Cross-site scripting (XSS) vulnerability in MHonArc before 2.5.14 allows remote attackers to inject arbitrary HTML into web archive pages via HTML mail messages.
MHonArc 2.5.2 and earlier does not properly filter Javascript from archived e-mail messages, which could allow remote attackers to execute script in web clients by (1) splitting the SCRIPT tag into smaller pieces, (2) including the script in a SRC argument to an IMG tag, or (3) using "&={script}" syntax.
