5.0
CVSS v3.1
Official Description
The cgi.rb CGI library for Ruby 1.8 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an HTTP request with a multipart MIME body that contains an invalid boundary specifier, as demonstrated using a specifier that begins with a "-" instead of "--" and contains an inconsistent ID.
Technical Analysis
CVE-2006-5467 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
