Mobaxterm

Local privilege escalation in MobaXterm before 26.1 allows authenticated users with file system write access to execute arbitrary code by DLL hijacking the Notepad++ launch process. When opening remote files, MobaXterm calls WinExec without a fully qualified path, enabling attackers to place malicious executables in the search path to achieve code execution in the victim user's context. EPSS score of 0.01% (2nd percentile) indicates low probability of imminent widespread exploitation, consistent with the local attack vector requiring pre-existing system access. No active exploitation confirmed in CISA KEV; public exploit code status unknown.

When aborting a SFTP connection, MobaXterm before v22.1 sends a hardcoded password to the server. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Use of Hard-coded Credentials vulnerability could allow attackers to gain access using credentials embedded in source code.

An access control issue in MobaXterm before v22.1 allows attackers to make connections to the server via the SSH or SFTP protocols without authentication. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. Public exploit code available and no vendor patch available.

MobaXterm before 21.0 allows remote servers to cause a denial of service (Windows GUI hang) via tab title change requests that are sent repeatedly at high speed, which results in many SetWindowTextA. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

In MobaXterm 11.1 and 12.1, the protocol handler is vulnerable to command injection. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

In MobaXterm 11.1, the mobaxterm: URI handler has an argument injection vulnerability that allows remote attackers to execute arbitrary commands when the user visits a specially crafted URL. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

In MobaTek MobaXterm Personal Edition v11.1 Build 3860, the SSH private key and its password can be retrieved from process memory for the lifetime of the process, even after the user disconnects from. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

The TELNET service in Mobatek MobaXterm 10.4 does not require authentication, which allows remote attackers to execute arbitrary commands via TCP port 23. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Directory traversal vulnerability in the TFTP server in MobaXterm Personal Edition 9.4 allows remote attackers to read arbitrary files via a .. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and EPSS exploitation probability 16.9%.

The default configuration of the server in MobaXterm before 8.3 has a disabled Access Control setting and consequently does not require authentication for X11 connections, which allows remote. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, low attack complexity.
