CVE-2012-0693: Whmcs Whmcompletesolution

Medium severity, CVSS 5.0. EPSS: 0.9% chance of exploitation in the next 30 days.

submitticket.php in WHMCompleteSolution (WHMCS) 5.03 allows remote attackers to inject arbitrary code into a subject field via crafted ticket data, a different vulnerability than CVE-2011-5061. NOTE: the vendor disputes this issue, noting that some of the details overlap CVE-2011-5061, but that it "says it affects V5.0.3, and the submitticket.php file, both of which are wrong.
