However, scenarios exist where the client has higher privileges, such as a performance monitor running as a domain controller obtaining data from a domain member via IPC. In these cases, the server can be compromised and send crafted data to the client. Despite the increase in Windows client applications, existing research has overlooked potential client-side vulnerabilities, which can be equally harmful. This paper introduces GLEIPNIR, the first vulnerability detection tool for Windows remote IPC clients. GLEIPNIR identifies client-side vulnerabilities by fuzzing IPC call return values and introduces a snapshot technology to enhance testing efficiency. Experiments on 76 client applications demonstrate that GLEIPNIR can identify 25 vulnerabilities within 7 days, resulting in 14 CVEs and a bounty of $36,000.  ABOUT NDSS The Network and Distributed System Security Symposium (NDSS) fosters information exchange among researchers and practitioners of network and distributed system security. The target audience includes those interested in practical aspects of network and distributed system security, with a focus on actual system design and implementation. A major goal is to encourage and enable the Internet community to apply, deploy, and advance the state of available security technologies.  Our thanks to the Network and Distributed System Security (NDSS) Symposium for publishing their Creators, Authors and Presenter’s superb NDSS Symposium 2025 Conference content on the Organizations' YouTube Channel.

Researchers from the Chinese Academy of Sciences and University of Minnesota introduced GLEIPNIR, the first vulnerability detection tool targeting Windows remote IPC clients. The tool focuses on scenarios where a privileged client receives data from a potentially compromised server, an overlooked attack surface. GLEIPNIR fuzzes IPC call return values and uses snapshot technology to improve testing efficiency. Testing across 76 client applications uncovered 25 vulnerabilities in 7 days, yielding 14 CVEs and $36,000 in bug bounties. The research was presented at NDSS 2025.
