CVE-2025-1471 represents a high-severity vulnerability identified in Eclipse OMR, specifically in versions 0.2.0 to 0.4.0. This vulnerability allows for a buffer overflow due to the use of a constant length buffer in some z/OS atoe print functions. If the input format string and its arguments exceed the buffer size, it can lead to a significant overflow situation. The issue was addressed starting in version 0.5.0, where the conversion buffers have been correctly sized and are checked appropriately to prevent overflows.
The CVSS score for this vulnerability is 7.1, indicating a high severity level. This is particularly concerning because the attack vector is local, and the attack complexity is low, meaning that an attacker could exploit this vulnerability without requiring special conditions. Organizations using affected versions of Eclipse OMR should take this issue seriously to mitigate potential risks.
Risk to organizations includes the potential for unauthorized access and compromise of system integrity and availability, which could lead to significant operational disruptions. Given the high CVSS score and the nature of the vulnerability, organizations should prioritize patching immediately.
As of now, there are no known public exploits or proof-of-concept (PoC) details available, which offers a slight buffer for organizations to implement necessary patches and updates. However, the absence of known exploits does not diminish the importance of immediate remediation.
Organizations should address this vulnerability in their priority patch cycle to minimize risk exposure and safeguard their systems.
Vulnerability Details
The official description of this vulnerability specifies that in Eclipse OMR versions 0.2.0 to 0.4.0, the z/OS atoe print functions use a constant length buffer for string conversion. If the input format string and arguments exceed the buffer size, a buffer overflow occurs. The vulnerability was resolved in version 0.5.0, where the conversion buffers are now correctly sized and checked.
The CVSS 4.0 score of 7.1 indicates a high severity level, with low attack complexity and no privileges required for exploitation. The vulnerability impacts confidentiality, integrity, and availability, with high impacts noted in both integrity and availability.
The affected products include Eclipse OMR, with the specific vulnerable versions ranging from 0.2.0 to 0.4.0. Organizations using these versions should take immediate action to update.
Technical Analysis
The root cause of this vulnerability stems from the improper handling of buffer sizes in the affected versions of Eclipse OMR. The use of a constant length buffer for string conversions fails to account for larger input sizes, leading to potential buffer overflow scenarios.
The attack vector is classified as local, indicating that an attacker must have local access to exploit the vulnerability. The attack complexity is low, meaning that it does not require specialized knowledge or conditions to carry out. Furthermore, there are no privileges required, and user interaction is not necessary.
The impacts of a successful exploitation are significant, with potential high integrity and availability impacts. Confidentiality impact is classified as low, indicating that data exposure is not the primary concern, but rather the potential disruption to services.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is substantial, particularly for organizations relying on Eclipse OMR for critical operations. The potential for service disruption due to buffer overflow could result in significant operational costs and reputational damage.
Organizations should be aware of the blast radius potential, as the vulnerability can affect any instance of the software where the affected versions are deployed. The urgency assessment is high, given the CVSS score of 7.1 and the fact that it is not included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that while there may not be active exploitation, the risk remains.

Affected Versions
The affected versions of Eclipse OMR are versions 0.2.0 to 0.4.0. Organizations using these versions should aim to upgrade to version 0.5.0 or later, where the issue has been resolved.
Mitigation & Remediation
To mitigate this vulnerability, it is crucial that organizations apply the latest patches provided by Eclipse. Specifically, upgrading to version 0.5.0 or higher will resolve the buffer overflow issue. Organizations should also consider implementing workarounds, such as restricting access to affected functionalities until the upgrade is completed.
In addition to patching, organizations may also benefit from conducting a thorough security assessment to identify any residual vulnerabilities within their systems. For ongoing security, organizations should consider engaging in penetration testing to validate their security posture regularly.
Detection Guidance
Organizations should monitor logs for any unusual patterns or anomalies that could indicate attempts to exploit this vulnerability. Additionally, security teams should be vigilant for any changes in system performance or integrity that could signal an ongoing attack.
Network signatures can also help identify potential exploit attempts against this vulnerability, allowing for faster incident response and remediation.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2025-1471 highlights the importance of rigorous buffer management practices in software development. The vulnerability represents a common yet critical oversight that can lead to severe exploitation opportunities if left unaddressed.
This incident serves as a reminder for security teams to enforce strict coding standards and conduct regular code reviews to prevent similar vulnerabilities from emerging. Organizations should also consider adopting a comprehensive vulnerability management program to systematically address vulnerabilities across all systems.
Finally, the strategic takeaway is to remain proactive in vulnerability assessment and penetration testing to ensure that organizations can quickly identify and mitigate potential threats. Continuous improvement of security practices will help mitigate risks associated with similar vulnerabilities in the future.
