CVE-2022-29063
Published: 02 September 2022
Summary
CVE-2022-29063 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Apache Ofbiz. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 4.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a deserialization flaw (CWE-502) in the Solr plugin of Apache OFBiz versions 18.12.05 and earlier. By default the plugin issues an RMI request to localhost on port 1099 at startup or restart; an attacker who can place a malicious RMI server on that interface can trigger arbitrary code execution.
An unauthenticated attacker with the ability to host a malicious RMI registry on the target host’s localhost interface can exploit the behavior simply by causing the OFBiz instance to start or restart. Successful exploitation yields remote code execution with the privileges of the OFBiz process, corresponding to the observed CVSS 9.8 rating.
Public advisories from the Apache OFBiz project and oss-security lists recommend upgrading to version 18.12.06 or later; the project also published patches addressing the issue under OFBIZ-12646.
The associated EPSS score has remained flat at 0.2083 with no material post-disclosure rise.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
