Security readout for executives and security teams
Plain-English summary
CVE-2020-11112 is a high-severity Jackson databind deserialization issue. In affected 2.x versions before 2.9.10.4, certain typing behavior can interact badly with a serialization gadget from apache/commons-proxy. If reachable in an application, impact could include confidentiality, integrity, and availability compromise.
Executive priority
Treat as a high-priority dependency remediation item for Java estates, especially exposed services. It is not confirmed actively exploited in the provided sources, but the potential impact is broad enough to justify prompt inventory and patch tracking.
Technical view
The issue is classified as CWE-502 and has CVSS 3.1 score 8.8: network attack vector, low complexity, no privileges, user interaction required, and high CIA impact. The named gadget is org.apache.commons.proxy.provider.remoting.RmiProvider, related to apache/commons-proxy.
Likely exposure
Likely exposure is Java software using FasterXML jackson-databind 2.x before 2.9.10.4, especially where the referenced commons-proxy class is present. The bundle does not provide CPEs or exact downstream affected versions, so dependency inventory is required.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Risk remains meaningful because the CVSS vector indicates remote reachability, low complexity, no privileges, and high potential impact when the vulnerable conditions exist.
Researcher notes
Evidence identifies the vulnerable component and gadget class but lacks precise CPEs, exploit status, and product-specific applicability. Validate exposure by dependency graph, runtime classpath, Jackson configuration, and downstream vendor advisories rather than assuming every Jackson use is exploitable.
Mitigation direction
- Upgrade jackson-databind to 2.9.10.4 or a vendor-supported fixed version.
- Check Debian, Oracle, NetApp, and application vendor advisories for packaged fixes.
- Inventory transitive jackson-databind and commons-proxy dependencies in Java applications.
- Review application typing/deserialization configuration against current Jackson guidance.
- Prioritize internet-facing or externally supplied data paths first.
Validation and detection
- Confirm deployed jackson-databind versions are not before 2.9.10.4.
- Check whether apache/commons-proxy is present in application classpaths.
- Identify services that deserialize externally supplied data with Jackson typing features.
- Review vendor product matrices for Oracle, NetApp, and OS package exposure.
- Verify remediation through dependency scans and runtime software inventory.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
