Arbitrary file write via unfiltered DB2 parameters
Published Aug 25, 2025 · Updated Aug 25, 2025
JNDI injection in FIT2CLOUD DataEase before 2.10.12 allows remote attackers to write arbitrary files through crafted DB2 parameters. Db2.getJdbc accepts an unfiltered RMI reference in either a supplied JDBC URL or assembled extraParams, letting JNDI invoke an AspectJWeaver deserialization gadget. The chain requires commons-collections 4.x and a vulnerable AspectJWeaver dependency, and its demonstrated consequence is file creation at attacker-chosen paths.
