In Apache Linkis versions 1.4.0 and earlier, a vulnerability exists that exposes sensitive information. Specifically, when using the Oracle data source of the Linkis data source module, the password is printed to the log. This can lead to unauthorized access if the logs are not properly secured. The CVSS score for this vulnerability is 5.3, indicating a medium severity level, which is significant enough to warrant immediate attention from organizations utilizing this software.
Organizations should prioritize patching immediately. The recommended action is to upgrade to Apache Linkis version 1.5.0, which addresses this logging issue. The exposure of sensitive information through logs can lead to serious consequences, including unauthorized access and data breaches.
Currently, there are no known exploits for this vulnerability, as indicated by both the exploitability and known exploitation statuses. However, the potential for abuse exists, making timely remediation essential. Organizations should assess their logging practices and ensure that sensitive information is not being unnecessarily exposed.
The urgency for defenders is clear. As this vulnerability has been classified as medium severity, it is crucial to integrate the necessary patches into the next patch cycle and ensure robust logging security measures are in place to prevent this type of exposure in the future.
Vulnerability Details
The official description of CVE-2023-50740 states: 'In Apache Linkis <=1.4.0, the password is printed to the log when using the Oracle data source of the Linkis data source module.' This vulnerability has a CVSS score of 5.3, which signifies medium severity. It affects all versions of Linkis prior to 1.5.0, and is classified under CWE-532, which pertains to improper exposure of sensitive information.
This vulnerability was published on March 6, 2024, highlighting the importance of maintaining updated systems to mitigate risks associated with known vulnerabilities.
Technical Analysis
The root cause of CVE-2023-50740 lies in the improper logging of sensitive data, specifically the password for Oracle data sources within the Linkis system. The attack vector for this vulnerability is network-based, with low complexity, meaning that an attacker does not require elevated privileges or user interaction to exploit the vulnerability. The confidentiality impact is categorized as low, as the password exposure can be mitigated through secure log management practices.
In terms of the attack complexity, it is rated as low, indicating that the vulnerability can be exploited with minimal effort. The integrity and availability impacts are both negligible, as the primary concern is unauthorized access resulting from exposed credentials.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive systems and data due to credential exposure through logging. The blast radius for this vulnerability could be significant if an attacker gains access to the logs, as they may obtain critical passwords that could compromise entire data sources. Organizations relying on Apache Linkis for data management must understand the implications of this vulnerability and take immediate action to upgrade to version 1.5.0.
The urgency assessment is classified as medium. Therefore, organizations should schedule remediation efforts to ensure all affected systems are updated and secure against similar vulnerabilities in the future.
