Splunk recently patched several vulnerabilities in its Enterprise and Light products, including flaws that have been rated “high severity.”
Splunk Enterprise allows organizations to search, analyze and visualize data collected from websites, apps, sensors and other devices. Splunk Light is a solution that automates log searching and analysis, along with server and network monitoring, in small IT networks.
The most serious of the vulnerabilities affecting these products – with a CVSS score of 8.1 (high severity) – is CVE-2018-7427, a cross-site scripting (XSS) issue in the Splunk Web interface.
Another serious flaw allows an attacker to cause a denial-of-service (DoS) condition by sending a specially crafted HTTP request to Splunkd, the system process that handles indexing, searching and forwarding. This bug is tracked as CVE-2018-7429.
CVE-2018-7432 is a similar DoS flaw that can be exploited using malicious HTTP requests sent to Splunkd, but the vendor has only assigned it a “medium severity” rating.
The last vulnerability, tracked as CVE-2018-7431 and also rated “medium severity,” has been described as a path traversal issue that allows an authenticated attacker to download arbitrary files from the Splunk Django app.
Two of the vulnerabilities affect Splunk Enterprise versions 6.5.x before 6.5.3, 6.4.x before 6.4.7, 6.3.x before 6.3.10, 6.2.x before 6.2.14, 6.1.x before 6.1.13, 6.0.x before 6.0.14, and Splunk Light before 6.6.0. CVE-2018-7432 affects the same versions, except for 6.1.x and 6.0.x. CVE-2018-7429 impacts Enterprise 6.4.x before 6.4.8, 6.3.x before 6.3.11, 6.2.x before 6.2.14, and Light before 6.5.0.
Splunk says it has found no evidence to suggest that these vulnerabilities have been exploited for malicious purposes.
“To mitigate these issues, Splunk recommends upgrading to the latest release and applying as many of the Hardening Standards from the Securing Splunk documentation as are relevant to your environment. Splunk Enterprise and Splunk Light releases are cumulative, meaning that future releases will contain fixes to these vulnerabilities, new features and other bug fixes,” Splunk said in an advisory.
