CVE-2023-42454: The sqlpage folder can be read by HTTP client requests · Issue #89 · lovasoa/SQLpage
SQLpage is a SQL-only webapp builder. Someone using SQLpage versions prior to 0.11.1, whose SQLpage instance is exposed publicly, with a database connection string specified in the sqlpage/sqlpage.json configuration file (not in an environment variable), with the web_root is the current working directory (the default), and with their database exposed publicly, is vulnerable to an attacker retrieving database connection information from SQLPage and using it to connect to their database directly. Version 0.11.0 fixes this issue. Some workarounds are available. Using an environment variable instead of the configuration file to specify the database connection string prevents exposing it on vulnerable versions. Using a different web root (that is not a parent of the SQLPage configuration directory) fixes the issue. One should also avoid exposing one’s database publicly.
With the browser, we can download the files in the sqlpage folder. For example, it’s possible to read the sqlpage.json configuration file. It’s a security problem. The sqlpage folder must be keep hidden.
It’s possible to set rewrite rules on the proxy side to block the download. But, I think that it will be cool to filter url in sqlpage server.
