CVE-2018-12022: An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6.

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Jodd-db jar (for database access for the Jodd framework) in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

Security readout for executives and security teams

Plain-English summary

This is a conditional remote code execution risk in Jackson Databind. A vulnerable Java service is exposed only when old Jackson versions are used, Default Typing is enabled, Jodd-db is on the classpath, and attacker-controlled input can cause outbound LDAP access.

Executive priority

Prioritize systems that process untrusted input in Java services. This is not automatically exploitable everywhere, but affected combinations can lead to code execution, making remediation important for internet-facing and high-trust services.

Technical view

CVE-2018-12022 affects jackson-databind before 2.7.9.4, 2.8.11.2, and 2.9.6. With Default Typing enabled and the Jodd-db jar present, unsafe polymorphic deserialization can allow execution of a malicious payload via attacker-provided LDAP interaction.

Likely exposure

Most likely exposure is Java applications or bundled products using vulnerable jackson-databind versions with Default Typing enabled and Jodd-db available at runtime. Dependency transitivity matters, so applications may be exposed even if Jackson is not directly declared.

Exploitation context

The source bundle says exploitation requires specific runtime conditions and attacker-controlled LDAP access. CISA KEV is false, and the provided sources do not state active exploitation. No exploit maturity or public weaponization evidence is provided here.

Researcher notes

Evidence is strongest for the vulnerable conditions and fixed version thresholds. The bundle does not include CVSS, CWE, exploit status, or a complete affected product list. Treat product exposure as dependency and runtime-configuration dependent.

Mitigation direction

  • Upgrade jackson-databind to a fixed or vendor-supported version.
  • Apply relevant Red Hat, Debian, or application vendor security updates.
  • Disable Default Typing where it is not strictly required.
  • Remove Jodd-db from runtime classpaths if unused.
  • Restrict outbound LDAP from application runtimes where feasible.
  • Check vendor guidance for affected packaged products.

Validation and detection

  • Inventory jackson-databind versions across direct and transitive dependencies.
  • Review code and configuration for enabled Default Typing.
  • Confirm whether Jodd-db is present in runtime classpaths.
  • Check whether exposed services deserialize attacker-controlled data.
  • Verify vendor package updates are installed in managed platforms.
