Kod programskog paketa MHonArc otkriveno je nekoliko sigurnosnih propusta. Radi se o programskom alatu namijenjenom pretvaranju poruka elektroničke pošte u HTML format. Uočeni nedostaci posljedica su XSS (eng. Cross-site scripting) ranjivosti u skripti "mhtxthtml.pl" te ranjivosti vezane uz gniježđenje početaka HTML-ovih oznaka. Udaljeni napadači ove nepravilnosti mogu iskoristiti za pokretanje napada uskraćivanja usluge te ubacivanje proizvoljnih web skripti preko posebno oblikovanih početnih i završnih oznaka (eng. tag). Korisnicima se preporuča primjena objavljenih nadogradnji koje uklanjaju navedene nedostatke.

Problem Description:
Multiple vulnerabilities has been found and corrected in MHonArc:
MHonArc 2.6.16 allows remote attackers to cause a denial of service
(CPU consumption) via start tags that are placed within other start
tags, as demonstrated by a
<bo<bo<bo<bo<body>dy>dy>dy>dy> sequence,
a different vulnerability than CVE-2010-4524 (CVE-2010-1677).
Cross-site scripting (XSS) vulnerability in lib/mhtxthtml.pl in
MHonArc 2.6.16 allows remote attackers to inject arbitrary web script
or HTML via a malformed start tag and end tag for a SCRIPT element,
as demonstrated by <scr<body>ipt> and </scr<body>ipt>
sequences
(CVE-2010-4524).
