CVE-2022-24697: Apache Kylin vulnerable to remote code execution

Kylin's cube designer function has a command injection vulnerability when overwriting system parameters in the configuration overwrites menu. RCE can be implemented by closing the single quotation marks around the parameter value of “-- conf=” to inject any operating system command into the command line parameters. This vulnerability affects Kylin 2 version 2.6.5 and earlier, Kylin 3 version 3.1.2 and earlier, and Kylin 4 version 4.0.1 and earlier.

Root Cause Analysis

The vulnerability occurs during Spark command construction where user-supplied configuration parameters (--conf) are directly embedded into the command string. The advisory mentions command injection via breaking out of single quotes around '--conf' values, indicating improper neutralization during command string assembly. The affected packages (kylin-spark-project) and CWE-77 pattern both point to command-building functions in Spark job execution logic. The subsequent CVE-2022-43396 and its patch (PR #2011) confirm that the initial fix in PR #1811 was insufficient, reinforcing that the core vulnerability resides in how Spark commands are constructed with user input.
