Vulnerability Title
Authenticated RCE via Malicious eTemplate Upload in EGroupware
Vulnerability Description
In egroupware version 26.0 and earlier, 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 to arbitrary OS command execution on the server.

EGroupware 命令注入漏洞
Vulnerability Description
EGroupware是EGroupware公司开源的一个在线办公平台。 EGroupware 26.0及之前版本存在安全漏洞,该漏洞源于Widget::expand_name()方法将模板widget属性值直接传递给PHP eval()调用且反引号字符未转义,可能导致已认证管理员通过上传恶意eTemplate XML文件到VFS /etemplates挂载点实现远程代码执行。
