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. IBM Patch Information ftp://aix.software.ibm.com/aix/efixes/security/sdrd.tar.Z CIAC, the Computer Incident Advisory Capability, is the computer security incident response team for the U.S. Department of Energy (DOE) and the emergency backup response team for the National Institutes of Health (NIH). CIAC is located at the Lawrence Livermore National Laboratory in Livermore, California. CIAC is also a founding member of FIRST, the Forum of Incident Response and Security Teams, a global organization established to foster cooperation and coordination among computer security teams worldwide.
