PAPER
A Multifaceted Study on the Use of TLS and Auto-detect in Email Ecosystems
Various email protocols, including IMAP, POP3, and SMTP, were originally designed as "plaintext" protocols without inbuilt confidentiality and integrity guarantees. To protect the communication traffic, TLS can either be used implicitly before the start of those email protocols, or introduced as an opportunistic upgrade in a post-hoc fashion. In order to improve user experience, many email clients nowadays provide a so-called "auto-detect" feature to automatically determine a functional set of configuration parameters for the users. In this paper, we present a multifaceted study on the security of the use of TLS and auto-detect in email clients. First, to evaluate the design and implementation of client-side TLS and auto-detect, we tested 49 email clients and uncovered various flaws that can lead to covert security downgrade and exposure of user credentials to attackers. Second, to understand whether current deployment practices adequately avoid the security traps introduced by opportunistic TLS and auto-detect, we collected and analyzed 1102 email setup guides from academic institutes across the world, and observed problems that can drive users to adopt insecure email settings. Finally, with the server addresses obtained from the setup guides, we evaluate the sever-side support for implicit and opportunistic TLS, as well as the characteristics of their certificates. Our results suggest that many users suffer from an inadvertent loss of security due to careless handling of TLS and auto-detect, and organizations in general are better off prescribing concrete and detailed manual configuration to their users.

PAPER
Automatic Insecurity: Exploring Email Auto-configuration in the Wild
Email clients that support auto-configuration mechanisms automatically retrieve server configuration information, such as the hostname, port number, and connection type, allowing users to log in by simply entering email addresses and passwords. Auto-configuration mechanisms are being increasingly adopted. However, the security implications of these mechanisms, both in terms of implementation and deployment, have not yet been thoroughly studied. In this paper, we present the first systematic analysis of security threats associated with email auto-configuration and evaluate their impacts. We summarize 10 attack scenarios, covering 17 defects (including 8 newly identified ones), along with 4 inadequate client UI notifications. These attack scenarios can either cause a victim to connect to an attacker-controlled server or establish an insecure connection, putting the victim's credentials at risk. Moreover, our large-scale measurements and in-depth analysis revealed serious insecurity of auto-configuration applications in the wild. On the server-side, we discovered 49,013 domains, including 19 of the Top-1K popular domains, were misconfigured. On the client-side, 22 out of 29 clients were vulnerable to those threats. Moreover, 27 out of 29 clients exhibited at least one UI-notification defect that facilitates silent attacks. These defects arise from misconfiguration, mismanagement, flawed implementation and compatibility. We hope this paper raises attention to email auto-configuration security.
