CVE-2023-4450: jeecgboot JimuReport Template injection

Noroxi assessment

Priority: Plan (action score 42/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 11.5% (FIRST EPSS); higher than 96% 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: jeecgboot JimuReport 1.6.1.
  • Severity is disputed: the assigning authority (CNA) scores it 6.3, NVD 9.8.

Add it to your regular patch cycle. Upgrade to jeecgboot JimuReport 1.6.1 or later.
