Hello, we found the stored xss on forum.  
Tested on latest version 0.9.20.  
Poc:

1.  Create new topic with poll  
    
2.  XSS execute  
    

This thing is available only to administrators. This is related to the HTML Purifier settings. Administrators have more permissions than regular users.

It is needed to disable JavaScript in HTMLPurifier somehow for admins too.

<script> tags are disabled in HTMLPurifier for admins too

<script> tags are disabled in HTMLPurifier for admins too

> <script> tags are disabled in HTMLPurifier for admins too

Creating blacklists is not best practice, you should use whitelist. For example, you disable the <script> tag, but the payload <img src=x onerror=alert(1)> will work.  
For a comprehensive list, check out the DOMPurify allowlist.

Are you suggesting to make a whitelist with all possible valid options, except for the <script> tag :)?

> but the payload <img src=x onerror=alert(1)>

Really? I can't reproduce this case.

Moreover, this situation is only possible if administrator will save text with the XSS script. Regular users has more stricter HTMLPurifier settings.

New web targets for the discerning hacker

New web targets for the discerning hacker

The otherwise typically low-key month of August also brings infosec’s most renowned conference: Black Hat USA, which this year brought a word of warning for bug bounty hunters.

Dylan Ayrey, CEO of Truffle Security, cited a number of cases in which poor research and shoddy data governance has led to the leak of users’ personally identifiable information. In some cases, the data is still available long after the corresponding ticket has been closed, he warned.

“These privacy leaks in bug bounties are really common, and for every example that we can share publicly there are 100 examples that can’t be shared publicly,” said Ayrey.

In another, alleged example of suboptimal bug bounty practices CrowdStrike came under fire recently over its vulnerability disclosure process.

Pascal Zenker, a partner of Swiss security analyst service Modzero AG, claimed the Texas-based cybersecurity firm’s bug bounty program, run through HackerOne, is “NDA-ridden”, while the disclosure process “turned unprofessional in the end”.

CrowdStrike, however, defended its actions and countered that Modzero had not responded to attempts to “continue the dialogue” until six weeks had elapsed.

Among the most notable new bug bounty programs this month is Google’s latest VRP, this time focused on its open source projects, such as Golang, Angular, and Fuchsia.

Announced on August 30, the Open Source Software Vulnerability Rewards Program (OSS VRP) is designed to stem the rising tide of attacks against the software supply chain.

There were several notable payouts on existing Google VRPs, most notably when Alesandro Ortiz netted $20,000 from the tech giant – giving $4,000 to a collaborator – for unearthing a bug in the Chromium project. This allowed attackers to bypass site isolation protection through iFrames and popup windows to steal private information, read and modify cookies, and gain access to microphone and camera feeds, among other exploits.

Meanwhile, researcher ‘NDevT’ discovered two XSS vulnerabilities in Google Cloud, DevSite, and Google Play that could lead to account hijacks. They won $3,000 and $5,000 in bug bounties for their pains.

And there was a $5,000 payout for a third Google issue, with Adi Cohen discovering an XSS in AMP for Email that involved tricking Gmail’s dynamic email feature into a rendering context that the browser would not use to render a given piece of code.

Finally, in non-Google payout news, there were $4,000 and $5,000 rewards respectively for serious GitHub Pages and Reddit issues, while a Yahoo hackathon paid out $218,121 for 218 bug submissions related to its text search engine tool Vespa.

Bug Bounty Radar // The latest bug bounty programs for September 2022

OX App Suite versions 8.2 and earlier suffer from multiple cross site scripting vulnerabilities. Versions 7.10.6 and earlier suffer from a command injection vulnerability.

Product: OX App Suite  
Vendor: OX Software GmbH

Internal reference: MWB-1540  
Vulnerability type: Cross-Site Scripting (CWE-80)  
Vulnerable version: 8.2 and earlier  
Vulnerable component: backend  
Report confidence: Confirmed  
Solution status: Fixed by Vendor  
Fixed version: 7.10.5-rev44, 7.10.6-rev16, 8.2.324  
Vendor notification: 2022-03-30  
Solution date: 2022-06-10  
Public disclosure: 2022-09-01  
CVE reference: CVE-2022-29852  
CVSS: 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)

Vulnerability Details:  
The output filter mechanism for binary data can be confused by using unknown media-types. Some valid image formats were not part of our deny-list that handles potentially harmful content. Attackers can generate, upload and share malicious JS code, disguised as the BMFreehand10 or image/x-freehand image file format. This format is not detected and therefore no download gets enforced. Some browsers may attempt to render its content "inline".

Risk:  
Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface (e.g. redirecting to a third-party site). To exploit this an attacker would require access to the same OX App Suite instance and the victim to follow a hyperlink.

Solution:  
We improved content detection to include previously unknown media-types.

Internal reference: MWB-1572  
Vulnerability type: Cross-Site Scripting (CWE-80)  
Vulnerable version: 8.2 and earlier  
Vulnerable component: backend  
Report confidence: Confirmed  
Solution status: Fixed by Vendor  
Fixed version: 7.10.5-rev44, 7.10.6-rev16, 8.2.0  
Vendor notification: 2022-04-20  
Solution date: 2022-06-10  
Public disclosure: 2022-09-01  
CVE reference: CVE-2022-29853  
CVSS: 4.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

Vulnerability Details:  
Malicious HTML content at E-Mail can be abused to bypass existing content sanitization mechanisms. In this case an attacker adds junk code to force the "Show entire message" feature for huge HTML mails to generate malicious output. This involves a complex hierarchy of HTML elements and event handlers that confuse existing sanitization logic.

Risk:  
Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface (e.g. redirecting to a third-party site). To exploit this an attacker would require access to the same OX App Suite instance and the victim to follow a hyperlink.

Solution:  
We improved detection and handling of such huge HTML blocks to make sure no malicious content is returned to the client.

Internal reference: MWB-1602  
Vulnerability type: Cross-Site Scripting (CWE-80)  
Vulnerable version: 8.2 and earlier  
Vulnerable component: backend  
Report confidence: Confirmed  
Solution status: Fixed by Vendor  
Fixed version: 7.10.5-rev44, 7.10.6-rev16, 8.2.0  
Vendor notification: 2022-04-20  
Solution date: 2022-06-10  
Public disclosure: 2022-09-01  
CVE reference: CVE-2022-31468  
CVSS: 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)

Vulnerability Details:  
Content stored in attachments or OX Drive content can be requested by the client using "len" and "off" parameters. Malicious HTML content is filtered however this filter does not apply to all kind of HTML tags and allows to extract malicious code using the mentioned parameters.

Risk:  
Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface (e.g. redirecting to a third-party site). To exploit this an attacker would require access to the same OX App Suite instance and the victim to follow a hyperlink.

Solution:  
We improved detection and handling of malicious HTML content that is requested via offset and length parameters.

Internal reference: DOCS-4428  
Vulnerability type: OS Command Injection (CWE-78)  
Vulnerable version: 7.10.6 and earlier  
Vulnerable component: documentconverter  
Report confidence: Confirmed  
Solution status: Fixed by Vendor  
Fixed version: 7.10.5-rev5, 7.10.6-rev5  
Vendor notification: 2022-04-19  
Solution date: 2022-06-10  
Public disclosure: 2022-09-01  
CVE reference: CVE-2022-29851  
CVSS: 8.2 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N)

Vulnerability Details:  
In case an instance running documentconverter (readerengine) has non-default ghostscript (gs) utility installed, it may get invoked when converting EPS files that are disguised as PDF files. Ghostscript suffers from a range of vulnerabilities, some of which could be exploited via readerengine. While most are non-deterministic and cannot be used to inflict relevant damage, few may be used to execute code fragments, embedded in EPS files, on the target instance.

Risk:  
Unauthorized code may be executed with persmissions of the "open-xchange" user on readerengine instances if additional software packages like gs are installed. We urge customers to apply best-practice system hardening, which includes removal of unused components.

Solution:  
We removed a fallback to use external commands for processing EPS and other file formats.
