CVE-2016-7964: SSRF vulnerability

A SSRF vulnerability was found in dokuwiki. The sendRequest method in HTTPClient Class(In file: /inc/HTTPClient.php) has no restrict to access private network, such as, 10.0.0.1/8, 172.16.0.0/12, 192.168.0.0/16. This allows user to scan port of internal network.

CVE-2016-7965: Password reset address spoof vulnerability

DokuWiki uses $_SERVER[HTTP_HOST] to be a part of the password reset address. This can lead to phishing attacks because of the modification of the site's links. (A remote unauthenticated attacker can change the host in reset password address.)
The vulnerability can be triggered only if the Host header is not part of the web server routing process (e.g. if several domains are served by the same web server).

Comment 3 Andrej Nemec 2017-08-31 09:20:43 EDT
CVE-2017-12979

DokuWiki through 2017-02-19c has stored XSS when rendering a malicious language name in a code element, in /inc/parser/xhtml.php. An attacker can create or edit a wiki with this element to trigger JavaScript execution.

CVE-2017-12980

DokuWiki through 2017-02-19c has stored XSS when rendering a malicious RSS or Atom feed, in /inc/parser/xhtml.php. An attacker can create or edit a wiki that uses RSS or Atom data from an attacker-controlled server to trigger JavaScript execution. The JavaScript can be in an author field, as demonstrated by the dc:creator element.

Comment 4 Andrej Nemec 2018-02-05 09:21:16 EST
CVE-2017-18123

The call parameter of /lib/exe/ajax.php in DokuWiki through 2017-02-19e does not properly encode user input, which leads to a reflected file download vulnerability, and allows remote attackers to run arbitrary programs.
