CVE-2025-0814 is classified as a medium severity vulnerability due to improper input validation. This vulnerability allows attackers to send malicious IEC61850-MMS packets, potentially causing denial-of-service (DoS) conditions for the network services running on the affected product. Importantly, the core functionality of the device remains intact during such attacks.
The CVSS score of 6.9 indicates a medium severity level, which suggests that while the risk is not critical, it is significant enough that organizations should prioritize addressing it in their patch cycles. Failure to do so may lead to service interruptions and impact on operational capabilities.
As of now, there are no known exploits for this vulnerability, and it is not part of the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for impact on operations makes it essential for organizations to remain vigilant and proactive in their security measures.
Organizations should assess their exposure to CVE-2025-0814 and take appropriate actions to remediate it. This includes patching affected systems once updates are available, as well as considering additional security measures to defend against potential attacks.
Vulnerability Details
The CVE-2025-0814 vulnerability results from improper input validation, specifically regarding IEC61850-MMS packets. This vulnerability could lead to the denial of service for network services running on the device. The core functionality of the device remains unaffected during an attack.
The CVSS score of 6.9, classified as medium severity, denotes a network attack vector with low complexity and no privileges required. This indicates a relatively straightforward exploitation path that could be leveraged by attackers.
Published on February 13, 2025, organizations are encouraged to monitor for patches or updates that address this vulnerability. The CWE classification associated with this vulnerability is CWE-20.
Technical Analysis
The root cause of CVE-2025-0814 stems from improper input validation, which allows for malicious IEC61850-MMS packets to be processed without adequate checks. The attack vector is network-based, and the attack complexity is low, meaning that no specialized skills are required to exploit this vulnerability.
There is no user interaction required for this vulnerability, and it does not necessitate any privileges to execute an attack. The potential impact on availability is categorized as low, indicating that while service disruptions could occur, they may not be catastrophic.
Risk & Impact Analysis
Risk to organizations includes potential service interruptions that could affect operational stability. The medium CVSS score suggests that while the vulnerability poses a significant risk, the impact may vary based on the specific deployment of the product and its network environment.
Organizations should assess their risk exposure related to CVE-2025-0814, particularly in environments where critical network services are deployed. The urgency for remediation should be classified as moderate, given the medium severity and potential for exploitation.
