HighCVSS 8.1 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 2.2% (FIRST EPSS); higher than 82.9% 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. Special conditions such as timing or configuration are required.
  • Fixed version: drupal7 (Debian:7) 7.14-2+deb7u12; drupal7 (Debian:8) 7.32-1+deb8u6; drupal/core (Packagist) 6.38, 7.43.

Low priority for now. Upgrade to drupal7 (Debian:7) 7.14-2+deb7u12; drupal7 (Debian:8) 7.32-1+deb8u6; drupal/core (Packagist) 6.38, 7.43 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The User module in Drupal 6.x before 6.38 and 7.x before 7.43 allows remote attackers to gain privileges by leveraging contributed or custom code that calls the user_save function with an explicit category and loads all roles into the array.
