SQLpage: Exposure of Sensitive Information to an Unauthorized Actor

CVE-2023-42454 is a critical-severity exposure of sensitive information to an unauthorized actor vulnerability in SQLpage from Lovasoa, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 0.11.1 as the first without the flaw, so updating SQLpage to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.74% chance of exploitation within 30 days, higher than 55% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update SQLpage to 0.11.1 or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

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.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
