07 August 1998
The U.S. Department of Energy Computer Incident Advisory Capability
(CIAC) has released the following advisory concerning a security

IBM AIX "sdrd" daemon Vulnerability
August 4, 1998 20:00 GMT Number I-079
PROBLEM: A vulnerability exists in "sdrd" daemon that allows other nodes
to make request, thereby allowing remote retrieval of any file
off the system possible.
PLATFORM: IBM SP2.
DAMAGE: By exploiting this vulnerability, remote users may gain access
to the system.
SOLUTION: Apply the patch indicated below.
VULNERABILITY Currently, there are no reports of this vulnerability being
ASSESSMENT: exploited. However, CIAC recommends that all systems running
the "sdrd" daemon be patched immediately.
CIAC has been informed of a security vulnerability with "sdrd" daemon
running on the IBM SP2 platform. This vulnerability may allow remote users
to retrieve files on the System Data Repository (SDR) machine, thereby
allowing remote users to gain access to the system.
The System Data Repository (SDR) is a SP subsystem that stores SP
configuration and some operational information. The SDR information is stored
on a Control Workstation, but is made available through a client/server
interface to other network-connected nodes. In most cases, SDR interaction is
performed using the SDR command-line interface. However, the "sdrd" daemon
allows other nodes to make request without performing any authentication.
This security flaw allows anyone to use the retrieve file command to get any
file on the SRD system.
CIAC is unaware of any workarounds. The only alternative is to download
and install the patch provided by IBM.
