JDBC driver: Modification of Assumed-Immutable Data (MAID)
CVE-2024-55551 is a high-severity modification of assumed-immutable data (MAID) vulnerability in JDBC driver from Exasol, with a CVSS 3.1 base score of 8.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 24.2.1 as the first without the flaw, so updating JDBC driver to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.64% chance of exploitation within 30 days, higher than 51% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update JDBC driver to 24.2.1 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
Affected products and versions

Official description
An issue was discovered in Exasol JDBC driver before 24.2.1 (2024-12-10). Attackers can inject malicious parameters into the JDBC URL, triggering JNDI injection during the process when the JDBC Driver uses this URL to connect to the database. This can further lead to remote code execution.

The underlying weakness: Modification of Assumed-Immutable Data (MAID)
The product does not properly protect an assumed-immutable element from being modified by an attacker.
How developers prevent this class of flaw
- When the data is stored or transmitted through untrusted sources that could modify the data, implement integrity checks to detect unauthorized modification, or store/transmit the data in a trusted location that is free from external influence.
