Title
Lack of integrity checks in Mobatek’s MobaXterm
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.
