CVE-2026-44628: CWE-843 Access of resource using incompatible type ('type confusion') in OFFIS DICOM DCMTK Toolkit
An unauthenticated attacker can crash the worklist server with a single crafted query when the server has a valid Called AE Title / storage directory, the expected lockfile, and at least one matching worklist record.
AI Analysis
Technical Summary
This vulnerability involves a type confusion issue (CWE-843) in the OFFIS DICOM DCMTK Toolkit worklist server component. An attacker without authentication can trigger a crash by sending a crafted query when the server is configured with a valid Called AE Title, storage directory, the expected lockfile is present, and there is at least one matching worklist record. The flaw leads to access of a resource using an incompatible type, causing the server to crash and resulting in denial of service.
Potential Impact
Successful exploitation causes a denial of service by crashing the worklist server. This can disrupt medical imaging workflows that rely on the DCMTK Toolkit, potentially impacting availability of critical healthcare services. No evidence of code execution or data breach is provided.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented. Until a patch is available, consider restricting access to the worklist server to trusted networks and monitoring for anomalous queries that could trigger this condition.
