CVE-2023-33968: Missing Access Control allows User to move and duplicate tasks in Kanboard

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: 0.38% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: kanboard kanboard 1.2.30.

Low priority for now. Upgrade to kanboard kanboard 1.2.30 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Kanboard is open source project management software that focuses on the Kanban methodology. Versions prior to 1.2.30 are subject to a missing access control vulnerability that allows a user with low privileges to create or transfer tasks to any project within the software, even if they have not been invited or the project is personal. The vulnerable features are `Duplicate to project` and `Move to project`, which both utilize the `checkDestinationProjectValues()` function to check his values. This issue has been addressed in version 1.2.30. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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.
