Views: 318

Overview

CVE-2025-10779 is a critical vulnerability found in specific versions of D-Link DCS-935L. This vulnerability poses a significant risk as it can be exploited remotely and may potentially lead to a system compromise or data leakage. It is particularly concerning as the affected products are no longer supported by the maintainer, meaning that users must take specific steps to protect their systems.

How the Exploit Works

The vulnerability lies in the sub_402280 function of the /HNAP1/ file. A stack-based buffer overflow can be triggered by the manipulation of the HNAP_AUTH/SOAPAction argument. This leads to an overflow of the buffer, which can allow an attacker to remotely execute arbitrary code or cause a denial of service (DoS) attack.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This pseudocode represents a HTTP request that manipulates the HNAP_AUTH/SOAPAction argument:

POST /HNAP1/ HTTP/1.1
Host: vulnerable.example.com
Content-Type: text/xml; charset="utf-8"
SOAPAction: "http://purenetworks.com/HNAP1/OverFlowBuffer"
<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<OverFlowBuffer xmlns="http://purenetworks.com/HNAP1/">
<malicious_payload> ... </malicious_payload>
</OverFlowBuffer>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Mitigation Guidance

Given the severity of this vulnerability, it is strongly recommended to apply a vendor patch as soon as possible. If a patch is not available due to the product no longer being supported, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.
