How the Exploit Works

The exploit operates by tricking a user into mounting a maliciously crafted AFP network share. This share contains code that the macOS system misinterprets, leading to system termination. This termination could potentially leave the system in a compromised state or allow for data leakage.

Conceptual Example Code

The following pseudocode represents a conceptual example of how the exploit may be carried out. Please note that this pseudocode is intended for illustrative purposes only:

# Create malicious AFP network share
create_afp_share --name malicious_share --content '/path/to/malicious_code'
# Trick user into mounting the network share
send_email --to target --subject 'Important Network Share' --body 'Please mount the following network share: afp://malicious_share'

In this example, the attacker creates a malicious AFP network share containing their code. They then trick the user into mounting the share, causing the system to execute the code and potentially result in system termination.

How the Exploit Works

The vulnerability arises from an integer overflow issue, which is not properly validated in the affected operating systems. An integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of bits. A remote attacker can exploit this vulnerability by sending specially crafted data to the affected device, causing the integer overflow and leading to a memory leak.

Conceptual Example Code

The following is a conceptual example of how this vulnerability might be exploited. This should not be taken as an actual exploit code, but rather a simplified representation of the concept:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "integer": 9223372036854775808 }

In this conceptual example, the “integer” value is set to a value greater than what can be stored in a 64-bit signed integer, causing an integer overflow. This could potentially lead to memory leak and system compromise.

How the Exploit Works

The vulnerability gets exploited when an attacker sends a specially crafted file to the user. When the user’s system parses this file, it leads to an unexpected app termination, which can compromise the system or lead to data leakage.

Conceptual Example Code

POST /upload_file HTTP/1.1
Host: vulnerable_system.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious_file.txt"
Content-Type: text/plain
{ "malicious_payload": "..." }
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In this conceptual example, an attacker sends a POST request to the vulnerable endpoint with a malicious file. When the system parses this file, it causes the app to terminate unexpectedly.

Mitigation Guidance

Users are advised to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. These tools can help detect and prevent attempts to exploit this vulnerability.

Impact: Unauthorised Administrative Account Name Change, which could lead to system compromise or data leakage.

Affected Products

Product | Affected Versions

Product 1 | Version 1, Version 2
Product 2 | Version 3, Version 4

How the Exploit Works

The vulnerability exists within the account management functionality of the affected software. An authenticated user without administrative permissions can exploit this issue by manipulating the request sent to the server to change the account name. If successful, the attacker could change the administrator account name, potentially disrupting the system’s operations or gaining unauthorized access.

Conceptual Example Code

Here is an illustrative example of how the vulnerability might be exploited using a HTTP POST request:

POST /changeAccountName HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer user_token_without_admin_permissions
{
"accountName": "admin",
"newAccountName": "new_admin"
}

In this example, a malicious user sends a POST request to the “/changeAccountName” endpoint, attempting to change the “admin” account name to “new_admin” without having proper administrative permissions. The attacker uses a valid user token for authentication, which does not have administrative permissions, thus exploiting the vulnerability.

Overview

The nimiq/core-rs-albatross, a Rust implementation of the Nimiq Proof-of-Stake protocol, is under risk of a Denial of Service (DoS) attack due to a vulnerability in the `nimiq-network-libp2p` subcrate. This vulnerability threatens any system using this protocol and can lead to potential system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-47270
Severity: High (CVSS:7.5)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise and data leakage due to memory exhaustion and node crashes

Affected Products

Product | Affected Versions

nimiq/core-rs-albatross | Versions prior to v1.1.0

How the Exploit Works

The vulnerability lies in the `Discovery` network message handling within the `nimiq-network-libp2p` subcrate. This implementation allocates a buffer based on a length value provided by the peer, without an upper limit. The length is a `u32`, thus a malicious peer can trigger allocations of up to 4 GB, potentially leading to memory exhaustion and node crashes.

Conceptual Example Code

Given the nature of this vulnerability, it would be exploited over the network rather than via a specific code. However, in concept, a malicious peer could send an exaggeratedly large `Discovery` message leading to memory exhaustion. The process might be conceptually similar to this:

let large_message = vec![0; 4_000_000_000];  // 4 GB message
let discovery_message = DiscoveryMessage::new(large_message);
peer.send(discovery_message);  // Send the message to the target peer

Please note that this is a simplified, conceptual example and the actual process of exploitation might be more complex and require deeper knowledge of the Nimiq network protocol and the Rust programming language.

Mitigation Guidance

The vendor has released a patch as version v1.1.0. It implements a limit to the discovery message size of 1 MB and also resizes the message buffer size incrementally as the data is read. Systems using nimiq/core-rs-albatross should upgrade to this version as soon as possible.
In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may provide temporary mitigation, but these are not substitutes for applying the vendor’s patch. No other known workarounds are available.

function exploit(target_address) {
// Construct a malicious packet that will cause a buffer overflow
var malicious_packet = construct_malicious_packet();
// Send the malicious packet to the target via Bluetooth or the RS-232 interface
send_packet(target_address, malicious_packet);
}
function construct_malicious_packet() {
// The actual construction of the malicious packet would depend on the specifics of the vulnerability and the target system
return "MALICIOUS_PACKET_DATA";
}
