Horizon Alert
Summary of the vulnerability and why it matters
The OpenPLC ScadaBR system has a vulnerability that allows for the injection of malicious code through its system settings page. This flaw can lead to security breaches by enabling unauthorized actions or data manipulation. The impact can disrupt operations and compromise sensitive information.
- Vulnerable component: ScadaBR system settings
- Core weakness: Stored cross-site scripting
- Main business impact: Unauthorized access and data compromise
Attack Path
How an attacker could exploit the issue
An attacker can exploit a stored cross-site scripting vulnerability in ScadaBR. This allows them to inject malicious scripts into the application that are then served to other users. These scripts can perform actions on behalf of the user, potentially leading to unauthorized access or modification of system settings. This impacts organizations by risking the integrity of their operational data and control systems.
- Vulnerability exposed via web interface.
- Attacker injects script via system settings.
- Malicious script executes in user's browser.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an attacker with limited access to an organization's network to execute malicious scripts within the web browser of another user. This could lead to the theft of sensitive information or the modification of data viewed by the user. The attacker's skill level is considered low, and exploitation requires specific user interaction, making the immediate business risk moderate. However, given its inclusion in a known exploited vulnerabilities catalog, organizations should prioritize addressing this.
- Attacker skill level: Low.
- Required access or conditions: Limited user access and user interaction.
- Business risk or urgency: Moderate, but treat as urgent.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
