- CWE-345 - Insufficient Verification of Data Authenticity
Summary
MobaXterm Personal Edition (Portable) 26.4 GA extracts the CygUtils64.plugin file without first verifying its integrity. A local attacker with write permissions on this file can replace the ‘bin/cygwin1.dll’ library contained within it with a malicious library. When the victim opens a Local Shell session or uses a Cygwin-based function, the application extracts the component and loads the tampered library, executing code with the victim’s permissions. Exploitation requires write access to the plugin and does not, in itself, involve privilege escalation.

CWE
- CWE-428 - Unquoted search path or element
Summary
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 order, resulting in arbitrary code execution in the context of the affected user.

CWE
- CWE-1204 - Generation of Weak Initialization Vector (IV)
Summary
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. A derivative of the password is used as the master key. As both the master key and the IV are the same for each stored password, the AES CFB ciphertext depends only on the plaintext (the password). The static IV and master key make it easier to obtain sensitive information and to decrypt data when it is stored at rest.
