Oracle XMLDB FTP Service Audit Log Vulnerability
------------------------------------------------------------------------

SUMMARY

Oracle XML DB FTP service may incorrectly perform login audit trails in
some circumstances. Attackers may exploit this issue to hide or obfuscate
actual attack traces.

DETAILS

Vulnerable Systems:
* Oracle Oracle 9ir2, 10g Release 1

When a user attempts to log in via the XDB ftp service the audit trail
shows an incorrect entry for USERID. This can present two subtle problems.

Firstly, if a user logs in as SYSTEM the USERID column only shows SYSTE
- only 5 characters.

The second problem is that if the same user then attempts to log in a
user FOO , FOOTE is logged in the USERID column - the TE coming from
the TE of SYSTE[M] - the previous login. This only happens on the same
connected TCP circuit; as such all audit entries have the same SESSIONID.

Vendor Status:
Oracle was alerted to this flaw on the 9th of March 2006. A patch has now
been made available:
