CVE-2026-67278MEDIUM · 6.3
Published 2026-09-06 01:47 IST · Network devices

MikroTik RouterOS accepts malformed RSA/PKCS#1 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 the root’s public certificate - without its private key - to forge a trusted intermediate and issue certificates for arbitrary host…

CVE-2026-67281HIGH · 8.7
Published 2026-09-06 01:47 IST · Network devices

RouterOS WebFig contains an unauthenticated file-read vulnerability in the /jsproxy path where a newly allocated session retains a stale uninitialized principal pointer used for file authorization. An unauthenticated attacker can prepare the allocator so that the file-serving path dereferences this pointer with sufficient rights, then supply parent-directory components in an encrypted URI to escape the WebFig file namespace a…

CVE-2026-67277HIGH · 8.8CISA KEV
Published 2026-09-06 01:47 IST · LinuxNetwork devices

RouterOS accepts a "related" btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate unchecked, inverted packet-size interval causes unsigned integer underflow, anomalously large fragmented output, and can restart th…

CVE-2026-67279MEDIUM · 6.9CISA KEV
Published 2026-09-06 01:47 IST · Network devices

RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request. On affected builds the server dispatches the command, enabling unauthenticated creation, overwrite, and reconstruction of files in the RouterOS managed file namespace, including support files containing configurati…

Published 2026-09-06 01:47 IST · Network devices

RouterOS contains an argument-handling flaw in the SSH login path involving usernames that begin with a prohibited character, allowing for the trusted RouterOS policy mask to be changed, leading to privilege escalation. Exploitation requires an unauthenticated SSH session to reach the RouterOS login helper.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable)

CVE-2026-67276CRITICAL · 9.2
Published 2026-09-06 01:47 IST · Network devices

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 supply a key with exponent one, forge a valid signature, and open an SSH command channel as the target user without the private key.…

CVE-2026-75925CRITICAL · 9.4
Published 2026-09-05 03:47 IST · Network devices

Improper neutralization of CRLF sequences in IXON VPN Client before version 1.4.7 allows an attacker to execute commands as root or SYSTEM. Configuration values accepted by the local service are written to a file later consumed by a privileged subprocess, without line-ending sequences being neutralized, which allows additional directives to be introduced into that file. The configuration interface accepts changes without auth…

nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.7.1, revocation is the only in-band mechanism that isolates a compromised/offboarded host from a Nebula mesh. Because the blocklist never reaches any peer's config.yml, a Blocked host retains full overlay reachability to every peer under its CA (and internal services on the mesh) for up to 30d (agent) / 365d (mobile). An attacker who exfi…
