Group-Office: Authenticated Stored XSS in Administrator Context via Arbitrary Cross-User Setting Write

Group-Office is an enterprise customer relationship management and groupware tool. Prior to 26.0.25, 25.0.100, and 6.8.165, GroupOffice allows authenticated users to persist arbitrary legacy settings for any user_id via index.php?r=core/saveSetting. A separate client-side sink in the email module injects the email_font_size setting directly into JavaScript without escaping. By combining these two issues, any low-privileged authenticated user can overwrite an administrator's email_font_size setting with a JavaScript payload and trigger stored XSS in the administrator's browser when the GroupOffice web client loads views/Extjs3/modulescripts.php. This vulnerability is fixed in 26.0.25, 25.0.100, and 6.8.165.

Group-Office vulnerable to reflected XSS via Look and Feel Formatting input

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.123 and 25.0.27, a malicious JavaScript payload can be executed via the Look and Feel formatting fields. Any user can update their Look and Feel Formatting input fields, but the web application does not sanitize their input. This could result in a reflected cross-site scripting (XSS) attack. This issue has been patched in versions 6.8.123 and 25.0.27.

GroupOffice's DOM-Based XSS in all Date Input Fields Allows Arbitrary JavaScript Execution

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.119 and 25.0.20, a DOM-based Cross-Site Scripting (XSS) vulnerability exists in the GroupOffice application, allowing attackers to execute arbitrary JavaScript code in the context of the victim's browser. This can lead to session hijacking, defacement, or redirection to malicious sites. The vulnerability can be triggered by injecting a crafted payload into a parameter that is later processed unsafely in the DOM. Versions 6.8.119 and 25.0.20 contain a fix for the issue.

GroupOffice's Blind Stored XSS in Phone Number Field Enables Forced Redirect and Unauthorized Actions

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.119 and 25.0.20, a stored and blind XSS vulnerability exists in the Phone Number field of the user profile within the GroupOffice application. This allows a malicious actor to inject persistent JavaScript payloads, which are triggered in the context of another user when they view the Address Book. Successful exploitation enables actions such as forced redirects, unauthorized fetch requests, or other arbitrary JavaScript execution without user interaction. Versions 6.8.119 and 25.0.20 contain a fix for the issue.

GroupOffice vulnerable to Stored XSS in Tasks Comment Section

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.119 and 25.0.20, a persistent Cross-Site Scripting (XSS) vulnerability exists in Groupoffice's tasks comment functionality, allowing attackers to execute arbitrary JavaScript by uploading an file with a crafted filename. When administrators or other users view the task containing this malicious file, the payload executes in their browser context. The application fails to sanitize image filenames before rendering them in the comment. By uploading an image with a crafted filename containing XSS payloads, attackers can steal sensitive information. Versions 6.8.119 and 25.0.20 contain a fix for the issue.

Group-Office has stored XSS vulnerability via unsanitized filenames

Group-Office is an enterprise customer relationship management and groupware tool. In versions 6.8.148 and below, and 25.0.1 through 25.0.79, the application stores unsanitized filenames in the database, which can lead to Stored Cross-Site Scripting (XSS). Users who interact with these specially crafted file names within the Group-Office application are affected. While the scope is limited to the file-viewing context, it could still be used to interfere with user sessions or perform unintended actions in the browser. This issue is fixed in versions 6.8.149 and 25.0.80.
