# #43469 \[SC-Low] Return value of low level call not checked can cause silent Reverts

**Submitted on Apr 6th 2025 at 21:06:47 UTC by @ZestfulHedgehog609 for** [**Audit Comp | Spectra Finance**](https://immunefi.com/audit-competition/audit-comp-spectra-finance)

* **Report ID:** #43469
* **Report Type:** Smart Contract
* **Report severity:** Low
* **Target:** <https://github.com/immunefi-team/Spectra-Audit-Competition/blob/main/src/router/Dispatcher.sol>
* **Impacts:**
  * Contract fails to deliver promised returns, but doesn't lose value

## Description

## Brief/Intro

In the `Dispatcher.sol` contract ,Return value of low level call not checked

## Vulnerability Details

In the `Dispatcher.sol` contract , in the `_dispatch(bytes1 _commandType, bytes calldata _inputs)` function , if the `command` is `Commands.TRANSFER_NATIVE`, the function does a low level call to the recipient address.The problem is however, after the call is done , its returned boolean value is not checked to see if the transfer went seccessfully or not.If the transfer was not successful, this will cause a silent revert and the transaction is marked a successful even though the recipient did not receive any ether.

## Impact Details

If the call fails (e.g., recipient is a contract that reverts or runs out of gas) or (if it is a smart contract wallet that doesn't accept native ether) ,success will be false, but the transaction continues without reverting. This can lead to:

1. Lost ETH: The transfer fails, but the rest of the function executes.
2. Inconsistent state: The contract assumes the transfer succeeded when it didn’t.

## Proof of Concept

## Proof of Concept

because the competition is not requiring to submit a mandatory Poc rule, iam not submitting a runnable Poc but if the judges require a Poc after validation ,I can definitely submit it.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://reports.immunefi.com/spectra-finance/43469-sc-low-return-value-of-low-level-call-not-checked-can-cause-silent-reverts.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
