"The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the SVD-2026-0210 advisory.

  - Issue summary: An application trying to decrypt CMS messages encrypted using password based encryption can
    trigger an out-of-bounds read and write. Impact summary: This out-of-bounds read may trigger a crash which
    leads to Denial of Service for an application. The out-of-bounds write can cause a memory corruption which
    can have various consequences including a Denial of Service or Execution of attacker-supplied code.
    Although the consequences of a successful exploit of this vulnerability could be severe, the probability
    that the attacker would be able to perform it is low. Besides, password based (PWRI) encryption support in
    CMS messages is very rarely used. For that reason the issue was assessed as Moderate severity according to
    our Security Policy. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue,
    as the CMS implementation is outside the OpenSSL FIPS module boundary. (CVE-2025-9230)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
