CVE-2019-0193
RCE in Apache Solr ≤ 7.7.3
Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2019-0193 is a high-severity Code Injection (CWE-94) vulnerability in Apache Solr. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
In Apache Solr, the optional DataImportHandler module used to ingest data from databases and other sources contains a vulnerability that permits the full DIH configuration, including executable scripts, to be supplied through the "dataConfig" request parameter. This capability is exposed in the debug mode of the DIH admin screen for development convenience and is tracked under CWE-94. The issue affects Solr instances prior to version 8.2.0 where the parameter is enabled by default.
An attacker with administrative access to the DIH interface can submit a crafted request containing malicious script content in the dataConfig parameter, leading to remote code execution or other high-impact actions on the server. The CVSS 7.2 score reflects network attack vector, low complexity, and high confidentiality, integrity, and availability consequences when privileges are held.
Advisories and release notes indicate that Solr 8.2.0 and later disable the parameter by default; operators must explicitly set the Java system property "enable.dih.dataConfigParam" to true if the debug feature is required. The referenced Apache JIRA issue and mailing list threads document this change and the associated security rationale.

Vulnerability Data
In Apache Solr, the DataImportHandler, an optional but popular module to pull in data from databases and other sources, has a feature in which the whole DIH configuration can come from a request's "dataConfig" parameter. The debug mode of the…

DIH admin screen uses this to allow convenient debugging / development of a DIH config. Since a DIH config can contain scripts, this parameter is a security risk. Starting with version 8.2.0 of Solr, use of this parameter requires setting the Java System property "enable.dih.dataConfigParam" to true.

Likely Mitigating Controls AI
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.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
