Description

radare2 prior to 6.1.4 contains a path traversal vulnerability in its project notes handling that allows attackers to read or write files outside the configured project directory by importing a malicious .zrp archive containing a symlinked notes.txt file. Attackers can craft a .zrp archive with a symlinked notes.txt that bypasses directory confinement checks, allowing note operations to follow the symlink and access arbitrary files outside the dir.projects root directory.

• CWE-59Improper Link Resolution Before File Access ('Link Following')The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
• CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
