Ubuntu Security Notice 6744-1 - Hugo van Kemenade discovered that Pillow was not properly performing bounds checks when processing an ICC file, which could lead to a buffer overflow. If a user or automated system were tricked into processing a specially crafted ICC file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

### Summary There is improper sanitization on Service template name which is reflecting in delete button onclick event. This value can be modified and crafted as any other javascript code. ### Vulnerable Code https://github.com/librenms/librenms/blob/a61c11db7e8ef6a437ab55741658be2be7d14d34/app/Http/Controllers/ServiceTemplateController.php#L67C23-L67C23 Above is vulnerable code line which needs to be properly sanitized ### PoC 1. Go to /services/templates 2. Enter name as `testing', '14', 'http://172.105.62.194:8000/services/templates/14');alert(1);//` 3. Submit it and try to delete it, you will see popup If you inspect element on delete button, you will notice this:- <img width="748" alt="Screenshot 2023-11-23 at 9 30 24 PM" src="https://user-images.githubusercontent.com/31764504/285260018-7672a93d-e29b-4444-8057-e6ffcb8dabfc.png"> ### Impact Cross site scripting can lead to cookie stealing or an attacker can execute any other feature using this feature.

Improper Certificate Validation vulnerability in Apache Airflow FTP Provider. The FTP hook lacks complete certificate validation in FTP_TLS connections, which can potentially be leveraged. Implementing proper certificate validation by passing context=ssl.create_default_context() during FTP_TLS instantiation is used as mitigation to validate the certificates properly. This issue affects Apache Airflow FTP Provider: before 3.7.0. Users are recommended to upgrade to version 3.7.0, which fixes the issue.

Airbnb's Allyn Stott recommends adding the Human Maturity Model (HMM) and the SABRE framework to complement MITRE ATT&CK to improve security metrics analysis.

Artificial intelligence (AI) is being introduced to just about every facet of life these days. AI is being used to develop code, communicate with customers, and write in various media. Cyber security, particularly product security is another place AI can have a significant impact. AI is being built into security tools, and, on the flip side, into the realm of exploitation. AI is now mainstream and won't be going away anytime soon, so security professionals need to learn how to best use it to help enhance the security of their systems and products.AI and its implications for securityThe term "a

Modern networks teem with machine accounts tasked with simple automated tasks yet given too many privileges and left unmonitored. Resolve that situation and you close an attack vector.

### Summary A stored XSS vulnerability in Excalidraw's web embeddable component. This allows arbitrary JavaScript to be run in the context of the domain where the editor is hosted. ### Poc Inserting an embed with the below url (can be copy/pasted onto canvas to insert as embed) will log `42` to the console: ``` https://gist.github.com/vv=v<script>console.log(42)</script> ``` ### Details There were two vectors. One rendering untrusted string as iframe's `srcdoc` without properly sanitizing against HTML injection. Second by improperly sanitizing against attribute HTML injection. This in conjunction with allowing `allow-same-origin` sandbox flag (necessary for several embeds) resulted in the XSS. Former was fixed by no longer rendering unsafe `srcdoc` content verbatim, and instead strictly parsing the supplied content and constructing the `srcdoc` manually. The latter by sanitizing properly. The `allow-same-origin` flag is now also set only in cases that require it, following the...

Keycloak was found to not properly enforce token types when validating signatures locally. An authenticated attacker could use this flaw to exchange a logout token for an access token and possibly gain access to data outside of enforced permissions.

A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. An attacker can use this flaw to construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain or possibly conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field. #### Acknowledgements: Special thanks to Axel Flamcourt for reporting this issue and helping us improve our project.

Ubuntu Security Notice 6726-3 - Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service. It was discovered that the IPv6 implementation of the Linux kernel did not properly manage route cache memory usage. A remote attacker could use this to cause a denial of service.
