CVE-2025-63547: High Vulnerability in Eprosima Micro-XREC-DDS Agent

CVE-2025-63547 is classified as a high-severity vulnerability affecting Eprosima Micro-XREC-DDS Agent version 3.0.1. This vulnerability allows a remote attacker to cause a denial of service by sending a crafted packet targeting the MTU length field. The CVSS score of 7.5 indicates a significant risk to organizations, particularly due to its potential to disrupt service availability.

Given the nature of this vulnerability, attackers may leverage it to disrupt operations, especially in environments where Eprosima Micro-XREC-DDS Agent is critical. Organizations using this software should prioritize remediation efforts to mitigate any potential impact this vulnerability may have on their systems.

Currently, the vulnerability is marked as deferred, which suggests that further investigation is required to assess its full impact and exploitability. Nevertheless, organizations should not delay their patching and mitigation strategies.

Organizations should prioritize patching immediately to address this vulnerability, given its potential to be exploited by attackers in the wild.

Vulnerability Details

The vulnerability arises from insufficient validation of the MTU length field in Eprosima Micro-XREC-DDS Agent v.3.0.1. The CVSS 3.1 vector string is "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", indicating that the attack vector is network-based, with low complexity and no privileges required for exploitation. The availability impact is rated as high, while confidentiality and integrity impacts are none.

This vulnerability is classified under CWE-805, suggesting that the issue relates to a lack of validation in the input processing of the MTU length field, which allows attackers to send malicious packets that may lead to a denial of service.

Published on May 1, 2026, this vulnerability highlights the importance of proper input validation in software development. Organizations using the affected version should take immediate steps to update to a patched version.

Technical Analysis

The root cause of CVE-2025-63547 lies in the failure to validate the MTU length field adequately. Attackers can exploit this flaw by crafting packets that manipulate the MTU size, leading to characteristics that the software cannot handle, thus causing a denial of service.

The attack vector is network-based, meaning that an attacker does not need physical access to launch an attack. The complexity of executing this attack is low, as it does not require any special privileges or user interaction, making it accessible even to less skilled attackers.

The confidentiality impact is rated as none, indicating that sensitive information is not at risk. Similarly, the integrity impact is also none, meaning that data is not manipulated. However, the availability impact is high, highlighting the potential for service disruption.

Risk & Impact Analysis

Risk to organizations includes potential service outages that can arise from denial of service attacks exploiting this vulnerability. The blast radius is significant, especially for organizations that rely on Eprosima Micro-XREC-DDS Agent for critical operations.

With a CVSS score of 7.5, this vulnerability represents a high risk. Organizations must consider the urgency based on the potential impact and the ease of exploitation. The EPSS score of 0.00116 indicates low probability but should not diminish the perceived risk; any unmitigated vulnerabilities can lead to exploitation.

Given the current status as deferred, organizations should still proactively assess their exposure and prepare for remediation as soon as a patch is available.

Exploitation Status

Affected Versions

The affected version is Eprosima Micro-XREC-DDS Agent v.3.0.1. Organizations should upgrade to the latest patched version as soon as it is available. If version information is missing, it is advisable to assume all versions prior to the vendor patch are vulnerable.

Mitigation & Remediation

Organizations should prioritize patching immediately to mitigate this vulnerability. Regular updates and monitoring of Eprosima Micro-XREC-DDS Agent are crucial to maintaining security posture. In the absence of a patch, organizations can implement network controls to filter potentially malicious packets and enhance monitoring to detect unusual patterns indicative of denial of service attacks.

Penetration testing can also help assess the effectiveness of current security measures and identify any additional vulnerabilities that may need attention.

Detection Guidance

To detect potential exploitation attempts, organizations should monitor logs for unusual packet sizes or anomalies in MTU length. Behavioral anomalies during network traffic can also serve as indicators of an ongoing attack. Network signatures should be updated to detect patterns that align with known denial of service attacks.

AppSecure Threat Intelligence Insight

The long-term significance of CVE-2025-63547 lies in its representation of common oversights in input validation within networked applications. Security teams should take this as a reminder to conduct thorough validation of all input parameters, particularly those that involve network communications. The trend of denial of service vulnerabilities serves as a strategic takeaway for organizations to bolster their network security measures.

Penetration testing methodology should be reviewed and updated regularly to ensure that all potential attack vectors are addressed. Additionally, organizations can benefit from understanding the landscape of vulnerabilities, including those related to denial of service, to better prepare for future threats.

Vulnerability management programs should incorporate lessons learned from vulnerabilities like CVE-2025-63547 to ensure continuous improvement in security practices.

API penetration testing can also provide insights into potential vulnerabilities in related components, ensuring a more comprehensive security posture.
