Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.15% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Splunk Splunk Enterprise and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Manual assessmentRemediation target: Manual assessment

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

Improper Neutralization. Splunk addressed multiple internally identified vulnerabilities in Splunk Enterprise versions 10.4.3, 10.2.7, 10.0.10, and 9.4.15. The vulnerabilities are grouped by Common Weakness Enumeration (CWE), with one Common Vulnerabilities and Exposures (CVE) identifier assigned to each group. See Details for more information.

What

Improper Neutralization. Splunk addressed multiple internally identified vulnerabilities in Splunk Enterprise versions 10.4.3, 10.2.7, 10.0.10, and 9.4.15. The vulnerabilities are grouped by Common Weakness Enumeration (CWE), with one Common Vulnerabilities and Exposures (CVE) identifier assigned to each group. See Details for more information.

Why

The product does not ensure or incorrectly ensures that structured messages or data are well-formed and that certain security properties are met before being read from an upstream component or sent to a downstream component.

How

An attacker operating through the affected interface may attempt exploitation when the stated preconditions are met. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
