## What is CVE-2023-37270?

CVE-2023-37270 is a high-severity SQL injection vulnerability in Piwigo Piwigo, published on 7 Jul 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Piwigo is open source photo gallery software. Prior to version 13.8.0, there is a SQL Injection vulnerability in the login of the administrator screen. The SQL statement that acquires the HTTP Header `User-Agent` is vulnerable at the endpoint that records user information when logging in to the administrator screen. It is possible to execute arbitrary SQL statements. Someone who wants to exploit the vulnerability must be log in to the administrator screen, even with low privileges. Any SQL statement can be executed. Doing so may leak information from the database. Version 13.8.0 contains a fix for this issue. As another mitigation, those who want to execute a SQL statement verbatim with user-enterable parameters should be sure to escape the parameter contents appropriately.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
