"The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the
dla-3765 advisory.

  - Cacti is an open source operational monitoring and fault management framework. A defect in the sql_save
    function was discovered. When the column type is numeric, the sql_save function directly utilizes user
    input. Many files and functions calling the sql_save function do not perform prior validation of user
    input, leading to the existence of multiple SQL injection vulnerabilities in Cacti. This allows
    authenticated users to exploit these SQL injection vulnerabilities to perform privilege escalation and
    remote code execution. This issue has been addressed in version 1.2.25. Users are advised to upgrade.
    There are no known workarounds for this vulnerability. (CVE-2023-39357)

  - Cacti is an open source operational monitoring and fault management framework.Affected versions are
    subject to a Stored Cross-Site-Scripting (XSS) Vulnerability allows an authenticated user to poison data.
    The vulnerability is found in `graphs_new.php`. Several validations are performed, but the `returnto`
    parameter is directly passed to `form_save_button`. In order to bypass this validation, returnto must
    contain `host.php`. This vulnerability has been addressed in version 1.2.25. Users are advised to upgrade.
    Users unable to update should manually filter HTML output. (CVE-2023-39360)

  - Cacti is an open source operational monitoring and fault management framework. Affected versions are
    subject to a SQL injection discovered in graph_view.php. Since guest users can access graph_view.php
    without authentication by default, if guest users are being utilized in an enabled state, there could be
    the potential for significant damage. Attackers may exploit this vulnerability, and there may be
    possibilities for actions such as the usurpation of administrative privileges or remote code execution.
    This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known
    workarounds for this vulnerability. (CVE-2023-39361)

  - Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, under
    certain conditions, an authenticated privileged user, can use a malicious string in the SNMP options of a
    Device, performing command injection and obtaining remote code execution on the underlying server. The
    `lib/snmp.php` file has a set of functions, with similar behavior, that accept in input some variables and
    place them into an `exec` call without a proper escape or validation. This issue has been addressed in
    version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.
    (CVE-2023-39362)

  - Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, users with
    console access can be redirected to an arbitrary website after a change password performed via a
    specifically crafted URL. The `auth_changepassword.php` file accepts `ref` as a URL parameter and reflects
    it in the form used to perform the change password. It's value is used to perform a redirect via `header`
    PHP function. A user can be tricked in performing the change password operation, e.g., via a phishing
    message, and then interacting with the malicious website where the redirection has been performed, e.g.,
    downloading malwares, providing credentials, etc. This issue has been addressed in version 1.2.25. Users
    are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-39364)

  - Cacti is an open source operational monitoring and fault management framework. Issues with Cacti Regular
    Expression validation combined with the external links feature can lead to limited SQL Injections and
    subsequent data leakage. This issue has been addressed in version 1.2.25. Users are advised to upgrade.
    There are no known workarounds for this vulnerability. (CVE-2023-39365)

  - Cacti is an open source operational monitoring and fault management framework. Affected versions are
    subject to a Stored Cross-Site-Scripting (XSS) Vulnerability which allows an authenticated user to poison
    data stored in the _cacti_'s database. These data will be viewed by administrative _cacti_ accounts and
    execute JavaScript code in the victim's browser at view-time. The script under `host.php` is used to
    monitor and manage hosts in the _cacti_ app, hence displays useful information such as data queries and
    verbose logs. _CENSUS_ found that an adversary that is able to configure a data-query template with
    malicious code appended in the template path, in order to deploy a stored XSS attack against any user with
    the _General Administration>Sites/Devices/Data_ privileges. A user that possesses the _Template
    Editor>Data Queries_ permissions can configure the data query template path in _cacti_. Please note that
    such a user may be a low privileged user. This configuration occurs through
    `http://<HOST>/cacti/data_queries.php` by editing an existing or adding a new data query template. If a
    template is linked to a device then the formatted template path will be rendered in the device's
    management page, when a _verbose data query_ is requested. This vulnerability has been addressed in
    version 1.2.25. Users are advised to upgrade. Users unable to update should manually filter HTML output.
    (CVE-2023-39513)

  - Cacti is an open source operational monitoring and fault management framework. Affected versions are
    subject to a Stored Cross-Site-Scripting (XSS) Vulnerability allows an authenticated user to poison data
    stored in the cacti's database. These data will be viewed by administrative cacti accounts and execute
    JavaScript code in the victim's browser at view-time. The script under `data_debug.php` displays data
    source related debugging information such as _data source paths, polling settings, meta-data on the data
    source_. _CENSUS_ found that an adversary that is able to configure a malicious data-source path, can
    deploy a stored XSS attack against any user that has privileges related to viewing the `data_debug.php`
    information. A user that possesses the _General Administration>Sites/Devices/Data_ permissions can
    configure the data source path in _cacti_. This configuration occurs through
    `http://<HOST>/cacti/data_sources.php`. This vulnerability has been addressed in version 1.2.25. Users are
    advised to upgrade. Users unable to update should manually filter HTML output. (CVE-2023-39515)

  - Cacti is an open source operational monitoring and fault management framework. Affected versions are
    subject to a Stored Cross-Site-Scripting (XSS) Vulnerability which allows an authenticated user to poison
    data stored in the _cacti_'s database. These data will be viewed by administrative _cacti_ accounts and
    execute JavaScript code in the victim's browser at view-time. The script under `data_sources.php` displays
    the data source management information (e.g. data source path, polling configuration etc.) for different
    data visualizations of the _cacti_ app. CENSUS found that an adversary that is able to configure a
    malicious data-source path, can deploy a stored XSS attack against any user of the same (or broader)
    privileges. A user that possesses the 'General Administration>Sites/Devices/Data' permissions can
    configure the data source path in Cacti. This configuration occurs through
    `http://<HOST>/cacti/data_sources.php`. The same page can be used for previewing the data source path.
    This issue has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to upgrade
    should manually escape HTML output. (CVE-2023-39516)

  - Cacti is a robust performance and fault management framework and a frontend to RRDTool - a Time Series
    Database (TSDB). While using the detected SQL Injection and insufficient processing of the include file
    path, it is possible to execute arbitrary code on the server. Exploitation of the vulnerability is
    possible for an authorized user. The vulnerable component is the `link.php`. Impact of the vulnerability
    execution of arbitrary code on the server. (CVE-2023-49084)

  - Cacti provides an operational monitoring and fault management framework. In versions 1.2.25 and prior, it
    is possible to execute arbitrary SQL code through the `pollers.php` script. An authorized user may be able
    to execute arbitrary SQL code. The vulnerable component is the `pollers.php`. Impact of the vulnerability
    - arbitrary SQL code execution. As of time of publication, a patch does not appear to exist.
    (CVE-2023-49085)

  - Cacti is a robust performance and fault management framework and a frontend to RRDTool - a Time Series
    Database (TSDB). Bypassing an earlier fix (CVE-2023-39360) that leads to a DOM XSS attack. Exploitation of
    the vulnerability is possible for an authorized user. The vulnerable component is the `graphs_new.php`.
    Impact of the vulnerability - execution of arbitrary javascript code in the attacked user's browser. This
    issue has been patched in version 1.2.26. (CVE-2023-49086)

  - Cacti is an open source operational monitoring and fault management framework. The fix applied for
    CVE-2023-39515 in version 1.2.25 is incomplete as it enables an adversary to have a victim browser execute
    malicious code when a victim user hovers their mouse over the malicious data source path in
    `data_debug.php`. To perform the cross-site scripting attack, the adversary needs to be an authorized
    cacti user with the following permissions: `General Administration>Sites/Devices/Data`. The victim of this
    attack could be any account with permissions to view `http://<HOST>/cacti/data_debug.php`. As of time of
    publication, no complete fix has been included in Cacti. (CVE-2023-49088)
