Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a SQL Injection issue in the Piwigo photo gallery application, specifically in the pwg.users.getList Web Service API method. Before version 16.3.0, the filter parameter is directly concatenated into a SQL query without proper sanitization. This allows authenticated administrators to execute arbitrary SQL commands on the database.
How can this vulnerability impact me? :
An attacker who is an authenticated administrator can exploit this vulnerability to execute arbitrary SQL commands. This can lead to unauthorized data access, data modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the application’s data.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should upgrade Piwigo to version 16.3.0 or later, where the SQL Injection issue in the pwg.users.getList Web Service API method has been patched.
Additionally, ensure that only trusted authenticated administrators have access to this API method to reduce the risk of exploitation.
