Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

TensorFlow | v2.18.0

How the Exploit Works

The vulnerability is triggered when padding is set to ‘valid’ in tf.keras.layers.Conv2D within TensorFlow v2.18.0. This incorrect configuration can lead to a buffer overflow condition, causing the system to become unresponsive, leading to a Denial of Service (DoS) situation. Attackers can exploit this vulnerability remotely over a network connection, without requiring any user interaction.

Conceptual Example Code

The following pseudocode outlines a potential exploitation scenario:

import tensorflow as tf
# Create a maliciously configured Conv2D layer
layer = tf.keras.layers.Conv2D(64, (3, 3), padding='valid')
# Prepare a large input tensor
input = tf.random.uniform((1, 3000, 3000, 3))
# Apply the malicious layer
output = layer(input)

In this example, the attacker creates a Conv2D layer with ‘valid’ padding and applies this to a large input tensor. This can cause the system to overflow, leading to the Denial of Service (DoS) condition.

Overview

A critical vulnerability, CVE-2025-55558, has been identified in pytorch v2.7.0, which affects machine learning platforms that employ this version of the software.

Vulnerability Summary

CVE ID: CVE-2025-55558
Severity: High (CVSS: 7.5)
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Denial of Service, potential system compromise and data leakage

Affected Products

Product | Affected Versions

pytorch | v2.7.0

How the Exploit Works

The vulnerability arises when a PyTorch model, consisting of torch.nn.Conv2d, torch.nn.functional.hardshrink, and torch.Tensor.view-torch.mv(), is compiled by Inductor. The process results in a buffer overflow if the model’s input is not correctly validated. This buffer overflow could then be exploited by an attacker to cause a denial of service, possibly compromising the system or leaking data.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This pseudocode depicts a scenario where a malicious payload triggers the buffer overflow:

# Malicious payload
payload = "A" * 10000  # Oversized input
# PyTorch model
model = torch.nn.Sequential(
torch.nn.Conv2d(1, 64, kernel_size=3, stride=1, padding=1),
torch.nn.functional.hardshrink(),
torch.Tensor.view(-1).mv(payload)  # Trigger buffer overflow
)
# Compile with Inductor
inductor.compile(model)

This code would trigger a buffer overflow in the system running this version of pytorch, leading to a Denial of Service (DoS).

Mitigation

Users are advised to apply the vendor-provided patch as soon as possible to correct this vulnerability. As a temporary mitigation strategy, users can deploy a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to help identify and block exploit attempts.

Overview

The vulnerability CVE-2025-55557 is a critical flaw in the pytorch v2.7.0 application, which can result in Denial of Service (DoS) attacks. This exploitation occurs when a PyTorch model consists of torch.cummin and is compiled by Inductor. The vulnerability affects all systems running pytorch v2.7.0.

Severity: High (7.5 CVSS)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Denial of Service, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

pytorch | v2.7.0

How the Exploit Works

The exploit takes advantage of a Name Error in pytorch v2.7.0. When a PyTorch model that includes torch.cummin is compiled by Inductor, an error is triggered. This error can be exploited to cause a Denial of Service. In some cases, this DoS condition may be leveraged by attackers to compromise the system or leak sensitive data.

Conceptual Example Code

Here is a pseudocode representation of how the vulnerability might be exploited:

# Create a PyTorch model with torch.cummin
model = PyTorchModel()
model.add(torch.cummin)
# Compile the model with Inductor
compiled_model = InductorCompiler.compile(model)
# The above operation triggers a Name Error, leading to DoS

Note: The above code is a conceptual representation. The actual exploit might involve the delivery of malicious payloads over the network, potentially through an API endpoint that uses the vulnerable PyTorch model.

Mitigation

To mitigate this vulnerability, apply the vendor-supplied patch immediately. If the patch cannot be applied right away, consider using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure to prevent exploit attempts.

Affected Products

Product | Affected Versions

PyTorch | v2.7.0

How the Exploit Works

The exploit works by taking advantage of a syntax error in the proxy_tensor.py component of PyTorch v2.7.0. By sending specially crafted requests or data to the vulnerable system, an attacker can cause a denial of service condition. This occurs due to the system’s inability to handle the incorrect syntax, which results in a halt or excessive consumption of system resources. This could potentially lead to a system shutdown, compromise, or data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. The attacker could craft a malicious payload that triggers the syntax error in the proxy_tensor.py component. The following pseudocode demonstrates the concept:

import torch
# Create a tensor with malicious data
malicious_tensor = torch.tensor([INVALID_SYNTAX])
# Send the malicious tensor to the proxy_tensor component
proxy_tensor.process(malicious_tensor)

The above pseudocode is conceptual and only serves to illustrate the exploitation process. The actual exploit may differ significantly depending on the context and the attacker’s intent.

User Interaction: None
Impact: Potential system compromise or data leakage due to increased CPU and memory consumption

Affected Products

Product | Affected Versions

Rack | Prior to 2.2.18

How the Exploit Works

The vulnerability lies in the Rack::QueryParser module which enforces its params_limit only for parameters separated by &, while it should also split on ;. This allows attackers to bypass the parameter count limit by using ; separators to submit more parameters than intended. The impact is increased CPU and memory usage, which can be leveraged for a denial-of-service attack.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This example uses a hypothetical HTTP request with a payload that abuses the parameter count bypass vulnerability.

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
param1=value1&param2=value2;param3=value3;param4=value4;param5=value5;...;paramN=valueN

In the above example, the attacker is sending a POST request with more parameters than the server is designed to handle, using the ; character to bypass the parameter count limit.

Mitigation

It is recommended to apply the vendor patch as soon as possible. If immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. The vulnerability has been patched in Rack version 2.2.18.

Vulnerability Summary

CVE ID: CVE-2025-26278
Severity: High (7.5 CVSS score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

dref library | v0.1.2

How the Exploit Works

The exploit works by an attacker supplying a crafted payload that pollutes the prototype of an object, which can lead to the addition or modification of an object property. This can cause unexpected behaviors in applications that rely on the affected library, leading to a Denial of Service (DoS) condition, or worse, a potential system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how an attacker could exploit this vulnerability:

// Example of a malicious payload
var payload = JSON.parse('{"__proto__": {"polluted": "Prototype Polluted"}}');
// Applying the payload to the vulnerable function
lib.set(targetObj, 'irrelevant', payload);
// Now, any object created will have the "polluted" property
var newObj = {};
console.log(newObj.polluted);  // Outputs: "Prototype Polluted"

In a real-world scenario, the payload would be more sophisticated and tailored to cause maximum disruption or to leverage the prototype pollution in a way that would lead to a system compromise or data leakage.

Remediation

The best remediation for this vulnerability is to apply the vendor-supplied patch. If the patch is not available or cannot be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. However, these should not be seen as long-term solutions, as they do not address the underlying vulnerability.

Overview

CVE-2025-59833 is a security vulnerability found in the Flag Forge Capture The Flag (CTF) platform, which leaves challenge hints exposed in plaintext. This flaw affects versions 2.1.0 to 2.2.9 and can be exploited by any user without requiring point deductions, disrupting the business logic of the platform and potentially impacting the integrity of the challenge system.

Vulnerability Summary

CVE ID: CVE-2025-59833
Severity: High (7.5 CVSS score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Undermined integrity of the challenge system, potential system compromise, and data leakage.

Affected Products

Product | Affected Versions

Flag Forge | 2.1.0 to 2.2.9

How the Exploit Works

The exploit takes advantage of the API endpoint GET /api/problems/:id. This endpoint is improperly configured to return challenge hints in plaintext within the question object, regardless of whether the user has unlocked them via point deduction. This means that any user can view all hints for free, without the necessary point deductions, thus bypassing the intended mechanism.

Conceptual Example Code

The vulnerability might be exploited using a simple HTTP request such as the following:

GET /api/problems/123 HTTP/1.1
Host: target.example.com

In this example, “123” is the id of a specific challenge. The server would then respond with the challenge data, including the hints in plaintext, regardless of the user’s actual point status.

Mitigation

A patch for this issue has been released in version 2.3.0 of the Flag Forge platform. Users are strongly recommended to update to this version or later. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation. These systems should be configured to monitor and block suspicious activity at the affected API endpoint.
