Synopsis ========
DokuWiki is vulnerable to a cross-site scripting attack.
Background ==========
DokuWiki is a simple to use wiki aimed at creating documentation.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/dokuwiki < 20061106 >=3D 20061106
Description ===========
DokuWiki does not sanitize user input to the GET variable 'media' in the fetch.php file.
Impact ======
An attacker could entice a user to click a specially crafted link and inject CRLF characters into the variable. This would allow the creation of new lines or fields in the returned HTTP Response header, which would permit the attacker to execute arbitrary scripts in the context of the user's browser.
Workaround ==========
Replace the following line in lib/exe/fetch.php: $MEDIA =3D getID('media',false); // no cleaning - maybe external
with $MEDIA =3D preg_replace('/[\x00-\x1F]+/s','',getID('media',false));
Resolution ==========
All DokuWiki users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dwww-apps/dokuwiki-20061106"
References ==========
