MyNET Iframe Injection Leads to Code Execution.

CVE advisorySeverity: CRITICAL (CVSS 9.6)

CVE-2024-27708

MyNET is identified as a web-based service or solution platform. Applications serving web content and functionality are typically deployed in internet-facing configurations, making them accessible via standard web browsers and common in remote access or public-facing service architectures.

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

External exposure likelihood

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability involves an iframe injection flaw in a web-based service that could allow remote attackers to execute code. The main concern is confirming whether this specific technology is in use and exposed to potential threats.

  • Code execution possible via web service.
  • Confirms relevance and exposure of the technology.
  • Understand potential risks to web services.

Attack Path

How an attacker could exploit the issue

An attacker can target the MyNET application by sending a specially crafted request to its web interface. This request exploits a weakness in how the application handles certain parameters, allowing for the injection of malicious iframe code. If a user interacts with the compromised interface, the attacker could potentially execute arbitrary code within the context of the user's browser session.

  • No authentication or special access required.
  • Triggered by visiting a crafted URL.
  • Potential for arbitrary code execution.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an attacker to inject malicious content into the `airc.pt/solucoes-servicos.solucoes` page when it's viewed in a browser, potentially leading to the execution of arbitrary code if specific conditions are met.

  • Affected system: Web server with vulnerable software.
  • Exposure: Malicious code injected via `src` parameter.
  • Consequence: Arbitrary code execution may occur.

Operational Fix

Recommended remediation, mitigation, and detection steps

The MyNET application, specifically versions prior to 26.06, presents a critical iframe injection vulnerability. Ownership of this issue likely resides with the application or platform team responsible for MyNET, with support from the network and security teams to assess exposure. The immediate first step is to locate all instances of MyNET, determine their reachability and business criticality, and identify the accountable owner to prioritize remediation efforts.

  • Application owners must confirm deployment.
  • Verify external reachability and business impact.
  • Plan remediation based on identified risk.

Frequently asked questions

What is the airc MyNET software?

MyNET is a web-based solution platform developed by airc. It functions as a service delivery system, providing web-based content and functionality to its users. Organizations typically deploy this platform to host digital services that are accessible through standard web browsers.

What does iframe injection mean in CVE-2024-27708?

This vulnerability is classified as Improper Neutralization of Special Elements (CWE-74). It means the application fails to properly sanitize inputs, allowing an attacker to insert a malicious iframe into a web page. This flaw is dangerous because it can be leveraged to execute arbitrary code within the context of a user's browser session.

How does an attacker trigger this vulnerability?

An attacker triggers the flaw by sending a specially crafted request containing a malicious src parameter to the MyNET web interface. Note that this attack does not require the user to have special administrative access or authentication to the system; simply visiting a manipulated URL can initiate the exploit path.

Is my instance of MyNET at risk?

According to Halo Surface Signal, MyNET is a web-based service often deployed in internet-facing configurations for public access. Because these services are designed to be reachable via the internet, any instance running a version of 26.06 or earlier is considered to have a higher potential for external exposure.

What should I do if I use MyNET?

First, conduct an inventory to identify all instances of MyNET across your environment. Once located, verify the version number to see if it falls at or below 26.06. Coordinate with your application owners to determine the business criticality of these instances and prioritize them for updates or security hardening.
