This vulnerability affects all systems that support the use of SATAN with the HTML interface. The CERT team recommends that you take the precautions described in Section III below before you run SATAN and that you upgrade to SATAN version 1.1 when available. As we receive additional information relating to this advisory, we will place it in ftp://info.cert.org/pub/cert_advisories/CA-95:07.README We encourage you to check our README files regularly for updates on advisories. For an overview of SATAN (Security Administrator Tool for Analyzing Systems), see CERT advisory CA-95:06. ----------------------------------------------------------------------------- I. Description In SATAN version 1.0, it is possible for unauthorized users to gain root access to systems during the time SATAN is running from the root account. This vulnerability exploits a weakness in the HTML server started by SATAN on a random, high-numbered TCP port. Additional details on this vulnerability will be found in the SATAN documentation provided with SATAN version 1.1 when version 1.1 is released. II. Impact Unauthorized users can execute programs as root. Access to an account on the system may not be necessary to do this. III. Solution It is expected that SATAN version 1.1 will fix this problem, and if possible you should wait for this version before running SATAN. The following precautions will prevent the introduction of this vulnerability while you are running SATAN and are recommended whether you are running SATAN version 1.0 or 1.1. 1. Install all relevant security patches for the system on which you will run SATAN. 2. Execute SATAN only from the console of the system on which it is installed (e.g., do not run SATAN from an X terminal, from a diskless workstation, or from a remote host). 3. Ensure that the SATAN directory tree is not NFS-mounted from a remote system. 4. Ensure that the SATAN directory tree cannot be read by users other than root. Note that SATAN 1.1 is expected to check systems for this SATAN 1.0 vulnerability as part of scanning other systems. --------------------------------------------------------------------------- If you believe that your system has been compromised, contact the CERT Coordination Center or your representative in the Forum of Incident Response and Security Teams (FIRST).
