Summary

Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Kernel). Supported versions that are affected are 10 and 11. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Solaris executes to compromise Solaris. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Solaris accessible data as well as unauthorized read access to a subset of Solaris accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Solaris. CVSS 3.0 Base Score 5.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

Metasploit

descriptionThis 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 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 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 module has been tested successfully on Solaris 11.1 (x86) and Solaris 11.3 (x86).

descriptionThe remote Solaris host is missing a vendor-supplied security patch. It is, therefore, affected by the following vulnerabilities : - Multiple security bypass vulnerabilities exist in the Kernel subcomponent that allow a specially crafted application to circumvent the stack guard page security mechanism. A local attacker can exploit these, by using stack clash methods, to gain elevated privileges. (CVE-2017-3629, CVE-2017-3630) - A privilege escalation vulnerability exists in the Kernel subcomponent when UID binaries are invoked via a hard-link using a different pathname. A local attacker can exploit this to gain elevated privileges. (CVE-2017-3631)
