CVE-2024-49194 identifies a high-severity vulnerability found in the Databricks JDBC Driver, specifically versions prior to 2.6.40. This vulnerability allows potential remote code execution (RCE) by exploiting a JNDI injection through a JDBC URL parameter. The flaw originates from improper handling of the krbJAASFile parameter, which can be manipulated by an attacker. By crafting a malicious connection URL, an attacker could compromise the driver’s execution context, leading to unauthorized code execution.
The severity of this vulnerability is classified as high, with a CVSS score of 7.3. This rating indicates significant risk to organizations, particularly as the attack vector is network-based and the attack complexity is low. Attackers may leverage this vulnerability to gain unauthorized access and control over systems using the affected driver. Organizations should prioritize patching immediately to mitigate this risk and prevent potential exploitation.
Currently, there are no known public exploits or proofs of concept available for this vulnerability, indicating that while the risk is significant, it may not yet be actively exploited in the wild. However, the potential for exploitation remains a concern, and organizations using affected versions of the Databricks JDBC Driver should remain vigilant.
Given the nature of the vulnerability and its potential impact, it is critical for security teams to assess their environments for the use of the Databricks JDBC Driver. Organizations should ensure that they are using an updated version of the driver to guard against this vulnerability.
Vulnerability Details
The vulnerability allows remote code execution due to JNDI injection via a JDBC URL parameter. The improper handling of the krbJAASFile parameter enables an attacker to execute arbitrary code in the context of the JDBC driver. The CVSS score of 7.3 reflects the high impact on confidentiality and integrity, while availability is not affected.
Technical Analysis
The root cause of this vulnerability lies in the improper validation and handling of user-supplied input in the JDBC driver. An attacker can exploit this vulnerability by crafting a malicious JDBC URL that includes the krbJAASFile parameter. This can lead to remote code execution, as the driver executes the code without proper validation.
Risk & Impact Analysis
Organizations using the affected versions of the Databricks JDBC Driver face significant risks. The potential for remote code execution can lead to unauthorized system access, data breaches, and overall compromise of application integrity. Given the low attack complexity and the requirement for user interaction, the risk remains high. Organizations should assess their exposure and prioritize patching to mitigate this vulnerability effectively.

Affected Versions
Databricks JDBC Driver versions before 2.6.40 are affected. Organizations should ensure they are using the latest version to mitigate this vulnerability.
Mitigation & Remediation
Organizations should apply the latest patch for the Databricks JDBC Driver to remediate this vulnerability. In the absence of a patch, consider implementing network controls to limit access to the database and monitor for unusual activity. Additionally, organizations should review their JDBC connection configurations to ensure they do not utilize vulnerable parameters.
Detection Guidance
Monitor logs for unusual JDBC connection attempts that utilize the krbJAASFile parameter. Look for patterns of unexpected user interactions and implement alerts for such activities. Behavioral anomalies should also be investigated promptly.
