MikroTik router flaws allow takeover without a password

CERT Polska warns that attackers are actively exploiting a chain of critical MikroTik RouterOS flaws to seize control of routers exposed to the internet. Although the warning comes from Poland’s national cybersecurity response team, MikroTik routers are sold worldwide, including in the US. The...

Vulnerabilities in MikroTik RouterOS

MikroTik has addressed several vulnerabilities in RouterOS. The first vulnerability relates to a flaw in the SSH authentication mechanism, where the exponent of RSA keys was not verified. As a result, attackers can forge RSA signatures and gain unauthorized access via SSH. The second vulnerabilit...

The vulnerability of the SSH protocol implementation in the RouterOS operating system of MikroTik allows a hacker to bypass security restrictions and gain read-only access to data.

The vulnerability of the SSH protocol implementation in the RouterOS operating system of MikroTik is related to errors in verifying the cryptographic signature during the incorrect comparison of the RSA public key assigned to the user. Exploiting this vulnerability allows a malicious actor to...

CVE-2026-67278

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures across RSA-based services, including TLS/X.509 certificate validation and SSH host-key authentication. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use...

CVE-2026-67276

RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can...

EUVD-2026-72026

MikroTik RouterOS accepts malformed RSA/PKCS1 v1.5 signatures during X.509 validation. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use the root’s public certificate - without its private key - to forge a trusted...

CVE-2026-67276

MikroTik RouterOS is vulnerable to an SSH public-key authentication bypass (CWE-347). The server matches a presented public-key blob to an authorized key by key type and modulus only, omitting the exponent , and performs signature verification using the client-supplied key . An attacker who knows...

CVE-2026-67276 SSH user impersonation possible in Mikrotik RouterOS

RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can...
