CVE-2023-3997: Splunk Soar

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

Splunk SOAR versions lower than 6.1.0 are indirectly affected by a potential vulnerability accessed through the user’s terminal. A third party can send Splunk SOAR a maliciously crafted web request containing special ANSI characters to cause log file poisoning. When a terminal user attempts to view the poisoned logs, this can tamper with the terminal and cause possible malicious code execution from the terminal user’s action.

Affected products

• Splunk Soar: before 6.1.0 (fixed in 6.1.0); before 6.1.0.131 (fixed in 6.1.0.131)
