SECUNIA ADVISORY ID:
SA19506

VERIFY ADVISORY:
http://secunia.com/advisories/19506/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
From remote

SOFTWARE:
WebAPP 0.x
http://secunia.com/product/3829/

DESCRIPTION:
r0t has discovered some vulnerabilities in WebAPP, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Some input isn't properly sanitised before being returned to the
user. This can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an affected site.

Examples:
http://[host]/cgi-bin/index.cgi?action=[code]
http://[host]/cgi-bin/index.cgi?action=&id=[code]
http://[host]/cgi-bin/index.cgi?action=forum&board=chitchat&op=&num=[code]
http://[host]/cgi-bin/index.cgi?action=&board=[code]
http://[host]/cgi-bin/index.cgi?action=&cat=[code]
http://[host]/cgi-bin/index.cgi?action=otherarticles&writer=[code]
http://[host]/cgi-bin/index.cgi?action=&viewcat=[code]
http://[host]/cgi-bin/index.cgi?action=printtopic&id=1&curcatname=&img=[code]
http://[host]/cgi-bin/index.cgi?action=printtopic&id=1&curcatname=[code]
http://[host]/cgi-bin/mods/calendar/index.cgi?vsSD=[code]

The vulnerabilities have been confirmed in version 0.9.9.3.2. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
