Detecting SDN Control Policy Manipulation Via Contextual Semantics Of Provenance Graphs
Software-Defined Networking (SDN) improves network flexibility by decoupling control functions (control plane) from forwarding devices (data plane). However, the logically centralized control plane is vulnerable to Control Policy Manipulation (CPM), which introduces incorrect policies by manipulating the controller's network view. Current methods for anomaly detection and configuration verification have limitations in detecting CPM attacks because they focus solely on the data plane. Certain covert CPM attacks are indistinguishable from normal behavior without analyzing the causality of the controller's decisions. In this paper, we propose ProvGuard, a provenance graph-based detection framework that identifies CPM attacks by monitoring controller activities. ProvGuard leverages static analysis to identify data-plane-related controller operations and guide controller instrumentation, constructing a provenance graph from captured control plane activities. ProvGuard reduces redundancies and extracts paths in the provenance graph as contexts to capture concise and long-term features. Suspicious behaviors are flagged by identifying paths that cause prediction errors beyond the normal range, based on a sequence-to-sequence prediction model. We implemented a prototype of ProvGuard on the Floodlight controller. Our approach successfully identified all four typical CPM attacks that previous methods could not fully address and provided valuable insights for investigating attack behaviors.

PAPER
A Large-Scale Measurement Study Of The PROXY Protocol And Its Security Implications
Reverse proxy servers play a critical role in optimizing Internet services, offering benefits ranging from load balancing to Denial of Service (DoS) protection. A known shortcoming of such proxies is that the backend server becomes oblivious to the IP address of the client who initiated the connection since all requests are forwarded by the proxy server. For HTTP, this issue is trivially solved by the X-Forwarded-For header, which allows the proxy server to pass to the backend server the IP address of the client that originated the request. Unfortunately, no such equivalent exists for many other protocols. To solve this issue, HAProxy created the PROXY protocol, which communicates client information from a proxy server to a backend server at a lower level in the network stack (Layer 4), making it protocol-agnostic. In this work, we are the first to study the use of the PROXY protocol at Internet scale and investigate the security impact of its misconfigurations. We launched a measurement study on the full IPv4 address range and found that, over HTTP, more than 170,000 hosts accept PROXY protocol data from arbitrary sources. We demonstrate how to abuse this protocol to bypass on-path proxies (and their protections) and leak sensitive information from backend infrastructures. We discovered over 10,000 servers that are vulnerable to an access bypass, triggered by injecting a (spoofed) PROXY protocol header. Using this technique, we obtained access to over 500 internal servers providing control over IoT monitoring platforms and smart home automation devices, allowing us to, for example, regulate remote controlled window blinds or control security cameras and alarm systems. Beyond HTTP, we demonstrate how the PROXY protocol can be used to turn over 350 SMTP servers into open relays, enabling an attacker to send arbitrary emails from any email address. In sum, our study exposes how PROXY protocol misconfigurations lead to severe security issues that affect multiple protocols prominently used in the wild.

PAPER
ReDAN: An Empirical Study On Remote DoS Attacks Against NAT Networks
In this paper, we conduct an empirical study on remote DoS attacks targeting NAT networks (ReDAN, short for Remote DoS Attacks targeting NAT). We show that Internet attackers operating outside local NAT networks possess the capability to remotely identify a NAT device and subsequently terminate TCP connections initiated from the identified NAT device to external servers. Our attack involves two steps. First, we identify NAT devices on the Internet by exploiting inadequacies in the Path MTU Discovery (PMTUD) mechanism within NAT specifications. This deficiency creates a fundamental side channel that allows Internet attackers to distinguish if a public IPv4 address serves a NAT device or a separate IP host, aiding in the identification of target NAT devices. Second, we launch a remote DoS attack to terminate TCP connections on the identified NAT devices. While recent NAT implementations may include protective measures, such as packet legitimacy validation to prevent malicious manipulations on NAT mappings, we discover that these safeguards are not widely adopted in real world. Consequently, attackers can send crafted packets to deceive NAT devices into erroneously removing innocent TCP connection mappings, thereby disrupting the NATed clients to access remote TCP servers. Our experimental results reveal widespread security vulnerabilities in existing NAT devices. After testing 8 types of router firmware and 30 commercial NAT devices from 14 vendors, we identify vulnerabilities in 6 firmware types and 29 NAT devices that allow off-path removal of TCP connection mappings. Moreover, our measurements reveal a stark reality: 166 out of 180 (over 92%) tested real-world NAT networks, comprising 90 4G LTE/5G networks, 60 public Wi-Fi networks, and 30 cloud VPS networks, are susceptible to exploitation. We responsibly disclosed the vulnerabilities to affected vendors and received a significant number of acknowledgments. Finally, we propose our countermeasures against the identified DoS attack.

PAPER
GadgetMeter: Quantitatively And Accurately Gauging The Exploitability Of Speculative Gadgets
Since their emergence in 2018, speculative execution attacks have proven difficult to fully prevent without substantial performance overhead. This is because most mitigations hurt modern processors' speculative nature, which is essential to many optimization techniques. To address this, numerous scanners have been developed to identify vulnerable code snippets (speculative gadgets) within software applications, allowing mitigations to be applied selectively and thereby minimizing performance degradation. In this paper, we show that existing speculative gadget scanners lack accuracy, often misclassifying gadgets due to limited modeling of timing properties. Instead, we identify another fundamental condition intrinsic to all speculative attacks--the timing requirement as a race condition inside the gadget. Specifically, the attacker must optimize the race condition between speculated authorization and secret leakage to successfully exploit the gadget. Therefore, we introduce GadgetMeter, a framework designed to quantitatively gauge the exploitability of speculative gadgets based on their timing property. We systematically explore the attacker's power to optimize the race condition inside gadgets (windowing power). A Directed Acyclic Instruction Graph is used to model timing conditions and static analysis and runtime testing are combined to optimize attack patterns and quantify gadget vulnerability. We use GadgetMeter to evaluate gadgets in a wide range of software, including six real-world applications and the Linux kernel. Our result shows that GadgetMeter can accurately identify exploitable speculative gadgets and quantify their vulnerability level, identifying 471 gadgets reported by GadgetMeter works as unexploitable.
