Directory traversal vulnerability in bin/configure in TWiki before 4.2.3, when a certain step in the installation guide is skipped, allows remote attackers to read arbitrary files via a query string containing a .. (dot dot) in the image variable, and execute arbitrary files via unspecified vectors.
Multiple cross-site scripting (XSS) vulnerabilities in lib/TWiki.pm in TWiki before 5.0.1 allow remote attackers to inject arbitrary web script or HTML via (1) the rev parameter to the view script or (2) the query string to the login script.

The localization functionality in TWiki before 5.1.3, and Foswiki 1.0.x through 1.0.10 and 1.1.x through 1.1.6, allows remote attackers to cause a denial of service (memory consumption) via a large integer in a %MAKETEXT% macro.
TWiki before 5.1.4 allows remote attackers to execute arbitrary shell commands by sending a crafted '%MAKETEXT{}%' parameter value containing Perl backtick characters.
Multiple cross-site scripting (XSS) vulnerabilities in TWiki 6.0.1 allow remote attackers to inject arbitrary web script or HTML via the (1) QUERYSTRING variable in lib/TWiki.pm or (2) QUERYPARAMSTRING variable in lib/TWiki/UI/View.pm, as demonstrated by the QUERYSTRING to do/view/Main/TWikiPreferences.
