This represents an oversized data packet sent to the vulnerable endpoint, which could trigger the buffer underrun.

Mitigation

Users are advised to update their affected systems to v1536 or later. In scenarios where immediate patching is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking malicious traffic.

Overview

The vulnerability CVE-2025-41256 highlights an improper handling of TLS certificate pinning in Cyberduck and Mountain Duck. The affected software fails to properly pin untrusted certificates, particularly self-signed ones, due to the usage of the SHA-1 hashing algorithm, which is known to be weak. This vulnerability could potentially lead to system compromise or data leakage, posing a significant risk to users and organizations who rely on these software for their operations.

Vulnerability Summary

CVE ID: CVE-2025-41256
Severity: High (7.4/10)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Cyberduck | up to 9.1.6
Mountain Duck | up to 4.17.5

How the Exploit Works

The exploiter can take advantage of this vulnerability by posing as a legitimate entity and presenting a self-signed certificate. Since the software improperly pins this untrusted certificate and stores the certificate fingerprint as weak SHA-1, it becomes susceptible to a ‘man-in-the-middle’ (MitM) attack. By intercepting and altering communications between two parties, an attacker could potentially compromise the system or leak sensitive data.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited. In this case, the attacker presents a self-signed certificate during the TLS handshake.

POST /tls-handshake HTTP/1.1
Host: target.example.com
Content-Type: application/tls-certificate
{ "certificate": "self-signed-certificate", "fingerprint": "SHA-1-fingerprint" }

Upon receiving this request, the vulnerable software would improperly pin the untrusted self-signed certificate, opening up the possibility for a ‘man-in-the-middle’ attack.

Overview

The vulnerability CVE-2025-52922, discovered in Innoshop versions up to 0.4.1, allows authenticated attackers to execute directory traversal via FileManager API endpoints.

Privileges Required: Low (Needs authenticated user access to the admin panel)
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Innoshop | up to 0.4.1

How the Exploit Works

The exploit takes advantage of the FileManager API endpoints in Innoshop that do not properly handle user-supplied input, allowing a directory traversal attack. An authenticated attacker with access to the admin panel can leverage this to map the filesystem structure, create, read, delete, and move arbitrary files on the server. This could possibly lead to unauthorized access to sensitive data, disruption of system functionality, or even a full system takeover.

Conceptual Example Code

An example of how the vulnerability might be exploited is shown below. This is a sample HTTP request to the /api/file_manager/files endpoint, which abuses the directory traversal flaw to read an arbitrary file from the server:

GET /api/file_manager/files?base_folder=../../../../etc/passwd HTTP/1.1
Host: target.example.com
Authorization: Bearer <admin_auth_token>

In this example, the attacker is attempting to read the “/etc/passwd” file, which could potentially contain sensitive information.

Mitigation

Organizations are strongly advised to apply the vendor-released patch to address this vulnerability. In the absence of a patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. They should also consider implementing least privilege principles to limit the potential impact of a breach.

Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: Information disclosure, potential system compromise or data leakage

Affected Products

Product | Affected Versions

OPPO Clone Phone | All Versions

How the Exploit Works

The exploit works by taking advantage of the weak password WiFi hotspot used for file transfers in the OPPO Clone Phone. An attacker can easily guess or crack the weak password, connect to the WiFi hotspot, and gain unauthorized access to the files being transferred. This could lead to information disclosure, including personal data, contacts, photographs, and other sensitive information stored on the device.

Conceptual Example Code

An example of how this vulnerability might be exploited is through the use of network sniffing tools, like Wireshark, to intercept the data packets being transferred over the WiFi hotspot. Below is a simplified pseudocode representation of this process:

import network_sniffer
# Initialize the network sniffer on the WiFi interface
sniffer = network_sniffer.Sniffer(interface='wifi0')
# Start sniffing packets
sniffer.start()
# Loop through captured packets
for packet in sniffer.packets:
# If packet is from OPPO Clone Phone's hotspot
if packet.source == 'OPPO Clone Phone':
# Print the packet content (i.e., the file being transferred)
print(packet.content)

This pseudocode demonstrates how an attacker can sniff network traffic from the OPPO Clone Phone’s hotspot and potentially gain unauthorized access to the files being transferred. This is a conceptual representation and actual exploitation would require more advanced techniques and tools.
