CERTFR-2022-ALE-008

Vulnerability from certfr_alerte - Published: 2022-09-30 - Updated: 2023-03-14

[Mise à jour du 09 novembre 2022] L'éditeur a publié un correctif (cf. section solution).

En date du 29 septembre 2022, Microsoft a indiqué l'existence de deux vulnérabilités, de type zéro-jour, au sein de Windows Exchange 2013, 2016 et 2019.

Ces vulnérabilités sont les suivantes :

CVE-2022-41040 : Vulnérabilité de type injection de requêtes forgées côté serveur (Server Side Request Forgery, SSRF) exploitable par un attaquant authentifié ;
CVE-2022-41082 : Vulnérabilité permettant à un attaquant authentifié d'exécuter du code arbitraire à distance.

Dans le cadre d'une attaque, la CVE-2022-41040 peut permettre à un attaquant d'exploiter à distance la CVE-2022-41082. Selon l'éditeur, ces deux vulnérabilités ne sont exploitables que si l'attaquant est déjà authentifié. Un correctif spécifique est en cours de développement par Microsoft.

Ces vulnérabilités doivent faire l'objet d'une prise en compte immédiate, car elles ont été utilisées dans le cadre d'attaques ciblées. Le CERT-FR n'a pour le moment pas connaissance des conditions ayant permis aux attaquants d'obtenir un accès authentifié sur les serveurs ciblés.

Le CERT-FR a connaissance de codes d'exploitation publics pour la CVE-2022-41040.

Le CERT-FR a connaissance d'incidents en France impliquant l'exploitation de ces vulnérabilités.

Contournement provisoire

En attendant la publication des correctifs, le CERT-FR recommande d'appliquer immédiatement les mesures d'atténuation proposées par Microsoft [1].

L'éditeur recommande fortement de désactiver l’accès à PowerShell à distance pour les utilisateurs non administrateurs [3]. Le CERT-FR recommande l'application de cette contre-mesure car il s'agit de la protection la plus efficace identifiée à ce jour. Il conviendra de tester la configuration afin d'identifier les éventuels effets de bord sur les procédures automatisées basées sur Powershell.

Par ailleurs, et de façon complémentaire, Microsoft a publié un code PowerShell permettant d'appliquer les mesures d'atténuation pour la CVE-2022-41040 (réécriture de l'URL) [2]. De plus, une mise à jour de l'outil EEMS (Exchange Emergency Mitigation Service), ainsi que des éléments pour l'outil AMSI (AntiMalware Scan Interface) ont été proposés par Microsoft.

Le code PowerShell de Microsoft permettant d'appliquer la mesure d'atténuation via le module URL Rewrite a été mis à jour pour renforcer son efficacité contre des variations de la requête malveillante initialement observée [2]. Afin d'appliquer cette modification, il est nécessaire de télécharger puis relancer ce nouveau code ou modifier directement la règle dans le module URL Rewrite avec la valeur suivante : ".*autodiscover\.json.*Powershell.*".

Afin de prévenir tout type de coutournement de la règle ".*autodiscover\.json.*Powershell.*" par le biais d'encodage, le CERT-FR rappelle qu'il faut modifier la condition d'entrée de la règle susmentionnée avec la valeur suivante : {UrlDecode:{REQUEST_URI}}. Pour plus d'informations, veuillez-vous référer à l'étape 10 du blog de Microsoft [1].

Le Microsoft Patch Tuesday du 11 octobre 2022 ne propose aucun correctif pour ces vulnérabilités. Il est essentiel de maintenir l'application des contournements mentionnés ci-avant.

Détection

Le billet de blogue de l'éditeur documente quelques éléments d'aide à la détection de ces vulnérabilités [1].

Le CERT-FR recommande de réaliser une analyse approfondie des journaux réseau des serveurs IIS (sauvegardés par défaut dans le dossier : %SystemDrive%\inetpub\logs\LogFiles). Les commandes suivantes permettent d'identifier une exploitation de la vulnérabilité CVE-2022-41040 :

sur un système Windows : Get-ChildItem -Recurse -Path <Path_IIS_Logs> -Filter "*.log" | Select-String -Pattern '/powershell.*autodiscover.json.*200';
sur un système Linux : cat <Path_IIS_Logs>/*.log | grep -i -e '/powershell.*autodiscover.json.*200'.

Si une répartition de charge (load-balancing) est mise en œuvre, ces commandes doivent être appliquées sur les journaux de chacun des nœuds. Il est possible d'identifier une exploitation réussie de la CVE-2022-41040 si, à la suite de la première requête, une seconde requête HTTP de type POST commençant par le motif : /PowerShell a été exécutée par le serveur. Dans ce cas là, une analyse forensique des serveurs Exchange doit être engagée.

En cas de suspicion de compromission, les bons réflexes en cas d'intrusion sur votre système d'information sont rappelés ici.

    "description": "It was originally reported that an undisclosed flaw in Microsoft Exchange Server version 2019 and possibly earlier allowed for remote code execution. Confirmation was not available at the time of the release of the original GSD identifiers (GSD-2022-1006324 and GSD-2022-1006325) however, since then, Microsoft has confirmed that these two issues can be combined to gain remote code execution (an SSRF and a Remote Code Execution via Powershell). Microsoft has assigned CVE ID\u0027s for these two issues, as such the original GSD Identifiers have been withdrawn, and the corresponding GSD ID\u0027s for the CVE ID\u0027s have been populated with data (the file you are currently reading). \n\n This issue was originally reported and also reportedly confirmed as ZDI-CAN-18333 (CVSS score of 8.8) and ZDI-CAN-18802 (CVSS score of 6.3). \n\n Microsoft now reports the following: \n\n # Summary \n\n Microsoft is investigating two reported zero-day vulnerabilities affecting Microsoft Exchange Server 2013, 2016, and 2019. The first vulnerability, identified as CVE-2022-41040, is a Server-Side Request Forgery (SSRF)  vulnerability, while the second, identified as CVE-2022-41082, allows remote code execution (RCE) when PowerShell is accessible to the attacker. \n\n At this time, Microsoft is aware of limited targeted attacks using the two vulnerabilities to get into users\u2019 systems.  In these attacks, CVE-2022-41040 can enable an authenticated attacker to remotely trigger CVE-2022-41082. It should be noted that authenticated access to the vulnerable Exchange Server is necessary to successfully exploit either of the two vulnerabilities. \n\n We are working on an accelerated timeline to release a fix. Until then, we\u2019re providing the mitigations and detection guidance below to help customers protect themselves from these attacks. \n\n Microsoft Exchange Online has detections and mitigation in place to protect customers. Microsoft is also monitoring these already deployed detections for malicious activity and will take necessary response actions to protect customers. \n\n We will continue to provide updates here to help keep customers informed. \n\n # Mitigations \n\n Mitigation information is available at https://msrc-blog.microsoft.com/2022/09/29/customer-guidance-for-reported-zero-day-vulnerabilities-in-microsoft-exchange-server/ \n\n # Detections \n\n Detection information is available at https://msrc-blog.microsoft.com/2022/09/29/customer-guidance-for-reported-zero-day-vulnerabilities-in-microsoft-exchange-server/ \n\n # Updates \n\n September 30, 2022 updates: \n\n Microsoft created a script for the URL Rewrite mitigation steps and modified step 6 in the Mitigations section. \n Antimalware Scan Interface (AMSI) guidance, and auditing AV exclusions to optimize detection, and blocking of the Exchange vulnerability exploitation. \n Microsoft Sentinel hunting queries \n\n ## Detection \n\n Fast Fuzzer (written in Go) can detect this: \n\n ffuf -w \"urllist.txt:URL\" -u \"https://URL/autodiscover/autodiscover.json?@URL/\u0026Email=autodiscover/autodiscover.json%3f@URL\" -mr \"IIS Web Core\" -r \n\n",
