NocoBase: SQL injection in /api/myInAppChannels:list filter to PG-superuser RCE

Noroxi assessment

Priority: Plan (action score 40/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.89% (FIRST EPSS); higher than 58.6% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: nocobase nocobase 2.0.61.

Add it to your regular patch cycle. Upgrade to nocobase nocobase 2.0.61 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to 2.0.61, NocoBase @nocobase/plugin-notification-in-app-message exposed GET /api/myInAppChannels:list, where the filter[latestMsgReceiveTimestamp][$lt] value was inserted into a Sequelize.literal() template string without escaping or parameter binding, allowing a signed-up authenticated user to run stacked PostgreSQL statements and potentially execute commands with COPY ... TO PROGRAM. This vulnerability is fixed in 2.0.61.
