  script_tag(name:"insight", value:"Multiple flaws exist due to:

  - the (1) Special:MyPage, (2) Special:MyTalk, (3) Special:MyContributions, (4) Special:MyUploads, and (5) Special:AllMyUploads pages
  allow remote attackers to obtain sensitive user login information via crafted links combined with page view statistics.

  - not properly normalized IP addresses containing zero-padded octets, which might allow remote attackers to bypass intended access
  restrictions by using an IP address that was not supposed to have been allowed.

  - the User::randomPassword function generates passwords smaller than $wgMinimalPasswordLength, which makes it easier for remote
  attackers to obtain access via a brute-force attack.

  - not properly sanitized parameters when calling the cURL library, which allows remote attackers to read arbitrary files via an
  @ (at sign) character in unspecified POST array parameters.

  - the User::matchEditToken function in includes/User.php does not perform token comparison in constant time before determining if
  a debugging message should be logged, which allows remote attackers to guess the edit token and bypass CSRF protection via a timing attack,
  a different vulnerability than CVE-2015-8623.

  - the User::matchEditToken function in includes/User.php does not perform token comparison in constant time before returning, which
  allows remote attackers to guess the edit token and bypass CSRF protection via a timing attack, a different vulnerability than CVE-2015-8624.

  - Cross-site scripting (XSS) vulnerability, when is configured with a relative URL, allows remote authenticated users to inject arbitrary web
  script or HTML via wikitext, as demonstrated by a wikilink to a page named javascript:alert('XSS!').");

  have other some unspecified impact.");
