CVE-2023-33229: SolarWinds Platform Incorrect Input Neutralization Vulnerability

Noroxi assessment

Priority: Monitor (action score 14/100)

  • 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: 0.77% (FIRST EPSS); higher than 55.7% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: SolarWinds SolarWinds Platform 2023.3.

Low priority for now. Upgrade to SolarWinds SolarWinds Platform 2023.3 or later.
