According to its self-reported version, the instance of SPIP CMS running on the remote web server is prior to 3.2.14 or 4.0.x prior to 4.0.5. It is, therefore, affected by multiples vulnerabilities : 
 - A Remote Code Execution
 - Unauthenticated access to information about editorial objects.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2949 advisory.

  - SPIP before 3.2.14 and 4.x before 4.0.5 allows remote authenticated editors to execute arbitrary code.
    (CVE-2022-26846)

  - SPIP before 3.2.14 and 4.x before 4.0.5 allows unauthenticated access to information about editorial     objects. (CVE-2022-26847)

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

The remote Ubuntu 18.04 LTS / 21.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5482-1 advisory.

  - prive/formulaires/configurer_preferences.php in SPIP before 3.2.8 does not properly validate the couleur,     display, display_navigation, display_outils, imessage, and spip_ecran parameters. (CVE-2020-28984)

  - SPIP 4.0.0 is affected by a Cross Site Scripting (XSS) vulnerability. To exploit the vulnerability, a     visitor must browse to a malicious SVG file. The vulnerability allows an authenticated attacker to inject     malicious code running on the client side into web pages visited by other users (stored XSS).
    (CVE-2021-44118)

  - SPIP 4.0.0 is affected by a Cross Site Scripting (XSS) vulnerability in ecrire/public/interfaces.php,     adding the function safehtml to the vulnerable fields. An editor is able to modify his personal     information. If the editor has an article written and available, when a user goes to the public site and     wants to read the author's information, the malicious code will be executed. The Who are you and     Website Name fields are vulnerable. (CVE-2021-44120)

  - SPIP 4.0.0 is affected by a Cross Site Request Forgery (CSRF) vulnerability in     ecrire/public/aiguiller.php, ecrire/public/balises.php, ecrire/balise/formulaire_.php. To exploit the     vulnerability, a visitor must visit a malicious website which redirects to the SPIP website. It is also     possible to combine XSS vulnerabilities in SPIP 4.0.0 to exploit it. The vulnerability allows an     authenticated attacker to execute malicious code without the knowledge of the user on the website (CSRF).
    (CVE-2021-44122)

  - SPIP 4.0.0 is affected by a remote command execution vulnerability. To exploit the vulnerability, an     attacker must craft a malicious picture with a double extension, upload it and then click on it to execute     it. (CVE-2021-44123)

  - SPIP before 3.2.14 and 4.x before 4.0.5 allows remote authenticated editors to execute arbitrary code.
    (CVE-2022-26846)

  - SPIP before 3.2.14 and 4.x before 4.0.5 allows unauthenticated access to information about editorial     objects. (CVE-2022-26847)

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