Vulnerabilidades

MobaXterm Personal Edition (Portable), in its 26.3 version (Build 5154), allows arbitrary code execution by loading a malicious DLL located in the same directory as the portable executable. Because the application automatically loads the winspool.drv library from that location during startup, an attacker with local…

MobaXterm Personal Edition (Portable), in its 26.3 version (Build 5154), allows arbitrary code execution by loading malicious DLLs from a temporary directory that is predictable and can be modified by the user. During startup, the application searches for specific DLLs in this location before resorting to the system’s…

Mobatek MobaXterm 12.1 contains a structured exception handling (SEH) based buffer overflow vulnerability in the username field of session files that allows remote attackers to execute arbitrary code. Attackers can craft a malicious MobaXterm sessions file with overflow data that triggers the vulnerability when…

A vulnerability has been found in Mobatek MobaXterm Home Edition up to 26.1. This affects an unknown part in the library msimg32.dll. The manipulation leads to uncontrolled search path. An attack has to be approached locally. The attack is considered to have high complexity. It is indicated that the exploitability is…

MobaXterm versions prior to 26.1 contain an uncontrolled search path element vulnerability. The application calls WinExec to execute Notepad++ without a fully qualified executable path when opening remote files. An attacker can exploit the search path behavior by placing a malicious executable earlier in the search…

The vulnerability exists in the password storage of Mobateks MobaXterm in versions below 25.0. MobaXTerm uses an initialisation vector (IV) consisting only of zero bytes and a master key to encrypt each password individually. In the default configuration, on opening MobaXTerm, the user is prompted for their password.…

When aborting a SFTP connection, MobaXterm before v22.1 sends a hardcoded password to the server. The server treats this as an invalid login attempt which can result in a Denial of Service (DoS) for the user if services like fail2ban are used.

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.

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 or SetWindowTextW calls.

In MobaXterm 11.1 and 12.1, the protocol handler is vulnerable to command injection. A crafted link can trigger a popup asking whether the user wants to run MobaXterm to handle the link. If accepted, another popup appears asking for further confirmation. If this is also accepted, command execution is achieved, as…

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. Based on the available command-line arguments of the software, one can simply inject -exec to execute arbitrary commands. The…

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 the remote SSH server. This affects Passwordless Authentication that has a Password Protected SSH Private Key.

The TELNET service in Mobatek MobaXterm 10.4 does not require authentication, which allows remote attackers to execute arbitrary commands via TCP port 23.

Directory traversal vulnerability in the TFTP server in MobaXterm Personal Edition 9.4 allows remote attackers to read arbitrary files via a .. (dot dot) in a GET command.

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 attackers to execute arbitrary commands or obtain sensitive information via X11 packets.
