Lister les bulletins de sécurité MS publiés entre deux dates / List MS security bulletins published during a date range


Go to English version

Lors de l’un de mes onsites suite à un IIS RaaS+, je me suis trouvé confronté à un serveur qui n’avait pas été patché depuis le 02 Avril 2012 (!). Je ne m’attarderai pas ici sur les risques encourus et la difficulté (pour ne pas dire impossibilité)  de la remédiation. Mais une question m’est venue à l’esprit : Combien de bulletins de sécurité Microsoft a publié depuis cette date ?

En cherchant un peu j’ai vu que la page https://technet.microsoft.com/en-us/security/bulletins me donnait les informations dont j’avais besoin. En poussant un peu plus loin l’analyse à l’aide d’une trace réseau j’ai vu que le résultat était transmis en JSON via une URI du type https://technet.microsoft.com/security/bulletin/services/GetBulletins?searchText=&sortField=0&sortOrder=1&currentPage=1&bulletinsPerPage=15&locale=en-us. Il ne restait plus qu’à manipuler les données JSON en PowerShell (nativement avec la cmdlet ConvertFrom-Json). Je vous propose donc ici la version de mon script.

 

Ce script est aussi disponible dans le TechNet Script Center : https://gallery.technet.microsoft.com/List-MS-security-bulletins-2b545eb2

During one of my onsites following an IIS RaaS+, I faced to a server that had not been patched since April 2, 2012 (!). I will not dwell here on the risks involved and the difficulty (or the impossibility) of the remediation. But one question came to my mind: How many security bulletins Microsoft has published since that date?


Looking for a bit, I saw that the https://technet.microsoft.com/en-us/security/bulletins page gave me the information I needed. By doing a deeper the analysis with a network trace I saw that the result was transmitted in JSON via a URI of the type https://technet.microsoft.com/security/bulletin/services/GetBulletins?searchText=&sortField=0&sortOrder=1&currentPage=1&bulletinsPerPage=15&locale=en-us. . All that was left to do was to manipulate the JSON data in PowerShell (natively with the ConvertFrom-Json cmdlet). So here I propose the version of my script.

 

The script file is also available at the TechNet Script Center repository, at: https://gallery.technet.microsoft.com/List-MS-security-bulletins-2b545eb2
