Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Mintty is a terminal emulator for Cygwin, MSYS, and WSL. In versions 2.3.6 through 3.7.4, several escape sequences can cause the mintty process to access a file in a specific path. It is triggered by simply printing them out on bash. An attacker can specify an arbitrary network path, negotiate an ntlm hash out of the victim's machine to an attacker controlled remote host. An attacker can use password cracking tools or NetNTLMv2 hashes to Pass the Hash. Version 3.7.5 fixes the issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

In mintty versions 2.3.6 through 3.7.4, specific escape sequences printed to the terminal cause the application to access arbitrary file paths, including network paths. This can trigger NTLM authentication negotiation to attacker-controlled remote hosts, allowing capture of NetNTLMv2 hashes for offline cracking or pass-the-hash attacks.

MitigationUpgrade mintty to version 3.7.5 or later to resolve the vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify mintty is installed
    Run 'mintty --version' in a command prompt or check for mintty.exe in common installation paths such as C:\msys64\usr\bin\mintty.exe, C:\Program Files\Git\usr\bin\mintty.exe, or C:\Program Files (x86)\mintty\mintty.exe
    Affected if mintty executable is found on the system
  2. Retrieve the installed version number
    Execute 'mintty --version' and note the version string displayed (format typically shows version like 3.x.x or 2.x.x)
    Affected if version command fails or returns no output, indicating mintty may not be properly installed
  3. Compare version against affected range
    Parse the version number from the previous step and check if it falls within the range 2.3.6 through 3.7.4 (inclusive)
    Affected if version is 2.3.6, 2.3.7, 2.3.8, 2.3.9, 2.3.10, 3.0.0 through 3.7.4, or any version between these bounds

User is affected if mintty version is 2.3.6, 2.3.7, 2.3.8, 2.3.9, 2.3.10, or any version from 3.0.0 through 3.7.4 inclusive.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade mintty to version 3.7.5 or later to resolve the vulnerability.

Recommended fix Moderate confidence

Version 3.7.5 or later

  1. Identify the mintty installation source (Cygwin, MSYS2, or WSL)
  2. For Cygwin users: Run the Cygwin setup installer, search for mintty package, and update to version 3.7.5 or later
  3. For MSYS2 users: Open MSYS2 terminal and run 'pacman -Syu mintty' to update to the latest version
  4. For WSL users: Update via the underlying Linux distribution's package manager (e.g., 'sudo apt update && sudo apt upgrade' for Debian/Ubuntu-based WSL)
  5. Verify the installed version by running 'mintty --version' or checking the installed package version
  6. Restart any running mintty terminals to ensure the updated version is in use
