Mēris botnet
In early September 2021 QRATOR labs published an article about a new wave of DDoS attacks, which are originating from a botnet involving MikroTik devices. As far as we have seen, these attacks use the same routers that were compromised in 2018, when MikroTik RouterOS had a vulnerability, that was quickly patched. There is no […]
Fragattacks
In beginning of May 2021, a security research group from Belgium published a set of vulnerabilities they call “Frag Attacks” (from Fragmentation Attack), which affect all modern security protocols of Wi-Fi. Not all the published issues affect MikroTik products, but those that were found to be potentially affecting RouterOS, have been fixed in all currently released […]
Upgraded package signatures
The RouterOS package signing procedure has been upgraded, to use new algorithms and utilize state of the art security hardware. It will also add a possibility to verify the integrity of existing installations. The new updated package signing procedure provides additional security to prevent installation of malicious software. Best security practices: Keep RouterOS updated to the […]
CVE-2019-3981
Summary Tenable has published a potential vulnerability in older RouterOS versions where an attacker can retrieve the password hash of a RouterOS username via a complex man-in-the-middle attack over port 8291. The attacker must be able to intercept a valid RouterOS user login attempt, so he must be located in the same network as the […]
DNS cache poisoning vulnerability
Tenable has identified a vulnerability in RouterOS DNS implementation. RouterOS 6.45.6 and below is vulnerable to unauthenticated remote DNS cache poisoning via Winbox. The router is impacted even when DNS is not enabled. One possible attack vector is via Winbox on port 8291 if this port is open to untrusted networks. The resolver can be […]
Package validation and upgrade vulnerability
Tenable has identified a couple of issues with RouterOS packaging and upgrade systems. The upgrade system used by RouterOS 6.45.5 and below is vulnerable to man in the middle attacks and insufficient package validation. An attacker can abuse these vulnerabilities to downgrade a router’s installed RouterOS version, possibly lock the user out of the system, […]
CVE-2019-11477, CVE-2019-11478, CVE-2019-11479
Summary Netflix has identified several TCP networking vulnerabilities in the Linux kernel that is used in RouterOS. The vulnerabilities can trigger denial of service if the RouterOS system is attacked from an insufficiently protected network interface (port). Firewall can protect against the issue. MikroTik has already applied the necessary patches: fix included in RouterOS 6.45.1 and […]
