Naam: Dangling Database Cursor

The product does not close a database cursor properly, leaving the cursor "dangling."

Algemene informatie

Achtergrondinformatie

Introductiemodi

Implementation : This issue is currently reported for unhandled exceptions, but it is theoretically possible any time the programmer does not close the cursor at the proper time.

Toepasselijke platforms

Taal

Naam: SQL (Undetermined)

Technologieën

Naam: Database Server (Undetermined)

Veelvoorkomende gevolgen

Bereik Impact Waarschijnlijkheid
Confidentiality
Integrity		Read Application Data, Modify Application Data

Opmerking: The cursor could become accessible to other users while retaining the same privileges that were originally assigned. The impact of the issue depends on the cursor's role, but SQL injection attacks are commonly possible.

Mogelijke risicobeperkingen

Phases : Implementation
Close cursors immediately after access to them is complete. Ensure that you close cursors if exceptions occur.

Detectiemethoden

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

Notities kwetsbaarheidsmapping

Rechtvaardiging : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Opmerking : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
