker's account) and triggers the payload.

Mikrotik RouterOS VXLAN Source IP Improper Access Control Vulnerability. This vulnerability allows remote attackers to bypass access restrictions on affected installations of Mikrotik RouterOS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of remote IP addresses when processing VXLAN traffic. The issue results from the lack of validation of the remote IP address against configured values prior to allowing ingress traffic into the internal network. An attacker can leverage this vulnerability to gain access to internal network resources. Was ZDI-CAN-26415.

RouterOS provides various services that rely on correct verification of client and server certificates to secure confidentiality and integrity of communications. This includes OpenVPN, CAPsMAN, Dot1x (802.1X), among others. The vulnerability lies in shared certificate validation logic which uses the system certificate store that is shared and equally trusted by all system services. This causes confusion of scope, allowing any certificate authority present in the system-wide trust store to be trusted in any context (with some exceptions), allowing partial or full authentication bypass in CAPsMAN, OpenVPN, Dot1X and potentially others.
