Easy WP SMTP <= 1.3.9 - Missing Authorization to Arbitrary Options Update

Noroxi assessment

Priority: Plan (action score 40/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.4% (FIRST EPSS); higher than 91.3% 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: smub Easy WP SMTP – WordPress SMTP and Email Logs: Gmail, Office 365, Outlook, Custom SMTP, and more 1.3.9.1.

Add it to your regular patch cycle. Upgrade to smub Easy WP SMTP – WordPress SMTP and Email Logs: Gmail, Office 365, Outlook, Custom SMTP, and more 1.3.9.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Easy WP SMTP plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 1.3.9. This is due to missing capability checks on the admin_init() function, in addition to insufficient input validation. This makes it possible for unauthenticated attackers to modify the plugins settings and arbitrary options on the site that can be used to inject new administrative user accounts.
