CVSS 8.1 · High EPSS 0,44%
Kerentanan Improper Neutralization of Null Byte or NUL Character pada splunk. Skor CVSS 3.1 8.1 (High) menurut cisco.com.
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could affect system integrity and availability by sending a crafted Representational State Transfer (REST) API request that deletes or temporarily overwrites files writable by the user account running Splunk Enterprise processes on a non-captain search head cluster member. The vulnerability is possible because Search Head Clustering bundle replication does not validate the name of a replicated bundle file or neutralize NUL bytes before constructing the member bundle path.
