high Nessus Plugin ID 172054

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5482-2 advisory.

 - 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)

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