CVE-2023-34297
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on systems running vulnerable versions of Sante DICOM Viewer Pro by tricking users into opening malicious JP2 image files. The flaw exists in how the software parses JP2 files without proper bounds checking, enabling out-of-bounds writes that can lead to remote code execution. Users of Sante DICOM Viewer Pro are affected when they open untrusted JP2 files.
💻 Affected Systems
- Sante DICOM Viewer Pro
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the affected system, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Attacker executes arbitrary code with the privileges of the current user, potentially installing malware, stealing sensitive medical data, or using the system as a foothold for further attacks.
If Mitigated
If proper controls like application sandboxing and least privilege are implemented, impact is limited to the application context with minimal system-wide damage.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) but no authentication. The vulnerability is in a file parser, making exploitation more complex than simple buffer overflows.
