Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly prevents OS command injection by requiring validation of untrusted inputs like the public_type parameter to block crafted malicious payloads.

SI-2 Flaw Remediation good match
prevent

Mitigates the specific vulnerability in D-Link DSL-3782 v1.01 by identifying, prioritizing, and applying flaw remediation such as firmware patches in a timely manner.

AC-6 Least Privilege partial match
prevent

Limits the impact of successful command injection exploitation, which requires low privileges (PR:L), by enforcing least privilege on processes handling the vulnerable public_type parameter.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
attack.mitre.org →
Why these techniques?

OS command injection directly enables arbitrary command execution on a network device (T1059.008) via exploitation of its exposed interface (T1190).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

An OS command injection vulnerability was discovered in D-Link DSL-3782 v1.01 via the public_type parameter. This vulnerability allows attackers to execute arbitrary operating system (OS) commands via a crafted packet.

Deeper analysisAI

CVE-2025-25895, published on 2025-02-18, is an OS command injection vulnerability (CWE-78) in D-Link DSL-3782 v1.01, exploitable via the public_type parameter. The flaw enables attackers to execute arbitrary operating system commands by sending a crafted packet to the affected router.

According to its CVSS v3.1 base score of 8.0 (AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), the vulnerability can be exploited by attackers with adjacent network access and low privileges, requiring low complexity and no user interaction. Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability, potentially leading to full system control on the device.
