CVE-2022-45688· NVD / CVE Program· CNA mitre

A stack overflow in the XML.toJSONObject component of hutool-json v5.8.10 allows attackers to cause a Denial of Service (DoS) via crafted JS

Noroxi assessment

Priority: Monitor (action score 30/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 69.4% 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: cn.hutool:hutool-json (Maven) 5.8.25; org.json:json (Maven) 20230227; json-java (openSUSE:Tumbleweed) 20240303-1.1.

Low priority for now. Upgrade to cn.hutool:hutool-json (Maven) 5.8.25; org.json:json (Maven) 20230227; json-java (openSUSE:Tumbleweed) 20240303-1.1 or later.
