This Metasploit module exploits a vulnerability in xscreensaver versions since 5.06 on unpatched Solaris 11 systems which allows users to gain root privileges. xscreensaver allows users to create a user-owned file at any location on the filesystem using the -log command line argument introduced in version 5.06. This module uses xscreensaver to create a log file in /usr/lib/secure/, overwrites the log file with a shared object, and executes the shared object using the LD_PRELOAD environment variable. This module has been tested successfully on xscreensaver version 5.15 on Solaris 11.1 (x86) and xscreensaver version 5.15 on Solaris 11.3 (x86). View the full article

This Metasploit module exploits a vulnerability in RSH on unpatched Solaris systems which allows users to gain root privileges. The stack guard page on unpatched Solaris systems is of insufficient size to prevent collisions between the stack and heap memory, aka Stack Clash. This Metasploit module uploads and executes Qualys' Solaris_rsh.c exploit, which exploits a vulnerability in RSH to bypass the stack guard page to write to the stack and create a SUID root shell. This Metasploit module has offsets for Solaris versions 11.1 (x86) and Solaris 11.3 (x86). Exploitation will usually complete within a few minutes using the default number of worker threads (10). Occasionally, exploitation will fail. If the target system is vulnerable, usually re-running the exploit will be successful. This Metasploit module has been tested successfully on Solaris 11.1 (x86) and Solaris 11.3 (x86). View the full article

This Metasploit module exploits a directory traversal vulnerability in the dtappgather executable included with Common Desktop Environment (CDE) on unpatched Solaris systems prior to Solaris 10u11 which allows users to gain root privileges. dtappgather allows users to create a user-owned directory at any location on the filesystem using the DTUSERSESSION environment variable. This Metasploit module creates a directory in /usr/lib/locale, writes a shared object to the directory, and runs the specified SUID binary with the shared object loaded using the LC_TIME environment variable. This Metasploit module has been tested successfully on: Solaris 9u7 (09/04) (x86); Solaris 10u1 (01/06) (x86); Solaris 10u2 (06/06) (x86); Solaris 10u4 (08/07) (x86); Solaris 10u8 (10/09) (x86); Solaris 10u9 (09/10) (x86).

This Metasploit module exploits an arbitrary file write vulnerability in the Netscape Portable Runtime library (libnspr) on unpatched Solaris systems prior to Solaris 10u3 which allows users to gain root privileges. libnspr versions prior to 4.6.3 allow users to specify a log file with the `NSPR_LOG_FILE` environment variable. The log file is created with the privileges of the running process, resulting in privilege escalation when used in combination with a SUID executable. This Metasploit module writes a shared object to the trusted library directory `/usr/lib/secure` and runs the specified SUID binary with the shared object loaded using the `LD_LIBRARY_PATH` environment variable. This Metasploit module has been tested successfully with libnspr version 4.5.1 on Solaris 10u1 (01/06) (x86) and Solaris 10u2 (06/06) (x86). View the full article
