Routeros

An issue was discovered in the Winbox service of MikroTik RouterOS long-term release v6.43.13 through v6.49.13 and stable v6.43 through v7.17.2. A patch is available in the stable release v6.49.18. A discrepancy in response size between connection attempts made with a valid username and those with an invalid username allows attackers to enumerate for valid accounts.

RouterOS versions 6.45.6 Stable, 6.44.5 Long-term, and below are vulnerable to a DNS unrelated data attack. The router adds all A records to its DNS cache even when the records are unrelated to the domain that was queried. Therefore, a remote attacker controlled DNS server can poison the router's DNS cache via malicious responses with additional and untrue records.

RouterOS 6.45.6 Stable, RouterOS 6.44.5 Long-term, and below insufficiently validate where upgrade packages are download from when using the autoupgrade feature. Therefore, a remote attacker can trick the router into "upgrading" to an older version of RouterOS and possibly reseting all the system's usernames and passwords.
