CVE-2024-36996: Information Disclosure of user names

• Severity: medium (CVSS 5.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-07-01 · updated 2026-06-17
• Weakness: CWE-204

Description

In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.109, an attacker could determine whether or not another user exists on the instance by deciphering the error response that they would likely receive from the instance when they attempt to log in. This disclosure could then lead to additional brute-force password-guessing attacks. This vulnerability would require that the Splunk platform instance uses the Security Assertion Markup Language (SAML) authentication scheme.

Affected products

• Splunk Enterprise: from 9.0.0 through 9.0.10; from 9.1.0 before 9.1.5; from 9.2.0 before 9.2.2 — fixed in 9.1.5, 9.2.2
• Splunk Cloud Platform: from 9.1.2312 before 9.1.2312.109 — fixed in 9.1.2312.109

How to fix

Upgrade to a fixed version: Splunk Enterprise 9.1.5, 9.2.2; Splunk Cloud Platform 9.1.2312.109. Check the vendor advisory for mitigations.
