EGroupware/egroupware

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.

A 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. This has been patched in versions 26.2.20260224 and 23.1.20260224.

EGroupware Vulnerable to Local File Inclusion via file:// URI in Mail Compose

EGroupware is a Web based groupware server written in PHP. A SQL Injection vulnerability exists in the core components of EGroupware prior to versions 23.1.20260113 and 26.0.20260113, 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 application. Versions 23.1.20260113 and 26.0.20260113 patch the vulnerability.

An issue was discovered in eGroupWare 17.1.20190111. A User Enumeration vulnerability exists under calendar/freebusy.php, which allows unauthenticated remote attackers to enumerate the users of web applications based on server response.

An issue was discovered in eGroupWare 17.1.20190111. A cross-site scripting Reflected (XSS) vulnerability exists in calendar/freebusy.php, which allows unauthenticated remote attackers to inject arbitrary web script or HTML into the "user" HTTP/GET parameter, which reflects its input without sanitization.

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.

An issue was discovered in eGroupWare 17.1.20190111. An Improper Password Storage vulnerability affects the setup panel of under setup/manageheader.php, which allows authenticated remote attackers with administrator credentials to read a cleartext database password.

Stored XSS vulnerability in eGroupware Community Edition before 16.1.20170922 allows an unauthenticated remote attacker to inject JavaScript via the User-Agent HTTP header, which is mishandled during rendering by the application administrator.

eGroupware before 1.8.006.20140217 allows remote attackers to conduct PHP object injection attacks, delete arbitrary files, and possibly execute arbitrary code via the (1) addr_fields or (2) trans parameter to addressbook/csv_import.php, (3) cal_fields or (4) trans parameter to calendar/csv_import.php, (5) info_fields or (6) trans parameter to csv_import.php in (a) projectmanager/ or (b) infolog/, or (7) processed parameter to preferences/inc/class.uiaclprefs.inc.php.

EGroupware Enterprise Line (EPL) before 1.1.20140505, EGroupware Community Edition before 1.8.007.20140506, and EGroupware before 14.1 beta allows remote authenticated administrators to execute arbitrary PHP code via crafted callback values to the call_user_func PHP function, as demonstrated using the newsettings[system] parameter. NOTE: this can be exploited by remote attackers by leveraging CVE-2014-2987.

Multiple cross-site request forgery (CSRF) vulnerabilities in EGroupware Enterprise Line (EPL) before 1.1.20140505, EGroupware Community Edition before 1.8.007.20140506, and EGroupware before 14.1 beta allow remote attackers to hijack the authentication of administrators for requests that (1) create an administrator user via an admin.uiaccounts.add_user action to index.php or (2) modify settings via the newsettings parameter in an admin.uiconfig.index action to index.php. NOTE: vector 2 can be used to execute arbitrary PHP code by leveraging CVE-2014-2988.

Cross-site scripting (XSS) vulnerability in phpgwapi/inc/common_functions_inc.php in eGroupware before 1.8.004.20120405 allows remote attackers to inject arbitrary web script or HTML via the menuaction parameter to etemplate/process_exec.php. NOTE: some of these details are obtained from third party information.

Open redirect vulnerability in phpgwapi/ntlm/index.php in EGroupware Enterprise Line (EPL) before 11.1.20110804-1 and EGroupware Community Edition before 1.8.001.20110805 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the forward parameter.

Cross-site scripting (XSS) vulnerability in phpgwapi/js/jscalendar/test.php in EGroupware Enterprise Line (EPL) before 11.1.20110804-1 and EGroupware Community Edition before 1.8.001.20110805 allows remote attackers to inject arbitrary web script or HTML via the lang parameter.

SQL injection vulnerability in phpgwapi/js/dhtmlxtree/samples/with_db/loaddetails.php in EGroupware Enterprise Line (EPL) before 11.1.20110804-1 and EGroupware Community Edition before 1.8.001.20110805 allows remote attackers to execute arbitrary SQL commands via the id parameter.

Directory traversal vulnerability in admin/remote.php in EGroupware Enterprise Line (EPL) before 11.1.20110804-1 and EGroupware Community Edition before 1.8.001.20110805 allows remote attackers to read arbitrary files via a ..%2f (encoded dot dot slash) in the type parameter.

phpgwapi/js/fckeditor/editor/dialog/fck_spellerpages/spellerpages/serverscripts/spellchecker.php in EGroupware 1.4.001+.002; 1.6.001+.002 and possibly other versions before 1.6.003; and EPL 9.1 before 9.1.20100309 and 9.2 before 9.2.20100309; allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) aspell_path or (2) spellchecker_lang parameters.

Cross-site scripting (XSS) vulnerability in login.php in EGroupware 1.4.001+.002; 1.6.001+.002 and possibly other versions before 1.6.003; and EPL 9.1 before 9.1.20100309 and 9.2 before 9.2.20100309; allows remote attackers to inject arbitrary web script or HTML via the lang parameter.
