Description

• CVE-2017-0361 (information disclosure)

MediaWiki before 1.29.2 may leak passwords in plaintext. API parameters
may now be marked as “sensitive” to keep their values out of the logs.

• CVE-2017-8808 (cross-site scripting)

MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2
has XSS when the $wgShowExceptionDetails setting is false and the
browser sends non-standard URL escaping.

• CVE-2017-8809 (url request injection)

api.php in MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x
before 1.29.2 has a Reflected File Download vulnerability.

• CVE-2017-8810 (information disclosure)

MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before
1.29.2, when a private wiki is configured, provides different error
messages for failed login attempts depending on whether the username
exists, which allows remote attackers to enumerate account names and
conduct brute-force attacks via a series of requests.

• CVE-2017-8811 (cross-site scripting)

The implementation of raw message parameter expansion in MediaWiki
before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 allows
HTML mangling attacks.

• CVE-2017-8812 (insufficient validation)

MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2
allows remote attackers to inject > (greater than) characters via the
id attribute of a headline.

• CVE-2017-8814 (cross-site scripting)

The language converter in MediaWiki before 1.27.4, 1.28.x before
1.28.3, and 1.29.x before 1.29.2 allows attackers to replace text
inside tags via a rule definition followed by “a lot of junk.”

• CVE-2017-8815 (cross-site scripting)

The language converter in MediaWiki before 1.27.4, 1.28.x before
1.28.3, and 1.29.x before 1.29.2 allows attribute injection attacks via
glossary rules.

Impact

A remote attacker is able to perform a cross-side scripting attack by
injecting javascript into the site, disclose information or perform a
reflected file download attack.
