Overview<\/strong><\/p>\n

This report discusses a significant cybersecurity vulnerability identified as CVE-2025-27578, primarily affecting Pixmeo OsiriX MD, a popular medical imaging software. This vulnerability is of critical importance due to its potential to cause system compromise and data leakage, leading to severe damage to both system integrity and confidentiality.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-27578
\nSeverity: High (CVSS: 7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Pixmeo OsiriX MD | All versions prior to the patched version<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the management of DICOM files, a standard for transmitting, storing, retrieving, and sharing medical images. 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

Conceptual Example Code<\/strong><\/p>\n

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

POST \/upload\/dicom HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/dicom\n{ \"dicom_file\": \"BASE64_ENCODED_MALICIOUS_DICOM_FILE_CONTENTS\" }<\/code><\/pre>\n
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
Mitigation Guidance<\/strong><\/p>\n
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":"
