The function processes image URLs embedded in an HTML email body without validating or restricting URI schemes. The check !str_starts_with($myUrl, 'http') evaluates to true for file:// URIs, causing file_get_contents($basedir . urldecode($myUrl)) to read arbitrary files from the server filesystem and embed them as inline MIME attachments in outgoing email. str_starts_with('file:///etc/passwd', 'http') → false !false → true // api/src/Mail.php foreach($images[2] as $i => $url) { //$isData = false; $basedir = $data …

An authenticated administrator can achieve OS-level Remote Code Execution (RCE) by uploading a malicious eTemplate XML file (.xet) to the VFS /etemplates mount. The Widget::expand_name() method passes template widget attribute values directly into a PHP eval() call with only double-quote escaping applied - backtick characters are not escaped. In PHP, backticks inside a double-quoted eval() string execute shell commands. This allows an admin-level user to escalate from web application access …

A critical vulnerability has been identified in EGroupware that may lead to Remote Code Execution (RCE). The issue allows an authenticated attacker to execute arbitrary commands on the server. If user self-registration is enabled, the vulnerability may be exploitable without prior authentication. The vulnerability stems from improper authorization checks combined with a file write primitive and an arbitrary file read vulnerability, which together enable full system compromise.

Critical Authenticated SQL Injection in Nextmatch Widget Filter Processing A critical SQL Injection vulnerability exists in the core components of EGroupware, specifically in the Nextmatch filter processing. The flaw allows authenticated attackers to inject arbitrary SQL commands into the WHERE clause of database queries. This is achieved by exploiting a PHP type juggling issue where JSON decoding converts numeric strings into integers, bypassing the is_int() security check used by the …

EGroupware before 23.1.20240624 mishandles an ORDER BY clause. This leads to json.php menuaction=EGroupware\Api\Etemplate\Widget\Nextmatch::ajax_get_rows sort.id SQL injection by authenticated users for Address Book or InfoLog sorting.
