Description Andrej Nemec 2017-05-04 14:36:10 UTC
A vulnerability was found in the SyntaxHighlight MediaWiki extension.
Using this vulnerability it is possible for an anonymous attacker to
pass arbitrary options to the Pygments library. By specifying specially
crafted options, it is possible for an attacker to trigger a (stored)
Cross-Site Scripting condition. In addition, it allows the creating of
arbitrary files containing user-controllable data. Depending on the
server configuration, this can be used by an anonymous attacker to
execute arbitrary PHP code.
