CVE-2023-34297 in DICOM Viewer Pro
Summary
by MITRE • 05/03/2024
Sante DICOM Viewer Pro JP2 File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sante DICOM Viewer Pro. 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 JP2 files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21127.

The CVE-2023-34297 vulnerability represents a critical out-of-bounds write flaw in Sante DICOM Viewer Pro's JP2 file parsing functionality, constituting a remote code execution vulnerability that poses significant operational risks to healthcare and medical imaging environments. This vulnerability specifically targets the processing of JPEG 2000 image files within the DICOM viewer application, where insufficient input validation leads to memory corruption during file parsing operations. The flaw exists in the software's handling of user-supplied JP2 file data, creating a scenario where maliciously crafted files can trigger memory corruption that allows arbitrary code execution in the context of the running application process.
The technical nature of this vulnerability aligns with CWE-787, which describes out-of-bounds write conditions where an attacker can write data past the end of allocated memory buffers. This particular implementation flaw occurs during the JP2 file parsing routine where the application fails to properly validate the structure and size of incoming data, allowing attackers to craft specially formatted JP2 files that trigger memory corruption. The vulnerability's remote exploitation capability means that attackers can deliver malicious payloads through web-based attacks or file sharing mechanisms without requiring local system access. The requirement for user interaction through visiting malicious web pages or opening malicious files aligns with ATT&CK technique T1203, which covers exploitation for execution through user interaction with malicious content.
The operational impact of this vulnerability extends beyond typical remote code execution scenarios due to the specialized nature of DICOM viewers in healthcare environments. Medical imaging systems often operate in sensitive environments where unauthorized code execution could compromise patient data integrity and system availability. The vulnerability affects Sante DICOM Viewer Pro specifically, which is commonly used in hospital and medical facility settings for viewing and managing medical imaging data, making it a prime target for attackers seeking to exploit healthcare infrastructure. The fact that this vulnerability allows code execution in the context of the current process means that successful exploitation could provide attackers with access to medical imaging data, potentially leading to data breaches or system compromise that affects patient care and regulatory compliance.
Mitigation strategies for CVE-2023-34297 should focus on immediate patch application from the vendor, as this vulnerability represents a high-severity risk that requires urgent attention. Organizations should implement network-based controls such as web application firewalls and content filtering to prevent access to known malicious content, while also monitoring for suspicious file downloads or web traffic patterns. The vulnerability's classification as a remote code execution flaw necessitates defensive measures including application whitelisting, privilege separation, and network segmentation to limit potential impact if exploitation occurs. Additionally, organizations should conduct thorough vulnerability assessments of their medical imaging infrastructure to identify other potential attack vectors and ensure that all systems handling medical data maintain appropriate security controls. The ZDI-CAN-21127 reference indicates this vulnerability was tracked by the Zero Day Initiative, highlighting its recognition as a significant security concern requiring immediate remediation.
