Source: CVE
Vendor/Project: NIKON
Product: NIS-Elements Viewer

Description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NIKON NIS-Elements Viewer 1.2100.1483.0. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of TIF images. Crafted data in a TIF image can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15697.

Technical Analysis

CVE-2022-40663 is a high-severity vulnerability identified in NIKON's NIS-Elements Viewer version 1.2100.1483.0. The flaw is classified as CWE-125, an out-of-bounds read, which occurs specifically during the parsing of TIF image files. When the application processes a crafted TIF image containing maliciously structured data, it triggers a read operation beyond the allocated buffer boundaries. This memory corruption can be exploited by remote attackers to execute arbitrary code within the context of the current process. Exploitation requires user interaction, such as opening a malicious TIF file or visiting a web page that delivers such a file. The vulnerability does not require prior authentication or elevated privileges, but the user must actively engage with the malicious content. The CVSS v3.0 score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction. No known public exploits have been reported in the wild to date. The vulnerability was reported by the Zero Day Initiative (ZDI) and is publicly documented since September 2022. The lack of available patches at the time of reporting increases the risk for affected users. NIS-Elements Viewer is specialized software used primarily in scientific and industrial imaging contexts, often in research institutions and laboratories, where TIF images are common. The vulnerability's root cause lies in insufficient bounds checking during image parsing, a critical failure that can lead to memory corruption and code execution.

Potential Impact

For European organizations, particularly those in scientific research, healthcare, industrial imaging, and academic institutions, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, potentially allowing attackers to compromise sensitive research data, intellectual property, or patient information. The high impact on confidentiality, integrity, and availability means attackers could exfiltrate data, alter results, or disrupt operations. Since the vulnerability requires user interaction, phishing campaigns or malicious file distribution could be effective attack vectors. The absence of known exploits in the wild reduces immediate risk but does not eliminate it, especially as threat actors often develop exploits post-disclosure. Organizations relying on NIS-Elements Viewer for critical imaging workflows may face operational disruptions if exploited. Additionally, compromised systems could serve as footholds for lateral movement within networks, escalating the threat to broader organizational infrastructure.

Mitigation Recommendations

1. Immediate mitigation should focus on user awareness and training to avoid opening unsolicited or suspicious TIF files and visiting untrusted web pages. 2. Implement strict email and web filtering to block or quarantine TIF files from unknown or untrusted sources. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of NIS-Elements Viewer, reducing the impact of potential exploitation. 4. Monitor network and host behavior for anomalies indicative of exploitation attempts, such as unexpected process launches or memory access violations related to the viewer. 5. Since no official patches are currently available, consider isolating systems running NIS-Elements Viewer from critical network segments to limit exposure. 6. Engage with Nikon or authorized vendors to obtain updates or patches as soon as they are released. 7. Review and harden endpoint protection solutions to detect and prevent exploitation attempts targeting this vulnerability. 8. Maintain regular backups of critical data to enable recovery in case of compromise.
