CISA KEV Advisory
Apache Solr DataImportHandler Code Injection Vulnerability
The optional Apache Solr module DataImportHandler contains a code injection vulnerability.
Apply updates per vendor instructions.
Risk Analysis
This code injection vulnerability in the optional DataImportHandler module of Apache Solr allows attackers to inject and execute malicious code. The high EPSS score of 0.93202 indicates a strong likelihood of exploitation, and its presence in CISA's KEV confirms it is being actively exploited.
This vulnerability is actively exploited in the wild and is part of CISA's Known Exploited Vulnerabilities Catalog. Attackers are leveraging this flaw for code injection.
Update Apache Solr to a patched version. If the DataImportHandler module is not essential, consider disabling or removing it to reduce the attack surface.
Technical Analysis
CVE-2019-0193 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2019-0193 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
