An attacker can craft a malicious DICOM file and upload it to the affected system. The system, due to the use after free vulnerability, could then experience memory corruption, causing a denial-of-service condition.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3375028816\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here is a conceptual example of how the vulnerability might be exploited. This example merely illustrates the exploit and does not contain actual malicious code.<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/upload\/dicom HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/dicom\n{ &quot;dicom_file&quot;: &quot;BASE64_ENCODED_MALICIOUS_DICOM_FILE_CONTENTS&quot; }<\/code><\/pre>\n<p>In this example, the attacker sends a POST request to upload a crafted DICOM file. The malicious content within the DICOM file would trigger the use after free vulnerability, potentially leading to system compromise or data leakage.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>Users are advised to apply the vendor-provided patch immediately to mitigate the vulnerability. If the patch cannot be applied immediately, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these are not long-term solutions and the patch should be applied as soon as possible to effectively secure the system.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report discusses a significant cybersecurity vulnerability identified as CVE-2025-27578, primarily affecting Pixmeo OsiriX MD, a popular medical imaging software.
