SB2025061311 - Splunk Machine Learning Toolkit update for third-party components

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Incorrect Regular Expression (CVE-ID: CVE-2024-21538)

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

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

2) Cross-site scripting (CVE-ID: CVE-2024-11831)

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 passed via URL. 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.

3) Cross-site scripting (CVE-ID: CVE-2025-26791)

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

The vulnerability exists due to DOMPurify has an incorrect template literal regular expression. 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.

4) Infinite loop (CVE-ID: CVE-2024-55565)

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

The vulnerability exists due to infinite loop. A remote user can consume all available system resources and cause denial of service conditions.

5) Improper verification of cryptographic signature (CVE-ID: CVE-2024-48948)

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

The vulnerability exists due to incorrect validation of valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. Such behavior leads to valid signatures being rejected.

6) Inefficient regular expression complexity (CVE-ID: CVE-2025-27789)

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

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
