The tools being used to accomplish the breakins appear to be those principally written by a Polish hacking crew using the name "Last Stages of Delirium". Similar tools that take advantage of the same vulnerabilities are available from elsewhere, too. We have researched as many as we have been aware of software tools that are being used to see if any of the vulnerabilities have or have not been closed under AIX. So far, we have determined that of all the vulnerabilties these tools exploit have been fixed by IBM, dating back to 1996. APARs for all of the vulnerabilities have been available to customers. Here is a listing of the exploits we know of being used to gain access to AIX systems during the recent attacks and the AIX version numbers and APAR numbers associated with the fix for that version: 1. chatmpvc, mkatmpvc, rmatmpvc 4.3, APAR #IY08128 4.2, APAR #IY08288 2. digest 4.3, APAR #IX74599 4.2, APAR #IX76272 4.1, APAR #IX74457 3. dtaction 4.3, APAR #IY02944 4. dtprintinfo 4.3, APAR #IY06367 4.2, APAR #IY06547 5. ftpd 4.3, APAR #IY04477 4.2, APAR #IX85556 4.1, APAR #IX85555 6. nslookup 4.3, APAR #IY02120 4.3, APAR #IX9909 7. pdnsd Associated product out of service; Customers avised to disable and/or uninstall. 8. rpc.ttdbserverd 4.3, APAR #IX81442 4.2, APAR #IX81441 9. piobe, piomkapqd 4.3, APAR #IY12638 10. portmir 4.3, APAR #IY07832 11. sdrd SP systems only; 4.3, APAR #IX80724 12. setsenv 4.3, APAR #IY08812 13. telnetd E-fix available; 4.3, IY22029 5.1, IY22021 Affected customers are urged to upgrade the level of their AIX operating systems and/or apply the APARs listed above to protect their systems. - -----BEGIN PGP SIGNATURE----- Version: PGP 6.5.2 iQCVAwUBO4P/ewsPbaL1YgqvAQEiXwP/bwThtsNncjiuH6GWsxCR8NLM+fmGNn9x mk8mSGUOXPzP4o+f1RuGXwxaE6YcEQktcnal5v0VtPnz0u9/Sj6D4nVtsZl+Mh/D IMgz+ndY1NbyMjaNDxmlPAAOOXL2z3InhZ46nylCWzS7dMAnJxtN5WhnsYmkAO5d ReTJOZ3LdzQ= =rJ4O - -----END PGP SIGNATURE----- - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
