class.upload.php in verot.net class.upload through 1.0.3 and 2.x through 2.0.4, as used in the K2 extension for Joomla! and other products, omits .pht from the set of dangerous file extensions, a similar issue to CVE-2019-19576.
class.upload.php in verot.net class.upload before 1.0.3 and 2.x before 2.0.4, as used in the K2 extension for Joomla! and other products, omits .phar from the set of dangerous file extensions.
The K2 component 2.8.0 for Joomla! has Incorrect Access Control with directory traversal, allowing an attacker to download arbitrary files, as demonstrated by a view=media&task=connector&cmd=file&target=l1_../configuration.php&download=1 request. The specific pathname ../configuration.php should be base64 encoded for a valid attack. NOTE: the vendor disputes this issue because only files under the media-manager path can be downloaded, and the documentation indicates that sensitive information does not belong there. Nonetheless, 2.8.1 has additional blocking of .php downloads
Directory traversal vulnerability in includes/download.php in the JoomlaWorks AllVideos (Jw_allVideos) plugin 3.0 through 3.2 for Joomla! allows remote attackers to read arbitrary files via a ./../.../ (modified dot dot) in the file parameter.
SQL injection vulnerability in the K2 (com_k2) component 1.0.1 Beta and earlier for Joomla! allows remote attackers to execute arbitrary SQL commands via the category parameter in an itemlist action to index.php.
