Summary

Appium and its @appium/support npm package before 7.2.6 mishandle ZIP extraction. An archive entry can create a symbolic link to a location outside the extraction directory, and a later regular-file entry then writes through that link (CWE-59). Because the containment check examines only entry names, an attacker-controlled archive can write files to arbitrary locations the Appium process can write to, which can overwrite configuration or executables and lead to code execution.

Description from the CNA

Appium is a cross-platform automation framework for all kinds of apps, built on top of the W3C WebDriver protocol. Prior to 7.2.6, @appium/support ZIP extraction accepts an archive entry that creates a symbolic link to a location outside the extraction directory and then accepts a later regular-file entry whose legitimate name resolves through that link. The lexical containment check examines entry names without validating the symlink target or the real destination, so an attacker-controlled archive can write files to arbitrary locations writable by the Appium process. This is distinct from the earlier parent-directory entry-name traversal fixed in 7.0.6 because the bypass uses no parent-directory or absolute entry name. Depending on the writable destination, the arbitrary file write can overwrite configuration, startup scripts, or executables and lead to code execution. This issue is fixed in version 7.2.6.
