Solaris SunSSH version 11.0 on x86 libpam remote root exploit.
678892d62f9d4edd74e135ec10ed7cd1fb0389a420617db1549d49e581caa0dbThis Metasploit module exploits a stack-based buffer overflow in the Solaris PAM library's username parsing code, as used by the SunSSH daemon when the keyboard-interactive authentication method is specified. Tested against SunSSH 1.1.5 on Solaris 10u11 1/13 (x86) in VirtualBox, VMware Fusion, and VMware Player. Bare metal untested. Your addresses may vary.
255a53ba4764640c38d52b8d61674d66f25d7a11c08ebc0d8b26cc5cdb1d4aceSolaris SunSSH versions 10 through 11.0 on x86 libpam remote root exploit.
93c50138db56dcc96e612d0fa56cca01459695d4f656345667a2e4fdec807e5dA trivial to reach stack-based buffer overflow is present in libpam on Solaris. The vulnerable code exists in pam_framework.c parse_user_name() which allocates a fixed size buffer of 512 bytes on the stack and parses a username supplied to PAM modules (such as authtok_get used by SunSSH). This issue can be reached remotely pre-authentication via SunSSH when "keyboard-interactive" is enabled to use PAM based authentication. The vulnerability was discovered being actively exploited by FireEye in the wild and is part of an APT toolkit called "EVILSUN". The vulnerability is present in both SPARC/x86 versions of Solaris and others (eg. illumos). This exploit uses ROP gadgets to disable nxstack through mprotect on x86 and a helper shellcode stub. Tested against latest Solaris 10 without patch applied and the configuration is vulnerable in a default vanilla install. This exploit requires libssh2, the vulnerability has been identified and confirmed reachable on Solaris 10 through 11.0.
