"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)

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