ImpressCMS Authenticated RCE via PHP Custom Tag eval()

ImpressCMS contains an authenticated remote code execution vulnerability in the custom tag module that allows authenticated administrators to execute arbitrary PHP code by storing a malicious payload in a custom tag with PHP type enabled. The application decodes HTML-encoded content via undoHtmlSpecialChars() before passing it to eval() in the renderWithPhp() method, bypassing HTML Purifier sanitization, and the payload is triggered on every frontend page load through the preload event system.

ImpressCMS 1.4.2 Remote Code Execution via Autotasks

ImpressCMS 1.4.2 contains a remote code execution vulnerability in the autotasks administrative interface that allows authenticated attackers to execute arbitrary PHP code by injecting malicious code into the sat_code parameter. Attackers can authenticate, submit a POST request to /modules/system/admin.php?fct=autotasks&op=mod with crafted sat_code containing PHP commands, which creates an executable file that accepts arbitrary commands via GET parameters.

Cross-site scripting (XSS) vulnerability in the userranks feature in modules/system/admin.php in ImpressCMS 1.0.2 final allows remote attackers to inject arbitrary web script or HTML via the rank_title parameter. NOTE: some of these details are obtained from third party information.

Multiple unspecified vulnerabilities in ImpressCMS 1.0 have unknown impact and attack vectors, related to modules/admin.php and "a few files."

Session fixation vulnerability in Social ImpressCMS before 1.1.1 RC1 allows remote attackers to hijack web sessions by setting the PHPSESSID parameter.

ImpressCMS 1.3.11 SQL Injection via bid Parameter

ImpressCMS 1.3.11 contains a time-based blind SQL injection vulnerability that allows authenticated attackers to manipulate database queries by injecting SQL code through the 'bid' parameter. Attackers can send POST requests to the admin.php endpoint with malicious 'bid' values containing SQL commands to extract sensitive database information.

ImpressCMS 1.4.4 - Unrestricted File Upload

ImpressCMS 1.4.4 contains a file upload vulnerability with weak extension sanitization that allows attackers to upload potentially malicious files. Attackers can bypass file upload restrictions by using alternative file extensions .php2.php6.php7.phps.pht to execute arbitrary PHP code on the server.

Absolute path traversal vulnerability in htdocs/libraries/image-editor/image-edit.php in ImpressCMS before 1.3.6 allows remote attackers to delete arbitrary files via a full pathname in the image_path parameter in a cancel action.

Cross-site scripting (XSS) vulnerability in modules/system/admin.php in ImpressCMS 1.3.6.1 allows remote attackers to inject arbitrary web script or HTML via the query parameter in a listimg action.

Multiple cross-site scripting (XSS) vulnerabilities in ImpressCMS 1.2.x before 1.2.7 Final and 1.3.x before 1.3.1 Final allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) notifications.php, (2) modules/system/admin/images/browser.php, and (3) modules/content/admin/content.php.

Directory traversal vulnerability in edituser.php in ImpressCMS 1.2.x before 1.2.7 Final and 1.3.x before 1.3.1 Final allows remote authenticated users to include and execute arbitrary local files via a .. (dot dot) in the icmsConfigPlugins[sanitizer_plugins][] parameter.

Cross-site scripting (XSS) vulnerability in modules/content/admin/content.php in ImpressCMS 1.2.3 Final, and possibly other versions before 1.2.4, allows remote attackers to inject arbitrary web script or HTML via the quicksearch_ContentContent parameter.

SQL injection vulnerability in ImpressCMS before 1.2.3 RC2 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

A cross-site scripting (XSS) vulnerability in ImpressCMS v1.4.5 and before allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the smile_code parameter of the component /editprofile.php.

SQL Injection in ImpressCMS 1.4.3 and earlier allows remote attackers to inject into the code in unintended way, this allows an attacker to read and modify the sensitive information from the database used by the application. If misconfigured, an attacker can even upload a malicious web shell to compromise the entire system.

ImpressCMS before 1.4.2 allows unauthenticated remote code execution via ...../// directory traversal in origName or imageName, leading to unsafe interaction with the CKEditor processImage.php script. The payload may be placed in PHP_SESSION_UPLOAD_PROGRESS when the PHP installation supports upload_progress.

Cross-site scripting (XSS) in modules/content/admin/content.php in ImpressCMS profile 1.4.2 allows remote attackers to inject arbitrary web script or HTML parameters through the "Display Name" field.

ImpressCMS before 1.4.3 allows libraries/image-editor/image-edit.php image_temp Directory Traversal.

ImpressCMS before 1.4.3 has plugins/preloads/autologin.php type confusion with resultant Authentication Bypass (!= instead of !==).

ImpressCMS before 1.4.3 allows include/findusers.php groups SQL Injection.
