Vulnerability

Leica Biosystems reports limited product impact from Log4Shell

MedDevice Cyber Staff · Jan 7 · 2 min read · Via Leica Biosystems product security advisories

Leica Biosystems posted a Log4Shell notice on January 7, 2022 covering CVE-2021-44228 in the Apache Log4J logging software. Its summary says Leica Biosystems products have had limited impact from this vulnerability.

The index entry lists neither the products in that limited set nor the fix, so the linked detail page is where a lab confirms whether its pathology systems are among them. Log4j sat deep in Java dependencies across the sector, and a vendor statement is only as good as its product list.

For ProvidersOperators, hospitals, and clinical engineering

Leica Biosystems reports limited product impact from Log4Shell, CVE-2021-44228, without naming the products or a fix on its index. Pull the detail page and match it against your installed Leica Biosystems systems. Any listed product needs the vendor's remediation confirmed in writing.

Match the product list. Compare the Leica Biosystems Log4Shell detail against the systems installed in your lab.
Confirm remediation. For any listed system, get the applied fix or mitigation from Leica Biosystems support.
Scan for Log4j. Include Leica Biosystems servers in your own Log4j file scans so the vendor list is not the only check.

For Device ManufacturersAm I affected, and how to fix the class

Am I affected?

This class applies to devices with the signals and properties below. Check them against your product to gauge exposure.

Required

Off-the-shelf software

Fix the class in your product

The advisory is not for a bug you wrote; it is in a component you embed. As the maker, pin dependencies to fixed versions, generate an SBOM on every build including transitive components, and gate the pipeline on known-vulnerable components so an advisory maps to your products automatically.

Pin and inventory. Exact versions, and a CycloneDX or SPDX SBOM as a build artifact including transitive deps.
Gate on advisories. A CI scan fails a release carrying a component with a known advisory.
Own the field patch path. Know how you deliver a dependency or platform patch to fielded devices before you need it.
