Once that object number is received, an attacker can populate the “” value with that number in a SOAP request, wsa:Action get_personal_address_list, using the same POST endpoint, as shown below. The printer will respond with an address book enumeration object number, which is ‘5’ in this instance: This instructs the printer to prepare an address book object to be downloaded containing all sensitive data configured in the address book. The screenshot below describes submitting an unauthenticated SOAP request to that service, `POST /ws/km-wsdl/setting/address_book` with the described XML. In order to exploit the vulnerability, an attacker need only be on a network that can reach the MFP's listening SOAP service on port 9091/TCP. Those address books, in turn, contain stored email addresses, usernames, and passwords, which are normally used to store scanned documents on external services or send to users over email. While the API supports authentication, and the thick client performs this authentication, while capturing the SOAP requests, it was observed that the specific request to extract an address book, `POST /ws/km-wsdl/setting/address_book` does not require an authenticated session to submit. Kyocera exposes a SOAP API on port 9091/TCP used for remote printer management via the Net Viewer thick client application. It is being disclosed in accordance with Rapid7's vulnerability disclosure policy. This issue, CVE-2022-1026, was discovered by security researcher Aaron Herndon of Rapid7. These printers can be routinely found in both home office and enterprise environments around the world. Two such supported and tested models of MFPs are the ECOSYS M2640idw and the TASKalfa 406ci. Many Kyocera multifunction printers (MFPs) can be administered using Net Viewer. This vulnerability is an instance of CWE-522: Insufficiently Protected Credentials, and has an estimated base CVSS 3.1 score of 8.6, given that the credentials exposed are used to authenticate to other endpoints, such as external FTP and SMB servers.
Now that you have your personal address book or custom contacts group created, you can add contacts to it.Rapid7 researcher Aaron Herndon has discovered that several models of Kyocera multifunction printers running vulnerable versions of Net View unintentionally expose sensitive user information, including usernames and passwords, through an insufficiently protected address book export function. In the Address Book dialog box, verify that the address book you just created appears in the Address Book list. From your Inbox, click the Home tab > Address Book. To make sure your folder is available as an address book, right-click the new folder, and then click Properties.Ĭlick the Outlook Address Book tab, and make sure that the check box for Show this folder as an e-mail Address Book is selected.Ĭonfirm that the new contacts folder was added as an address book. It’s probably best to place the new folder in the Contacts folder.
In the Create New Folder dialog box, name the folder, select where to place it, and then click OK. On the Home tab, under My Contacts, right-click the Contacts folder, and then click New Folder. Select the People tab at the bottom of your Outlook screen. To do this, create a folder under Contacts, and then make that folder an address book. To make this easier, you can create personal address books using the names in your Outlook contact folders. When you send an email, you might want to look up and select an email address from a specific group of contacts, like a group of coworkers, relatives, or a club.
