SQL injection vulnerability in wwv_flow_utilities.gen_popup_list in the WWV_FLOW_UTILITIES package for Oracle APEX/HTMLDB before 2.2 allows remote authenticated users to execute arbitrary SQL by modifying the P_LOV parameter and calculating a matching MD5 checksum for the P_LOV_CHECKSUM parameter. NOTE: it is likely that this issue is subsumed by CVE-2006-5351, but due to lack of details from Oracle, this cannot be proven.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
