Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Blind Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-20371)

The vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can trick the victim into initiating a request from their browser and force the application to initiate REST API calls on behalf of an authenticated high-privileged user.

Successful exploitation of this vulnerability requires that the "enableSplunkWebClientNetloc" setting in the web.conf configuration file to have a value of "true".


2) Resource exhaustion (CVE-ID: CVE-2025-20370)

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when processing LDAP bind requests. A remote privileged user with "change_authentication" capability can initiate multiple LDAP bind requests to a specific internal endpoint and perform a denial of service (DoS) attack.


3) XML External Entity injection (CVE-ID: CVE-2025-20369)

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input passed through Dashboard label field. A remote user can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.


4) Stored cross-site scripting (CVE-ID: CVE-2025-20368)

The disclosed vulnerability allows a remote user to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote user can inject a malicious payload through the error messages and job inspection details of a saved search and execute arbitrary HTML and script code in user's browser in context of vulnerable website.


5) Reflected cross-site scripting (CVE-ID: CVE-2025-20367)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in "/app/search/table" endpoint. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


6) Improper access control (CVE-ID: CVE-2025-20366)

The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote user can access sensitive search results if Splunk Enterprise runs an administrative search job in the background.
