Cross-site scripting (XSS) vulnerability in the nBill (com_nbill) component 2.3.2 for Joomla! allows remote attackers to inject arbitrary web script or HTML via the message parameter in an income action to administrator/index.php.
plugins/system/highlight/highlight.php in Joomla! 3.0.x through 3.0.2 and 2.5.x through 2.5.8 allows attackers to unserialize arbitrary PHP objects to obtain sensitive information, delete arbitrary directories, conduct SQL injection attacks, and possibly have other impacts via the highlight parameter. Note: it was originally reported that this issue only allowed attackers to obtain sensitive information, but later analysis demonstrated that other attacks exist.
SQL injection vulnerability in the JV Comment (com_jvcomment) component before 3.0.3 for Joomla! allows remote authenticated users to execute arbitrary SQL commands via the id parameter in a comment.like action to index.php.
Cross-site scripting (XSS) vulnerability in the JoomShopping (com_joomshopping) component before 4.3.1 for Joomla! allows remote attackers to inject arbitrary web script or HTML via the user_name parameter to index.php.
Akeeba Restore (restore.php), as used in Joomla! 2.5.4 through 2.5.25, 3.x through 3.2.5, and 3.3.0 through 3.3.4; Akeeba Backup for Joomla! Professional 3.0.0 through 4.0.2; Backup Professional for WordPress 1.0.b1 through 1.1.3; Solo 1.0.b1 through 1.1.2; Admin Tools Core and Professional 2.0.0 through 2.4.4; and CMS Update 1.0.a1 through 1.0.1, when performing a backup or update for an archive, does not delete parameters from $_GET and $_POST when it is cleansing $_REQUEST, but later accesses $_GET and $_POST using the getQueryParam function, which allows remote attackers to bypass encryption and execute arbitrary code via a command message that extracts a crafted archive.
XCloner plugin version 3.1.1 for WordPress and 3.5.1 for Joomla! suffers from arbitrary command execution, MySQL password disclosure, database backups exposed, unauthenticated remote access, and various other vulnerabilities.
Multiple SQL injection vulnerabilities in Joomla! before 1.0.4 allow remote attackers to execute arbitrary SQL commands via the (1) Itemid variable in the Polls modules and (2) multiple unspecified methods in the mosDBTable class.
The vCard functions in Joomla! 1.0.5 use predictable sequential IDs for vcards and do not restrict access to them, which allows remote attackers to obtain valid e-mail addresses to conduct spam attacks by modifying the contact_id parameter to index2.php.
Multiple unspecified vulnerabilities in the (1) publishing component, (2) Contact Component, (3) TinyMCE Compressor, and (4) other components in Joomla! 1.0.5 and earlier have unknown impact and attack vectors.
feedcreator.class.php (aka the syndication component) in Joomla! 1.0.7 allows remote attackers to obtain sensitive information via a "/" (slash) in the feed parameter to index.php, which reveals the path in an error message.
feedcreator.class.php (aka the syndication component) in Joomla! 1.0.7 allows remote attackers to cause a denial of service (stressed file cache) by creating many files via filenames in the feed parameter to index.php.
The cross-site scripting (XSS) countermeasures in class.inputfilter.php in Joomla! 1.0.7 allow remote attackers to cause a denial of service via a crafted mosmsg parameter to index.php with a malformed sequence of multiple tags, as demonstrated using "<<>AAA<><>", possibly due to nested or empty tags.
Joomla! 1.0.7 and earlier allows attackers to bypass intended access restrictions and gain certain privileges via certain attack vectors related to the (1) Weblink, (2) Polls, (3) Newsfeeds, (4) Weblinks, (5) Content, (6) Content Section, (7) Content Category, (8) Contact items, or (9) Contact Search, (10) Content Search, (11) Newsfeed Search, or (12) Weblink Search.
The com_rss option (rss.php) in (1) Mambo and (2) Joomla! allows remote attackers to cause a denial of service (disk consumption and possibly web-server outage) via multiple requests with different values of the feed parameter.
