Overview
The vulnerability CVE-2025-57060 is a serious cybersecurity issue that primarily affects Tenda G3 version 3.0br_V15.11.0.17. This vulnerability revolves around a stack overflow in the rules parameter within the dns_forward_rule_store function. A successful exploit can lead to a Denial of Service (DoS) attack, which can potentially compromise the system and lead to data leakage.

A new way to communicate
Ameeba Chat is built on encrypted identity, not personal profiles.
Message, call, share files, and coordinate with identities kept separate.
- • Encrypted identity
- • Ameeba Chat authenticates access
- • Aliases and categories
- • End-to-end encrypted chat, calls, and files
- • Secure notes for sensitive information
Private communication, rethought.

How the Exploit Works
The vulnerability works by exploiting a stack overflow in the rules parameter of the dns_forward_rule_store function within Tenda G3. When a maliciously crafted request is sent, it causes the system to overflow, leading to a Denial of Service. This can potentially compromise the system and result in data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This example is a simple HTTP request that sends a malicious payload to the vulnerable endpoint.
POST /dns_forward_rule_store HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "rules": "OVERLY_LONG_STRING_OVERLY_LONG_STRING_OVERLY_LONG_STRING" }In this example, the `OVERLY_LONG_STRING` would be replaced with a string long enough to cause a stack overflow in the targeted system. This would result in a Denial of Service and potentially open up further avenues for exploitation.
