CVE-2026-12116 WRITEUP CRITICAL WRITEUP
Xerte Online Tools < 3.15.5 and < 3.14.6 - Remote Code Execution via Antivirus Binary Path Manipulation
A vulnerability in the Xerte Online Tools allows for RCE through the antivirus binary path in the tools server settings, which can be changed to a PHP interpreter, allowing an attacker to upload PHP data that will then be executed.
CVSS 9.8
CVE-2026-14261 WRITEUP CRITICAL WRITEUP
Xerte Online Tools - Remote Code Execution
A vulnerability in the Xerte Online Tools allows for authentication bypass and remote code execution via reinstallation through the /setup/ folder, enabling attackers to reinstall the service to a remote database they control.
CVSS 9.1
CVE-2021-44664 WRITEUP HIGH WRITEUP
Xerte < 3.9 - Authenticated Remote Code Execution via Language File Upload
An Authenticated Remote Code Exection (RCE) vulnerability exists in Xerte through 3.9 in website_code/php/import/fileupload.php by uploading a maliciously crafted PHP file though the project interface disguised as a language file to bypasses the upload filters. Attackers can manipulate the files destination by abusing path traversal in the 'mediapath' variable.
CVSS 8.8
CVE-2021-44664 WRITEUP HIGH WRITEUP
Xerte < 3.9 - Authenticated Remote Code Execution via Language File Upload
An Authenticated Remote Code Exection (RCE) vulnerability exists in Xerte through 3.9 in website_code/php/import/fileupload.php by uploading a maliciously crafted PHP file though the project interface disguised as a language file to bypasses the upload filters. Attackers can manipulate the files destination by abusing path traversal in the 'mediapath' variable.
CVSS 8.8
CVE-2021-44665 WRITEUP MEDIUM WRITEUP
Xerte < 3.10.3 - Path Traversal via Project File Download
A Directory Traversal vulnerability exists in the Xerte Project Xerte through 3.10.3 when downloading a project file via download.php.
CVSS 6.5
CVE-2026-34413 WRITEUP HIGH WRITEUP
Xerte Online Toolkits Missing Authentication via connector.php
Xerte Online Toolkits versions 3.15 and earlier contain a missing authentication vulnerability in the elFinder connector endpoint at /editor/elfinder/php/connector.php where an HTTP redirect to unauthenticated callers does not call exit() or die(), allowing PHP execution to continue and process the full request server-side. Unauthenticated attackers can perform file operations on project media directories including creating directories, uploading files, renaming files, duplicating files, overwriting files, and deleting files, which can be chained with path traversal and extension blocklist vulnerabilities to achieve remote code execution and arbitrary file read.
CVSS 8.6
CVE-2026-34414 WRITEUP HIGH WRITEUP
Xerte Online Toolkits Path Traversal via connector.php
Xerte Online Toolkits versions 3.15 and earlier contain a relative path traversal vulnerability in the elFinder connector endpoint at /editor/elfinder/php/connector.php where the name parameter in rename commands is not sanitized for path traversal sequences. Attackers can supply a name value containing directory traversal sequences to move files from project media directories to arbitrary locations on the filesystem, potentially overwriting application files, achieving stored cross-site scripting, or combining with other vulnerabilities to achieve unauthenticated remote code execution by moving PHP code files to the application root.
CVSS 7.1
CVE-2026-34415 WRITEUP CRITICAL WRITEUP
Xerte Online Toolkits File Upload RCE via elfinder Connector
Xerte Online Toolkits versions 3.15 and earlier contain an incomplete input validation vulnerability in the elFinder connector endpoint that fails to block PHP-executable extensions .php4 due to an incorrect regex pattern. Unauthenticated attackers can exploit this flaw combined with authentication bypass and path traversal vulnerabilities to upload malicious PHP code, rename it with a .php4 extension, and execute arbitrary operating system commands on the server.

CVE-2026-41459 WRITEUP MEDIUM WRITEUP
Xerte Online Toolkits Path Disclosure via /setup
Xerte Online Toolkits versions 3.15 and earlier contain an information disclosure vulnerability that allows unauthenticated attackers to retrieve the full server-side filesystem path of the application root. Attackers can send a GET request to the /setup page to access the exposed root_path value rendered in the HTML response, which enables exploitation of path-dependent vulnerabilities such as relative path traversal in connector.php.
