This one ends with uid=0(root) - with an asterisk. Ten context windows. A UTF-8 encoding barrier that blocks every libc address. A PLT mapping that lied. A stack alignment problem solved by a NULL pointer and a filename that shouldn't exist. The story of how a pre-auth xrdp overflow became (almost) pure-network RCE - through the most absurd gadget chain we've ever built.Wed, 04 Mar 2026 22:00:00 -0400https://exploit-intel.com/blog/posts/cve-2025-68670-xrdp-pre-auth-overflow-the-hard-one/https://exploit-intel.com/blog/posts/cve-2025-68670-xrdp-pre-auth-overflow-the-hard-one/xrdp. Pre-authentication. A full RDP handshake implemented from scratch. UTF-8 encoding constraints that break your ROP chain. A false crash path that wasted hours. And a 3-byte partial overwrite technique that reaches any address in the binary. Stackforge's hardest target yet - and the most honest result.Wed, 04 Mar 2026 18:00:00 -0400
