CyberRota Analysis
AI-GeneratedA vulnerability exists in Tabby versions prior to 1.0.235, where a malicious SFTP server can exploit backslash traversal in filenames, leading to unauthorized file creation or overwriting outside designated directories on Windows systems. This flaw arises from improper handling of path processing, allowing attackers to manipulate file paths. Organizations using affected versions of Tabby should prioritize updating to version 1.0.235 or later to mitigate potential security risks.

Original NVD Description
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.235, a malicious SFTP server can return a backslash traversal filename through entry.name. In tabby-ssh/src/session/sftp.ts, SFTPSession.readdir() and _makeFile() use POSIX path processing that preserves the backslashes as ordinary filename characters. In tabby-ssh/src/components/sftpPanel.component.ts, downloadFolderRecursive() propagates item.name into the local relative path. In tabby-electron/src/services/platform.service.ts, ElectronDirectoryDownload.createFile() passes that path to Windows-native path.join(), and in tabby-electron/src/sftpContextMenu.ts, EditSFTPContextMenu.edit() passes item.name to path.join() for the temporary edit path. Windows interprets the preserved backslashes and parent-directory components as traversal, allowing attacker-controlled content to be created or overwritten outside the selected download directory or temporary edit directory. This issue is fixed in version 1.0.235.
