MikroTik RouterOS 7.9 < 7.23.4 / 7.24.x < 7.24.2 SSH Authentication Bypass (CVE-2026-67276)

According to its self-reported version, the remote networking device is running a version of MikroTik RouterOS 7.9 prior to 7.23.4, or 7.24.x prior to 7.24.2. It is, therefore, affected by an authentication bypass vulnerability. RouterOS does not compare the complete RSA public key when matching ...

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...

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...

Name of the Vulnerable Software and Affected Versions RouterOS versions prior to 6.49.21 RouterOS versions prior to 7.23.4 RouterOS versions prior to 7.24.2 Description An authentication bypass exists in the SSH public key verification process. The system fails to compare the complete RSA public...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001041)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001041 advisory. The mpipowm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to caus...

Linux Distros Unpatched Vulnerability : CVE-2020-26939

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In Legion of the Bouncy Castle BC before 1.61 and BC-FJA before 1.0.1.2, attackers can obtain sensitive information about a private exponent because of Observab...
