CVE-2024-39847: Arbitrary File Read and Server Side Request Forgery via XML External Entities in 4D Server SOAP
Unauthenticated attackers can exploit a weakness in the XML parser functionality of the SOAP endpoints in 4D server. This allows them to obtain read access to files on the application server and adjacent network shares, and perform HTTP GET requests to arbitrary services.
Security readout for executives and security teams
CVE-2024-39847 is a high-severity flaw in 4D Server SOAP handling. An unauthenticated attacker can abuse XML processing to read files from the server or nearby network shares and make the server send HTTP GET requests to other services. Exposure is most likely where 4D Server SOAP endpoints are reachable from untrusted networks or the internet. Systems with access to sensitive local files, mounted shares, or internal HTTP services face greater business risk. Treat as a near-term remediation item for any exposed 4D Server SOAP deployment. The main risk is sensitive data exposure and internal service probing without authentication. Prioritize internet-facing or high-trust network placements first. Mitigation focus: Check 4D and SCHUTZWERK guidance for fixed versions or configuration changes.; Restrict SOAP endpoints to trusted networks only.; Disable SOAP functionality if it is not required..

Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references file access or upload behavior, so file telemetry and web shell review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Restriction of XML External Entity Reference
Improper Restriction of XML External Entity Reference represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
