Mikrotik Routeros Authentication Bypass Vulnerability
user.dat contains the admin password hashed with MD5 (older) or PBKDF2 (newer, but vulnerable in 6.x).
In June 2023, a authentication bypass was disclosed affecting RouterOS versions 6.40.9 through 6.48.6 . This vulnerability targets the HTTP/Webfig interface rather than WinBox.
CVE-2023-30799 has been actively exploited in the wild. Security researchers have observed:
MikroTik regularly patches vulnerabilities. Long-term or Stable release channels should be tracked closely. Upgrade your firmware via the terminal: /system package update check-for-updates download Use code with caution. mikrotik routeros authentication bypass vulnerability
Go to IP -> Services and disable winbox , www , telnet , ftp , and api if they are not needed. Restrict Access to Management Interfaces: Do not expose WinBox/WebFig to the public internet.

An authentication bypass in MikroTik RouterOS allows attackers to circumvent the standard login process (WinBox, WebFig, or SSH), gaining administrative control over the router without a valid username or password. This article explores the nature of these vulnerabilities, recent examples, and the critical steps for securing your infrastructure. What is a MikroTik RouterOS Authentication Bypass? CVE-2023-30799 has been actively exploited in the wild
Security researchers discovered that the parsing mechanism for these messages contained a directory traversal vulnerability. By crafting a specific request, an attacker could trick the router into reading files outside the intended web or protocol directory. 2. Remote Credential Extraction
If the attacker has limited access (e.g., CVE-2023-30799), they can escalate to Super Admin .
Understanding the MikroTik RouterOS Authentication Bypass Vulnerability Upgrade your firmware via the terminal: /system package
is a privilege escalation vulnerability in RouterOS that allows an authenticated administrator to bypass security restrictions and obtain super-admin (root) privileges . The vulnerability was first discovered in June 2022 at the REcon security conference by Margin Research employees Ian Dupont and Harrison Green, who released an exploit called FOISted capable of obtaining a root shell on RouterOS x86 virtual machines.
An unauthenticated attacker can bypass login credentials and gain to a MikroTik router by sending a specially crafted packet to the WinBox or HTTP management ports (default: 8291, 80, 443).
Changing user credentials, creating backdoors, or altering firewall rules to redirect traffic. How to Protect Your MikroTik Router
is a recently disclosed authentication bypass vulnerability affecting RouterOS versions 7.20.x and lower . The flaw resides in the shared certificate validation logic used by multiple RouterOS services, including OpenVPN, CAPsMAN (Controlled Access Point System Manager), and 802.1X authentication systems.
