WordPress before 2.0.5 does not properly store a profile containing a string representation of a serialized object, which allows remote authenticated users to cause a denial of service (application crash) via a string that represents a (1) malformed or (2) large serialized object, because the object triggers automatic unserialization for display.
Multiple directory traversal vulnerabilities in plugins/wp-db-backup.php in WordPress before 2.0.5 allow remote authenticated users to read or overwrite arbitrary files via directory traversal sequences in the (1) backup and (2) fragment parameters in a GET request.
WordPress 2.0.2 through 2.0.5 allows remote attackers to obtain sensitive information via a direct request for (1) 404.php, (2) akismet.php, (3) archive.php, (4) archives.php, (5) attachment.php, (6) blogger.php, (7) comments.php, (8) comments-popup.php, (9) dotclear.php, (10) footer.php, (11) functions.php, (12) header.php, (13) hello.php, (14) wp-content/themes/default/index.php, (15) links.php, (16) livejournal.php, (17) mt.php, (18) page.php, (19) rss.php, (20) searchform.php, (21) search.php, (22) sidebar.php, (23) single.php, (24) textpattern.php, (25) upgrade-functions.php, (26) upgrade-schema.php, or (27) wp-db-backup.php, which reveal the path in various error messages. NOTE: another researcher has disputed the details of this report, stating that version 2.0.5 does not exist. NOTE: the admin-footer.php, admin-functions.php, default-filters.php, edit-form-advanced.php, edit-link-form.php, edit-page-form.php, kses.php, locale.php, rss-functions.php, template-loader.php, and wp-db.php vectors are already covered by CVE-2006-0986. The edit-form-comment.php, vars.php, and wp-settings.php vectors are already covered by CVE-2005-4463. The menu-header.php vector is already covered by CVE-2005-2110.
Multiple unspecified vulnerabilities in WordPress before 2.0.4 have unknown impact and remote attack vectors. NOTE: due to lack of details, it is not clear how these issues are different from CVE-2006-3389 and CVE-2006-3390, although it is likely that 2.0.4 addresses an unspecified issue related to "Anyone can register" functionality (user registration for guests).
index.php in WordPress 2.0.3 allows remote attackers to obtain sensitive information, such as SQL table prefixes, via an invalid paged parameter, which displays the information in an SQL error message. NOTE: this issue has been disputed by a third party who states that the issue does not leak any target-specific information.
WordPress 2.0.3 allows remote attackers to obtain the installation path via a direct request to various files, such as those in the (1) wp-admin, (2) wp-content, and (3) wp-includes directories, possibly due to uninitialized variables.
