Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.37% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Piwigo Piwigo 16.3.0.

Low priority for now. Upgrade to Piwigo Piwigo 16.3.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Piwigo is an open source photo gallery application for the web. Prior to version 16.3.0, a SQL Injection vulnerability exists in the pwg.users.getList Web Service API method. The filter parameter is directly concatenated into a SQL query without proper sanitization, allowing authenticated administrators to execute arbitrary SQL commands. This issue has been patched in version 16.3.0.
