Improper Input Validation vulnerability in Apache Software Foundation Apache Airflow Apache…
CVE-2023-37415 is a high-severity improper input validation vulnerability in Apache Airflow Apache Hive Provider from Apache, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 6.1.2 as the first without the flaw, so updating Apache Airflow Apache Hive Provider to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.59% chance of exploitation within 30 days, higher than 76% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Apache Airflow Apache Hive Provider to 6.1.2 or a later version.
- Update apache-airflow-providers-apache-hive to 6.1.2 or a later version.
- Read the advisory on lists.apache.org for workarounds and exact fixed builds.

The underlying weakness: Improper Input Validation
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
How developers prevent this class of flaw
- Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build recognizers for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of allowing parser code to be scattered throughout the program, where it could be subject to errors or inconsistencies that create weaknesses.
- Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
- Understand all the potential areas where untrusted inputs can enter the product, including but not limited to: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
