Zabbix before 5.0 represents passwords in the users table with unsalted MD5.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Zabbix before 5.0 represents passwords in the users table with unsalted MD5. (CVE-2013-7484)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3538 advisory.

  - Zabbix before 5.0 represents passwords in the users table with unsalted MD5. (CVE-2013-7484)

  - An issue was discovered in zabbix.php?action=dashboard.view&dashboardid=1 in Zabbix through 4.4. An     attacker can bypass the login page and access the dashboard page, and then create a Dashboard, Report,     Screen, or Map without any Username/Password (i.e., anonymously). All created elements     (Dashboard/Report/Screen/Map) are accessible by other users and by an admin. (CVE-2019-17382)

  - Zabbix Frontend provides a feature that allows admins to maintain the installation and ensure that only     certain IP addresses can access it. In this way, any user will not be able to access the Zabbix Frontend     while it is being maintained and possible sensitive data will be prevented from being disclosed. An     attacker can bypass this protection and access the instance using IP address not listed in the defined     range. (CVE-2022-43515)

  - JavaScript pre-processing can be used by the attacker to gain access to the file system (read-only access     on behalf of user zabbix) on the Zabbix Server or Zabbix Proxy, potentially leading to unauthorized     access to sensitive data. (CVE-2023-29450)

  - Specially crafted string can cause a buffer overrun in the JSON parser library leading to a crash of the     Zabbix Server or a Zabbix Proxy. (CVE-2023-29451)

  - Stored or persistent cross-site scripting (XSS) is a type of XSS where the attacker first sends the     payload to the web application, then the application saves the payload (e.g., in a database or server-side     text files), and finally, the application unintentionally executes the payload for every victim visiting     its web pages. (CVE-2023-29454)

  - Reflected XSS attacks, also known as non-persistent attacks, occur when a malicious script is reflected     off a web application to the victim's browser. The script is activated through a link, which sends a     request to a website with a vulnerability that enables execution of malicious scripts. (CVE-2023-29455)

  - URL validation scheme receives input from a user and then parses it to identify its various components.
    The validation scheme can ensure that all URL components comply with internet standards. (CVE-2023-29456)

  - Reflected XSS attacks, occur when a malicious script is reflected off a web application to the victim's     browser. The script can be activated through Action form fields, which can be sent as request to a website     with a vulnerability that enables execution of malicious scripts. (CVE-2023-29457)

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

This update for zabbix fixes the following issues :

CVE-2021-27927: Fixed an improper CSRF protection mechanism (bsc#1183014).

CVE-2013-7484: Fixed an issue where passwords in the users table were unsalted (bsc#1158321).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
