Recent updates from Splunk have addressed multiple vulnerabilities across its product suite, including two high-severity flaws in Splunk Enterprise and the Secure Gateway App. A critical remote code execution (RCE) vulnerability, identified as CVE-2025-20229 with a CVSS score of 8.0, was patched. This flaw, caused by a missing authorization check, could allow low-privileged users to execute arbitrary code by uploading files to a specific directory. The vulnerability has been mitigated in Splunk Enterprise versions 9.4.0, 9.3.3, 9.2.5, and 9.1.8, as well as in corresponding Splunk Cloud Platform versions.
Another significant issue involves an information disclosure vulnerability in both Splunk Enterprise and the Secure Gateway App, where user session and authorization tokens were exposed in clear text within log files. This flaw could be exploited through phishing attacks, potentially compromising user credentials. Patches for this vulnerability are available in Splunk Enterprise versions 9.4.1, 9.3.3, 9.2.5, and 9.1.8, and Secure Gateway versions 3.8.38 and 3.7.23.
Splunk has also released fixes for medium-severity vulnerabilities that could lead to unauthorized modifications and data manipulation within Splunk Enterprise. Additionally, low-severity issues in the Splunk App for Lookup Editing and various third-party packages have been addressed. While there are no reports of these vulnerabilities being exploited in the wild, users are strongly advised to update their systems promptly to mitigate potential risks.
The remote code execution vulnerability (CVE-2025-20229) in Splunk Enterprise poses a significant risk as it allows low-privileged users to execute arbitrary code on affected systems. This could lead to unauthorized access and control over critical infrastructure, potentially impacting thousands of systems globally.
The information disclosure flaw in the Splunk Secure Gateway App exposes sensitive user session data in log files, which could be leveraged in phishing attacks to gain unauthorized access to user accounts. This vulnerability affects industries relying on Splunk for monitoring and security operations, increasing the risk of data breaches.
