CVE-2025-9274 is a high-severity vulnerability affecting Oxford Instruments Imaris Viewer version 10.0.1. The flaw arises from improper handling of IMS file parsing, specifically due to the access of an uninitialized pointer (CWE-824). When the software processes IMS files, it fails to properly initialize a pointer before accessing it, which can lead to undefined behavior. An attacker can craft a malicious IMS file or host a malicious page that, when opened or visited by a user running the vulnerable Imaris Viewer, triggers this flaw. Exploitation allows remote code execution (RCE) within the context of the current process, enabling the attacker to execute arbitrary code. The vulnerability requires user interaction, such as opening a malicious file or visiting a malicious webpage. The CVSS v3.0 score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. Although no known exploits are currently in the wild, the vulnerability poses a significant risk due to the potential for full system compromise through crafted IMS files. The vulnerability was publicly disclosed on September 2, 2025, and was assigned by the Zero Day Initiative (ZDI) under identifier ZDI-CAN-21657. No patches have been linked yet, indicating that affected users should exercise caution and monitor for updates from Oxford Instruments.

For European organizations using Oxford Instruments Imaris Viewer, particularly in scientific research, medical imaging, and industrial applications, this vulnerability could lead to severe consequences. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to data theft, manipulation of research data, disruption of critical imaging workflows, or deployment of malware within sensitive environments. Given that Imaris Viewer is used for advanced visualization and analysis of microscopy data, compromised systems could affect research integrity and intellectual property protection. The requirement for user interaction means phishing or social engineering could be vectors, increasing risk in environments with less stringent user awareness. Additionally, the high confidentiality and integrity impact could affect compliance with European data protection regulations such as GDPR if sensitive data is exposed or altered. The availability impact could disrupt scientific operations, delaying research and diagnostics. Overall, the vulnerability poses a significant operational and reputational risk to European organizations relying on this software.

1. Immediate mitigation should include restricting the opening of IMS files from untrusted or unknown sources until a patch is available. 2. Implement strict user training and awareness programs to recognize phishing attempts or suspicious files related to Imaris Viewer. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of Imaris Viewer, reducing the impact of potential exploitation. 4. Monitor network traffic and endpoint behavior for anomalies indicative of exploitation attempts, such as unexpected process spawning or memory access violations. 5. Coordinate with Oxford Instruments for timely patch deployment once available and prioritize updating affected systems. 6. Consider isolating systems running Imaris Viewer from critical networks or sensitive data repositories to limit lateral movement in case of compromise. 7. Use endpoint detection and response (EDR) tools to detect and respond to suspicious activities related to this vulnerability. 8. Maintain regular backups of critical data to enable recovery in case of compromise.
