Clinic Image System Hard-coded Credentials Allow Unauthenticated Administrator Login.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2025-8857

The Clinic Image System is a web-based application designed for clinical environments. Applications of this type are frequently deployed as internet-facing portals or edge services to allow remote access for staff or integration with external systems, making it likely that the login interface and its associated hard-coded credentials are reachable from the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in the Clinic Image System, which allows unauthorized remote attackers to gain administrator access by using hard-coded credentials. This presents a significant security risk to systems using this technology.

  • Unauthenticated access to administrator functions.
  • Protects patient data and system integrity.
  • Confirm system relevance and assess exposure.

Attack Path

How an attacker could exploit the issue

An unauthenticated remote attacker can gain administrative access to the Clinic Image System by leveraging hard-coded credentials embedded within the application's source code. This allows the attacker to bypass authentication and log directly into the system with full privileges.

  • No authentication or special access needed.
  • Uses hard-coded administrator credentials.
  • Full administrative control of the system.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could expose the Clinic Image System to unauthorized access. Unauthenticated remote attackers can log in as administrators using hard-coded credentials found in the source code.

  • System administrator access could be compromised.
  • Attackers could exploit embedded credentials remotely.
  • Sensitive clinical data could be exposed or modified.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Clinic Image System's hard-coded credentials present a critical risk that requires immediate attention. Application owners, in coordination with infrastructure and security teams, must prioritize identifying all instances of this system. The immediate first step is to determine the system's reachability and business criticality to accurately assess the exposure before planning remediation.

  • Application owners are responsible for this issue.
  • Verify system reachability and business criticality.
  • Plan remediation based on confirmed risk.

Frequently asked questions

What is the Clinic Image System?

The Clinic Image System is a software application designed for clinical environments to manage medical imaging data. It functions as a specialized platform for healthcare providers to store, retrieve, and view patient images, often serving as a centralized hub for diagnostic workflows.

How does CVE-2025-8857 work?

This vulnerability is classified as Use of Hard-coded Credentials (CWE-798). It means the developers included static administrator usernames and passwords directly within the software's source code. Because these credentials cannot be changed by users, anyone who knows them can bypass the login screen and gain full administrative control.

Do I need special access to trigger CVE-2025-8857?

No. The vulnerability does not require any prior authentication, special user privileges, or complex preconditions to exploit. If the login portal is reachable, an attacker can simply input the embedded hard-coded credentials to gain access. Legitimate user actions or specific system configurations are not required for the exploit to succeed.

Is my Clinic Image System instance at risk?

According to Halo Surface Signal, this software is frequently deployed as an internet-facing portal or edge service to facilitate remote staff access. If your installation is accessible via the public internet, it faces a higher probability of being reached and exploited by remote attackers compared to systems strictly isolated within an internal network.

When should I take action regarding this vulnerability?

You should act immediately. Your first step is to verify whether your deployment is reachable from the internet and evaluate its business criticality. Coordinate with your security or infrastructure teams to identify all instances of the software and confirm if your specific environment exposes these administrative functions to unauthorized users.
