Impact

Security vulnerabilities with telnet(1), Secure Shell (SSH), and httpd in the Sun SPARC Enterprise M4000/M5000/M8000/M9000 XSCF Control Package (XCP) firmware versions prior to 1050 may allow a remote unprivileged user to cause a Denial of Service (DoS).


Contributing Factors

This issue can occur on the following platforms:

  • SPARC Enterprise M4000/M5000/M8000/M9000 servers with XSCF Control Package (XCP) firmware versions prior to 1050.

To determine the version of XCP firmware installed on a system, the following command can be used at the XSCF> prompt:

    XSCF> version -c xcp
    XSCF#0 (Active )
    XCP0 (Current): 1050
    XCP1 (Reserve): 1050
    XSCF>

If the value under "Current" is less than 1050, the system may be vulnerable to this issue.


Symptoms

If the described issue occurs, the eXtended System Control Facility (XSCF) response may degrade and the XSCF will reboot whenever an "Out of Memory" condition occurs. Issues connecting to the XSCF may also be experienced.


Workaround

There is no workaround for this issue.  Please see the Resolution section below.


Resolution

This issue is addressed in the following releases:

  • XCP version 1050 or later for SPARC Enterprise M4000/M5000/M8000/M9000 servers

Internal Comments
6574635 - telnet vulnerability where it is possible to initiate a large
number of telnet connections against the XSCF and cause the XSCF to
experience out-of-memory conditions.
6548161 - SSH vulnerability where it is possible to issue an infinite
number of remote SSH commands to the XSCF and cause the XSCF to
experience resource allocation issues.
6546970 - httpd vulnerability where large numbers of requests can
trigger httpd to spawn additional processes causing the XSCF to experience
out-of-memory conditions.
All of these vulnerabilities are related to
the configuration of these services
on the "XSCF" and are not due to issues with the services themselves.
