Remote Code Execution Vulnerability in EGroupware

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 has SQL Injection in Nextmatch Filter Processing

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.

WBCE CMS is Vulnerable to Privilege Escalation via Group ID Manipulation (IDOR)

WBCE CMS is a content management system. Prior to version 1.6.4, a low-privileged user in WBCE CMS can escalate their privileges to the Administrators group by manipulating the groups[] parameter in the /admin/users/save.php request. The UI restricts users to assigning only their existing group, but server-side validation is missing, allowing attackers to overwrite their group membership and obtain full administrative access. This results in a complete compromise of the CMS. This issue has been patched in version 1.6.4.
