SQL Injection Vulnerability in Oracle WWV_FLOW_UTILITIES
------------------------------------------------------------------------
SUMMARY
The list of values (LOV) in wwv_flow_utilities.gen_popup_list contains a
SQL injection vulnerability. Depending of the APEX application it is
possible to inject custom SQL statements. The entire SQL statement is
accessible from the URL in the parameter P_LOV. To protect the SELECT
statement in the URL Oracle is using a MD5 checksum. By modifying the SQL
statement and recalculating the MD5 checksum P_LOV_CHECKSUM it is possible
to run custom SQL statements from the URL.
DETAILS
Affected Products:
This bug is fixed with 2.2 of APEX which is not part of the Critical Patch
Update October 2006. It's necessary to upgrade your APEX/HTMLDB
installation to 2.2 or better 2.2.1.. Keep in mind that APEX 2.2 is NOT
running on Oracle Application Express. Patches are currently not available
for Oracle Application Express.
