CVE-2013-0235· NVD / CVE Program· CNA redhat

The XMLRPC API in WordPress before 3.5.1 allows remote attackers to send HTTP requests to intranet servers, and conduct port-scanning attack

Noroxi assessment

Priority: Plan (action score 40/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Because a ready-made attack tool exists, priority is at least “Plan”.
  • Probability of exploitation in the next 30 days: 29.5% (FIRST EPSS); higher than 98.1% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: wordpress (Debian:12) 3.5.1+dfsg-1.

Add it to your regular patch cycle. Upgrade to wordpress (Debian:12) 3.5.1+dfsg-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The XMLRPC API in WordPress before 3.5.1 allows remote attackers to send HTTP requests to intranet servers, and conduct port-scanning attacks, by specifying a crafted source URL for a pingback, related to a Server-Side Request Forgery (SSRF) issue.
