Overview<\/strong><\/p>\n

The cybersecurity landscape is constantly evolving, with new vulnerabilities being discovered and patched on a regular basis. One such vulnerability, CVE-2025-20229, has been identified in certain versions of Splunk Enterprise and Splunk Cloud Platform. This vulnerability allows a low-privileged user to perform a Remote Code Execution (RCE) exploit, potentially compromising systems or leading to data<\/a> leakage.
\nSplunk, a widely used platform for searching, monitoring, and examining machine-generated big data, is an attractive target for cybercriminals due to its extensive use in both small and large organizations. This vulnerability is particularly dangerous because it allows unauthorized users to execute arbitrary code<\/a> on the system, potentially compromising the integrity, availability, and confidentiality of the system.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-20229
\nSeverity: High (CVSS: 8.0)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System Compromise, Potential Data Leakage<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Splunk Enterprise | Versions below 9.3.3, 9.2.5, and 9.1.8
\nSplunk Cloud Platform<\/a> | Versions below 9.3.2408.104, 9.2.2406.108, 9.2.2403.114, and 9.1.2312.208<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability exists due to insufficient authorization checks in the file<\/a> upload functionality of Splunk. Specifically, the file upload<\/a> to the “$SPLUNK_HOME\/var\/run\/splunk\/apptemp” directory does not properly validate the user’s permission level. Therefore, a low-privileged user, who does not hold the “admin” or “power” Splunk roles, can exploit this vulnerability by uploading a malicious file which can be executed<\/a> on the server, leading to Remote Code Execution (RCE).<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how the vulnerability might be exploited<\/a>. This example assumes that the attacker has valid credentials for a low-privileged user and is using a crafted file to exploit the vulnerability<\/a>:<\/p>\n

$ curl -X POST -u low_priv_user:password -F 'file=@malicious_file' 'http:\/\/target.splunk.com:8000\/en-US\/splunk\/var\/run\/splunk\/apptemp'<\/code><\/pre>\n
In this example, `low_priv_user:password` are the credentials of the low-privileged user, `malicious_file` is the file containing the malicious code<\/a>, and `target.splunk.com:8000` is the target Splunk server.<\/p>\n","protected":false},"excerpt":{"rendered":"
