An arbitrary file upload vulnerability in the upload plugin of Textpattern v4.8.8 and below allows attackers to execute arbitrary code by uploading a crafted PHP file.
Textpattern CMS v4.8.7 and older vulnerability exists through Sensitive Cookie in HTTPS Session Without 'Secure' Attribute via textpattern/lib/txplib_misc.php. The secure flag is not set for txp_login session cookie in the application. If the secure flag is not set, then the cookie will be transmitted in clear-text if the user visits any HTTP URLs within the cookie's scope. An attacker may be able to induce this event by feeding a user suitable links, either directly or via another web site.
Cross-site scripting (XSS) vulnerability in Textpattern CMS before 4.5.7 allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO to setup/index.php.
Cross-site scripting (XSS) vulnerability in textarea/index.php in Textpattern (aka Txp CMS) 4.0.6 and earlier allows remote authenticated users to inject arbitrary web script or HTML via the Body parameter in an article action. NOTE: some of these details are obtained from third party information.
