"The version of Pulse Connect Secure installed on the remote host is prior to 22.7R2.3. It is, therefore, affected by
multiple vulnerabilities as referenced in the 000096001 advisory.

  - An out of bounds read in Ivanti Connect Secure before version 22.7R2.3 allows a remote unauthenticated
    attacker to trigger an infinite loop, causing a denial of service. (CVE-2024-37400)

  - A use-after-free in Ivanti Connect Secure before version 22.7R2.3 and Ivanti Policy Secure before version
    22.7R1.2 allows a remote authenticated attacker to achieve remote code execution. (CVE-2024-9420)

  - Excessive binary privileges in Ivanti Connect Secure which affects versions 22.4R2 through 22.7R2.2
    inclusive within the R2 release line and Ivanti Policy Secure before version 22.7R1.2 allow a local
    authenticated attacker to escalate privileges. (CVE-2024-47906)

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