1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-0960 CVSS Score: 9.8

The vulnerability in AutomationDirect C-more EA9 HMI involves a function with bounds checks that can be bypassed, potentially leading to a denial-of-service (DoS) condition or remote code execution (RCE). The high CVSS score of 9.8 indicates a critical severity level, reflecting the potential for significant impact on affected systems.

Severity Evaluation:

• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: High

The vulnerability's ability to cause DoS or RCE makes it a high-priority issue for immediate attention and remediation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: An attacker could exploit this vulnerability over the network by sending specially crafted packets to the affected HMI device.
• Local Exploitation: If an attacker gains local access to the HMI, they could manipulate the function to bypass bounds checks and execute arbitrary code.

Exploitation Methods:

• Buffer Overflow: By sending malformed data, an attacker could overflow the buffer, leading to code execution or a crash.
• Memory Corruption: Exploiting the bounds check bypass could result in memory corruption, allowing the attacker to inject malicious code.

3. Affected Systems and Software Versions

Affected Systems:

• AutomationDirect C-more EA9 HMI devices

Software Versions:
