CVE-2022-35978: Lua sandbox escape from mod in Minetest

Noroxi assessment

Priority: Plan (action score 41/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.1% (FIRST EPSS); higher than 87.7% of all records.
  • 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.
  • Fixed version: minetest (Debian:12) 5.5.0+dfsg+~1.9.0mt4+dfsg-2; minetest (openSUSE:Leap 15.3) 5.6.0-bp154.2.3.5; luanti (openSUSE:Tumbleweed) 5.11.0-1.1.
  • Severity is disputed: the assigning authority (CNA) scores it 7.7, NVD 10.0.

Add it to your regular patch cycle. Upgrade to minetest (Debian:12) 5.5.0+dfsg+~1.9.0mt4+dfsg-2; minetest (openSUSE:Leap 15.3) 5.6.0-bp154.2.3.5; luanti (openSUSE:Tumbleweed) 5.11.0-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Minetest is a free open-source voxel game engine with easy modding and game creation. In **single player**, a mod can set a global setting that controls the Lua script loaded to display the main menu. The script is then loaded as soon as the game session is exited. The Lua environment the menu runs in is not sandboxed and can directly interfere with the user's system. There are currently no known workarounds.

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.
