Weakness (CWE)
CWE-59: Improper Link Resolution Before File Access
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.
How to prevent it (1 mitigation)
-
Architecture and Design
Follow the principle of least privilege when assigning access rights to entities in a software system.
Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.

@xhmikosr/decompress: Path traversal via symlink chain
The decompress package for Node.js extracts archives. Prior to 10.2.2 and 11.1.4, the default decompress(input, output) API relies on lexical containment checks that do not account for the kernel following a planted symlink chain. An attacker can supply a cra…

Docker Sandboxes guest can write arbitrary macOS host files via a symlink in the virtio-fs stored-path fallback
On macOS, the virtio-fs host server used by Docker Sandboxes improperly follows symlinks when reopening an unlinked file from a stored path. A malicious guest can replace a parent directory with a symlink, escape the shared workspace, and read or modify arbit…

Arbitrary File Read and Write during Snapshot Recovery in qdrant/qdrant
qdrant/qdrant version 1.9.0-dev is vulnerable to arbitrary file read and write during the snapshot recovery process. Attackers can exploit this vulnerability by manipulating snapshot files to include symlinks, leading to arbitrary file read by adding a symlin…

Judge0 vulnerable to Sandbox Escape Patch Bypass via chown running on Symbolic Link
Judge0 is an open-source online code execution system. The application uses the UNIX chown command on an untrusted file within the sandbox. An attacker can abuse this by creating a symbolic link (symlink) to a file outside the sandbox, allowing the attacker t…

Critical 10.0CVE-2024-28185 Public exploit
Judge0 vulnerable to Sandbox Escape via Symbolic Link
Judge0 is an open-source online code execution system. The application does not account for symlinks placed inside the sandbox directory, which can be leveraged by an attacker to write to arbitrary files and gain code execution outside of the sandbox. When ex…
