Vulnerability from github – Published: 2025-08-05 21:31 – Updated: 2025-09-03 15:30
VLAI
Details

FreeFloat FTP Server contains multiple critical design flaws that allow unauthenticated remote attackers to upload arbitrary files to sensitive system directories. The server accepts empty credentials, defaults user access to the root of the C:\ drive, and imposes no restrictions on file type or destination path. These conditions enable attackers to upload executable payloads and .mof files to locations such as system32 and wbem\mof, where Windows Management Instrumentation (WMI) automatically processes and executes them. This results in remote code execution with SYSTEM-level privileges, without requiring user interaction.

GHSA-25QR-6MPR-F7QX

Vulnerability from github – Published: 2026-04-22 14:44 – Updated: 2026-06-08 20:09
VLAI
Summary
Rclone: Unauthenticated options/set allows runtime auth bypass, leading to sensitive operations and command execution
Details

Summary

The RC endpoint options/set is exposed without AuthRequired: true, but it can mutate global runtime configuration, including the RC option block itself. An unauthenticated attacker can set rc.NoAuth=true, which disables the authorization gate for many RC methods registered with AuthRequired: true on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods.

Preconditions

Preconditions for this vulnerability are:

  • The rclone remote control API must be enabled, either by the --rc flag or by running the rclone rcd server
  • The remote control API must be reachable by the attacker - by default rclone only serves the rc to localhost unless the --rc-addr flag is in use
  • The rc must have been deployed without global RC HTTP authentication - so not using --rc-user/--rc-pass/--rc-htpasswd/etc

Details

The root cause is present from v1.45 onward. Some higher-impact exploitation paths became available in later releases as additional RC functionality was introduced.

The issue is caused by two properties of the RC implementation:

  1. options/set is exposed without AuthRequired: true
  2. the RC server enforces authorization for AuthRequired calls using the mutable runtime value s.opt.NoAuth

Relevant code paths:

  • fs/rc/config.go
  • registers options/set without AuthRequired: true

  • rcOptionsSet reshapes attacker-controlled input into global option blocks

  • fs/rc/rcserver/rcserver.go

  • request handling checks:
    • if !s.opt.NoAuth && call.AuthRequired && !s.server.UsingAuth()
  • once rc.NoAuth is changed to true, later AuthRequired methods become callable without credentials

This creates a runtime auth-bypass primitive on the RC interface.

After setting rc.NoAuth=true, previously protected administrative methods become callable, including configuration and operational endpoints such as:

  • config/listremotes
  • config/dump
  • config/get
  • operations/list
  • operations/copyfile
  • core/command

Relevant code for the second-stage command execution path:

  • fs/metadata.go

  • metadataMapper() uses exec.Command(...)

  • fs/operations/rc.go

  • operations/copyfile is normally AuthRequired: true
  • once rc.NoAuth=true, it becomes reachable without credentials

This was validating using the following: - current master as of 2026-04-14: bf55d5e6d37fd86164a87782191f9e1ffcaafa82 - latest public release tested locally: v1.73.4

The issue was also verified on a public amd64 Ubuntu host controlled by the tester, using direct host execution (not containerized PoC execution).

PoC

Minimal reproduction

Start a vulnerable server:

rclone rcd --rc-addr 127.0.0.1:5572

No --rc-user, no --rc-pass, no --rc-htpasswd.

First confirm that a protected RC method is initially blocked:

curl -sS -X POST http://127.0.0.1:5572/config/listremotes \
  -H 'Content-Type: application/json' \
  --data '{}'

Expected result: HTTP 403.

Use unauthenticated options/set to disable the auth gate:

curl -sS -X POST http://127.0.0.1:5572/options/set \
  -H 'Content-Type: application/json' \
  --data '{"rc":{"NoAuth":true}}'

Expected result: HTTP 200 {}

Then call the same protected method again without credentials:

curl -sS -X POST http://127.0.0.1:5572/config/listremotes \
  -H 'Content-Type: application/json' \
  --data '{}'

Expected result: HTTP 200 with a JSON response such as:

{"remotes":[]}

Testing performed

This was successfully reproduced: - on the tester's ocal test environment - on a public amd64 Ubuntu host controlled by the tester

Using the public host, the following was confirmed:

  • unauthenticated options/set successfully set rc.NoAuth=true
  • previously protected RC methods became callable without credentials
  • the issue was reproducible through direct host execution

Impact

This is an authorization bypass on the RC administrative interface.

It can allow an unauthenticated network attacker, on a reachable RC deployment without global HTTP authentication, to disable the intended auth boundary for protected RC methods and gain access to sensitive configuration and operational functionality.

Depending on the enabled RC surface and runtime configuration, this can further enable higher-impact outcomes such as local file read, credential/config disclosure, filesystem enumeration, and command execution.

  "details": "### Summary\nThe RC endpoint `options/set` is exposed without `AuthRequired: true`, but it can mutate global runtime configuration, including the RC option block itself. An unauthenticated attacker can set `rc.NoAuth=true`, which disables the authorization gate for many RC methods registered with `AuthRequired: true` on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods.\n\n### Preconditions\n\nPreconditions for this vulnerability are:\n\n- The rclone remote control API **must** be enabled, either by the `--rc` flag or by running the `rclone rcd` server\n- The remote control API **must** be reachable by the attacker - by default rclone only serves the rc to localhost unless the `--rc-addr` flag is in use\n- The rc must have been deployed **without** global RC HTTP authentication - so not using `--rc-user`/`--rc-pass`/`--rc-htpasswd`/etc\n\n### Details\nThe root cause is present from v1.45 onward. Some higher-impact exploitation paths became available in later releases as additional RC functionality was introduced.\n\nThe issue is caused by two properties of the RC implementation:\n\n1. `options/set` is exposed without `AuthRequired: true`\n2. the RC server enforces authorization for `AuthRequired` calls using the mutable runtime value `s.opt.NoAuth`\n\nRelevant code paths:\n\n- [`fs/rc/config.go`](https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/config.go)\n  - registers `options/set` without `AuthRequired: true`\n  - `rcOptionsSet` reshapes attacker-controlled input into global option blocks\n\n- [`fs/rc/rcserver/rcserver.go`](https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/rcserver/rcserver.go)\n  - request handling checks:\n    - `if !s.opt.NoAuth \u0026\u0026 call.AuthRequired \u0026\u0026 !s.server.UsingAuth()`\n  - once `rc.NoAuth` is changed to `true`, later `AuthRequired` methods become callable without credentials\n\nThis creates a runtime auth-bypass primitive on the RC interface.\n\nAfter setting `rc.NoAuth=true`, previously protected administrative methods become callable, including configuration and operational endpoints such as:\n\n- `config/listremotes`\n- `config/dump`\n- `config/get`\n- `operations/list`\n- `operations/copyfile`\n- `core/command`\n\nRelevant code for the second-stage command execution path:\n\n- [`fs/metadata.go`](https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/metadata.go)\n  - `metadataMapper()` uses `exec.Command(...)`\n\n- [`fs/operations/rc.go`](https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/operations/rc.go)\n  - `operations/copyfile` is normally `AuthRequired: true`\n  - once `rc.NoAuth=true`, it becomes reachable without credentials\n\nThis was validating using the following:\n- current `master` as of 2026-04-14: `bf55d5e6d37fd86164a87782191f9e1ffcaafa82`\n- latest public release tested locally: `v1.73.4`\n\nThe issue was also verified on a public amd64 Ubuntu host controlled by the tester, using direct host execution (not containerized PoC execution).\n\n### PoC\n#### Minimal reproduction\nStart a vulnerable server:\n\n```bash\nrclone rcd --rc-addr 127.0.0.1:5572\n```\n\nNo `--rc-user`, no `--rc-pass`, no `--rc-htpasswd`.\n\nFirst confirm that a protected RC method is initially blocked:\n\n```bash\ncurl -sS -X POST http://127.0.0.1:5572/config/listremotes \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  --data \u0027{}\u0027\n```\n\nExpected result: HTTP 403.\n\nUse unauthenticated `options/set` to disable the auth gate:\n\n```bash\ncurl -sS -X POST http://127.0.0.1:5572/options/set \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  --data \u0027{\"rc\":{\"NoAuth\":true}}\u0027\n```\n\nExpected result: HTTP 200 `{}`\n\nThen call the same protected method again without credentials:\n\n```bash\ncurl -sS -X POST http://127.0.0.1:5572/config/listremotes \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  --data \u0027{}\u0027\n```\n\nExpected result: HTTP 200 with a JSON response such as:\n\n```json\n{\"remotes\":[]}\n```\n\n#### Testing performed\nThis was successfully reproduced:\n- on the tester\u0027s ocal test environment\n- on a public amd64 Ubuntu host controlled by the tester\n\nUsing the public host, the following was confirmed:\n\n- unauthenticated `options/set` successfully set `rc.NoAuth=true`\n- previously protected RC methods became callable without credentials\n- the issue was reproducible through direct host execution\n\n### Impact\nThis is an authorization bypass on the RC administrative interface.\n\nIt can allow an unauthenticated network attacker, on a reachable RC deployment without global HTTP authentication, to disable the intended auth boundary for protected RC methods and gain access to sensitive configuration and operational functionality.\n\nDepending on the enabled RC surface and runtime configuration, this can further enable higher-impact outcomes such as local file read, credential/config disclosure, filesystem enumeration, and command execution.",

Mitigation
Architecture and Design
  • Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
  • Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
  • In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation
Architecture and Design
  • Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
  • In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
Implementation System Configuration Operation

When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].

CAPEC-12: Choosing Message Identifier

This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.

CAPEC-166: Force the System to Reset Values

An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.

CAPEC-216: Communication Channel Manipulation

An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.

CAPEC-36: Using Unpublished Interfaces or Functionality

An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.

CAPEC-62: Cross Site Request Forgery

An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
