CVE-2023-40570: Datasette 1.0 alpha series leaks names of databases and tables to unauthenticated users

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.55% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: simonw datasette 1.0a4.

Low priority for now. Upgrade to simonw datasette 1.0a4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Datasette is an open source multi-tool for exploring and publishing data. This bug affects Datasette instances running a Datasette 1.0 alpha - 1.0a0, 1.0a1, 1.0a2 or 1.0a3 - in an online accessible location but with authentication enabled using a plugin such as datasette-auth-passwords. The `/-/api` API explorer endpoint could reveal the names of both databases and tables - but not their contents - to an unauthenticated user. Datasette 1.0a4 has a fix for this issue. This will block access to the API explorer but will still allow access to the Datasette read or write JSON APIs, as those use different URL patterns within the Datasette `/database` hierarchy. This issue is patched in version 1.0a4.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
