According to its self-reported version, the LibreOffice application running on the remote host is prior to 7.2.7 or 7.3.3. It is, therefore, affected by multiple vulnerabilities:
  - LibreOffice supports the storage of passwords for web connections in the user's configuration database. The stored     passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where the     required initialization vector for encryption was always the same which weakens the security of the encryption     making them vulnerable if an attacker has access to the user's configuration data.  (CVE-2022-26306)

  - LibreOffice supports the storage of passwords for web connections in the user's configuration database. The stored   passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where the master   key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making the stored passwords vulerable   to a brute force attack if an attacker has access to the users stored config. (CVE-2022-26307)

    Multiple vulnerabilities were found in LibreOffice an     office productivity software suite, leading to arbitrary script     execution, improper certificate validation, and weak encryption     of password storage in the user??s configuration database.

    CVE-2021-25636

        Only use X509Data         LibreOffice supports digital signatures of ODF documents and macros         within documents, presenting visual aids that no alteration of the         document occurred since the last signing and that the signature is         valid. An Improper Certificate Validation vulnerability in LibreOffice         allowed an attacker to create a digitally signed ODF document, by         manipulating the documentsignatures.xml or macrosignatures.xml stream         within the document to contain both X509Data and KeyValue children         of the KeyInfo tag, which when opened caused LibreOffice to verify         using the KeyValue but to report verification with the unrelated         X509Data value.

    CVE-2022-3140

        Insufficient validation of vnd.libreoffice.command         URI schemes. LibreOffice supports Office URI Schemes to enable browser         integration of LibreOffice with MS SharePoint server. An additional         scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In         the affected versions of LibreOffice links using that scheme could be         constructed to call internal macros with arbitrary arguments. Which         when clicked on, or activated by document events, could result in         arbitrary script execution without warning.

    CVE-2022-26305

        Compare authors using Thumbprint         An Improper Certificate Validation vulnerability in LibreOffice         existed where determining if a macro was signed by a trusted author         was done by only matching the serial number and issuer string of the         used certificate with that of a trusted certificate. This is not         sufficient to verify that the macro was actually signed with the         certificate. An adversary could therefore create an arbitrary         certificate with a serial number and an issuer string identical to a         trusted certificate which LibreOffice would present as belonging to         the trusted author, potentially leading to the user to execute         arbitrary code contained in macros improperly trusted.

    CVE-2022-26306

        LibreOffice supports the storage of passwords for         web connections in the user??s configuration database. The stored         passwords are encrypted with a single master key provided by the         user. A flaw in LibreOffice existed where the required initialization         vector for encryption was always the same which weakens the security         of the encryption making them vulnerable if an attacker has access to         the user's configuration data

    CVE-2022-26307

        Add Initialization Vectors to password storage.
        LibreOffice supports the storage of passwords for web connections in         the user??s configuration database. The stored passwords are encrypted         with a single master key provided by the user.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0072 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2022-26305:
    An Improper Certificate Validation vulnerability in LibreOffice existed where determining if a macro was     signed by a trusted author was done by only matching the serial number and issuer string of the used     certificate with that of a trusted certificate. This is not sufficient to verify that the macro was     actually signed with the certificate. An adversary could therefore create an arbitrary certificate with a     serial number and an issuer string identical to a trusted certificate which LibreOffice would present as     belonging to the trusted author, potentially leading to the user to execute arbitrary code contained in     macros improperly trusted. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to     7.2.7; 7.3 versions prior to 7.3.1.

    CVE-2022-26306:
    LibreOffice supports the storage of passwords for web connections in the users configuration database.
    The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice     existed where the required initialization vector for encryption was always the same which weakens the     security of the encryption making them vulnerable if an attacker has access to the user's configuration     data. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions     prior to 7.3.1.

    CVE-2022-26307:
    LibreOffice supports the storage of passwords for web connections in the users configuration database.
    The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice     existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making     the stored passwords vulerable to a brute force attack if an attacker has access to the users stored     config. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions     prior to 7.3.3.

    CVE-2022-3140:
    LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint     server. An additional scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In the affected     versions of LibreOffice links using that scheme could be constructed to call internal macros with     arbitrary arguments. Which when clicked on, or activated by document events, could result in arbitrary     script execution without warning. This issue affects: The Document Foundation LibreOffice 7.4 versions     prior to 7.4.1; 7.3 versions prior to 7.3.6.

    CVE-2022-38745:
    Apache OpenOffice versions before 4.1.14 may be configured to add an empty entry to the Java class path.
    This may lead to run arbitrary Java code from the current directory.

    CVE-2023-0950:
    Improper Validation of Array Index vulnerability in the spreadsheet component of The Document Foundation     LibreOffice allows an attacker to craft a spreadsheet document that will cause an array index underflow     when loaded. In the affected versions of LibreOffice certain malformed spreadsheet formulas, such as     AGGREGATE, could be created with less parameters passed to the formula interpreter than it expected,     leading to an array index underflow, in which case there is a risk that arbitrary code could be executed.
    This issue affects: The Document Foundation LibreOffice 7.4 versions prior to 7.4.6; 7.5 versions prior to     7.5.1.

    CVE-2023-1183:
    A flaw was found in the Libreoffice package. An attacker can craft an odb containing a database/script     file with a SCRIPT command where the contents of the file could be written to a new file whose location     was determined by the attacker.

    CVE-2023-2255:
    Improper access control in editor components of The Document Foundation LibreOffice allowed an attacker to     craft a document that would cause external links to be loaded without prompt. In the affected versions of     LibreOffice documents that used floating frames linked to external files, would load the contents of     those frames without prompting the user for permission to do so. This was inconsistent with the treatment     of other linked content in LibreOffice. This issue affects: The Document Foundation LibreOffice 7.4     versions prior to 7.4.7; 7.5 versions prior to 7.5.3.
