Fixing Splunk Vulnerability with New Updates
Source: SplunkThis vulnerability affects versions prior to 9.0.10, 9.1.5, and 9.2.2. Attackers exploiting this flaw can execute arbitrary commands by leveraging the “copybuckets.py” script within the “splunk_archiver” application. This issue highlights the importance of upgrading to the latest Splunk versions promptly or temporarily disabling the affected application to mitigate risks.
Another significant vulnerability, CVE-2024-36984, allows authenticated users in Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 on Windows to execute arbitrary code through a serialized session payload. This exploit occurs when untrusted data is serialized via the collect SPL command, enabling attackers to execute malicious code within the payload.
“Splunk rates this vulnerability as 8.8, High, with a CVSSv3.1 vector of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. If the Splunk Enterprise instance disabled splunk_archiver, there is no impact and the severity is Informational”, says Splunk.
Comprehensive Security Measures and Recommendations
Splunk has advised users to update their installations to the latest versions to protect against these vulnerabilities effectively. Additionally, mitigating actions such as disabling the “splunk_archiver” application can provide interim protection until updates can be applied.
