A vulnerability was detected in e107 CMS up to 2.3.3. This impacts an unknown function of the file /e107_admin/image.php?mode=main&action=avatar of the component Avatar Handler. Performing manipulation of the argument multiaction[] results in path traversal. It is possible to initiate the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
e107 CMS thru 2.3.3 are vulnerable to insecure deserialization in the `install.php` script. The script processes user-controlled input in the `previous_steps` POST parameter using `unserialize(base64_decode())` without validation, allowing attackers to craft malicious serialized data. This could lead to remote code execution, arbitrary file operations, or denial of service, depending on available PHP object gadgets in the codebase.
fpw.php in e107 through 1.0.4 does not check the user_ban field, which makes it easier for remote attackers to reset passwords by sending a pwsubmit request and leveraging access to the e-mail account of a banned user.
Cross-site scripting (XSS) vulnerability in e107_plugins/content/handlers/content_preset.php in e107 before 1.0.3 allows remote attackers to inject arbitrary web script or HTML via the query string.
The cross-site request forgery (CSRF) protection mechanism in e107 before 0.7.23 uses a predictable random token based on the creation date of the administrator account, which allows remote attackers to hijack the authentication of administrators for requests that add new users via e107_admin/users.php.
Static code injection vulnerability in install_.php in e107 CMS 0.7.24 and probably earlier versions, when the installation script is not removed, allows remote attackers to inject arbitrary PHP code into e107_config.php via a crafted MySQL server name.
Cross-site scripting (XSS) vulnerability in e107 0.7.22 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
Cross-site scripting (XSS) vulnerability in submitnews.php in e107 before 0.7.23 allows remote attackers to inject arbitrary web script or HTML via the submitnews_title parameter, a different vector than CVE-2008-6208. NOTE: some of these details are obtained from third party information. NOTE: this might be the same as CVE-2009-4083.1 or CVE-2011-0457.
Incomplete blacklist vulnerability in usersettings.php in e107 0.7.20 and earlier allows remote attackers to conduct SQL injection attacks via the loginname parameter.
