Loading vulnerability…
CVE-2010-3904 is a local privilege escalation vulnerability in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation, affecting versions up to 2.6.36-rc8. The vulnerability is due to improper validation of user-supplied addresses in the rds_page_copy_user function, which uses unchecked _copy*_user_inatomic functions. This allows a local attacker to pass kernel addresses as iovec base addresses in recvmsg-style calls, resulting in arbitrary kernel memory overwrite. Exploitation involves overwriting the rds_ioctl function pointer to execute attacker-controlled code in kernel context, leading to root privilege escalation. The exploit is architecture-independent and does not require inline assembly.

This repository contains a single Metasploit module: 'Reliable Datagram Sockets (RDS) rds_page_copy_user Privilege Escalation' (CVE-2010-3904). The module targets a local privilege escalation vulnerability in the Linux kernel's RDS implementation (net/rds/page.c) affecting versions 2.6.30 to 2.6.36-rc8. The exploit works by uploading and executing a compiled C exploit (rds-fail.c or precompiled binaries) on the target, which triggers the vulnerability to execute a user-supplied payload as root. The default payload is a reverse meterpreter shell, but any compatible Metasploit payload can be used. The module checks for kernel version, RDS module availability, and module loading restrictions before exploitation. It requires a writable directory (default: /tmp) to drop binaries. The exploit is weaponized, fully integrated into Metasploit, and provides root access on vulnerable systems. The code references several fingerprintable file paths and system binaries for its checks and operations.
