Ubuntu Security Notice 6885-1 - Marc Stern discovered that the Apache HTTP Server incorrectly handled serving WebSocket protocol upgrades over HTTP/2 connections. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. Orange Tsai discovered that the Apache HTTP Server mod_proxy module incorrectly sent certain request URLs with incorrect encodings to backends. A remote attacker could possibly use this issue to bypass authentication.

### Summary There was already a reported SSRF vulnerability via file import. [https://github.com/directus/directus/security/advisories/GHSA-j3rg-3rgm-537h](https://github.com/directus/directus/security/advisories/GHSA-j3rg-3rgm-537h) It was fixed by resolving all DNS names and checking if the requested IP is an internal IP address. However it is possible to bypass this security measure and execute a SSRF using redirects. Directus allows redirects when importing file from the URL and does not check the result URL. Thus, it is possible to execute a request to an internal IP, for example to 127.0.0.1. However, it is blind SSRF, because Directus also uses response interception technique to get the information about the connect from the socket directly and it does not show a response if the IP address is internal (nice fix, by the way :) ). But the blindness does not fully mitigate the impact of the vulnerability. The blind SSRF is still exploitable in the real life scenarios, because t...

### Summary At present, when Fedify needs to retrieve an object or activity from a remote activitypub server, it makes a HTTP request to the `@id` or other resources present within the activity it has received from the web. This activity could reference an `@id` that points to an internal IP address, allowing an attacker to send request to resources internal to the fedify server's network. This applies to not just resolution of documents containing activities or objects, but also to media URLs as well. Specifically this is a [Server Side Request Forgery attack](https://owasp.org/www-community/attacks/Server_Side_Request_Forgery). You can learn more about SSRF attacks via [CWE-918](https://cwe.mitre.org/data/definitions/918.html) ### Details When Fedify makes a request at runtime via the DocLoader [1] [2], the `fetch` API does not first check the URI's to assert that it resolve to a public IP address. Additionally, any downstream software of Fedify that may fetch data from URIs co...

A vulnerability was found in ShopXO up to 6.1.0. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file `extend/base/Uploader.php`. The manipulation of the argument source leads to server-side request forgery. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-270367. NOTE: The original disclosure confuses CSRF with SSRF.

308 different models of Sharp Multi-Function Printers (MFP) are vulnerable to 18 different vulnerabilities including remote code execution, local file inclusion, credential disclosure, and more.

Red Hat Security Advisory 2024-4247-03 - An update for libuv is now available for Red Hat Enterprise Linux 8. Issues addressed include a server-side request forgery vulnerability.

### Impact Before deserializing CycloneDX Bill of Materials in XML format, _cyclonedx-core-java_ leverages XPath expressions to determine the schema version of the BOM. The `DocumentBuilderFactory` used to evaluate XPath expressions was not configured securely, making the library vulnerable to XML External Entity (XXE) injection. XXE injection can be exploited to exfiltrate local file content, or perform Server Side Request Forgery (SSRF) to access infrastructure adjacent to the vulnerable application. ### PoC ```java import org.cyclonedx.parsers.XmlParser; class Poc { public static void main(String[] args) { // Will throw org.cyclonedx.exception.ParseException: java.net.ConnectException: Connection refused new XmlParser().parse(""" <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE bom [<!ENTITY % sp SYSTEM "https://localhost:1010/does-not-exist/file.dtd"> %sp;]> <bom xmlns="http://cyclonedx.org/schema/bom/1.5"/> ...

An open redirect vulnerability exists in the gradio-app/gradio, affecting the latest version. The vulnerability allows an attacker to redirect users to arbitrary websites, which can be exploited for phishing attacks, Cross-site Scripting (XSS), Server-Side Request Forgery (SSRF), amongst others. This issue is due to improper validation of user-supplied input in the handling of URLs. Attackers can exploit this vulnerability by crafting a malicious URL that, when processed by the application, redirects the user to an attacker-controlled web page.

Summary On May 9, 2024, Microsoft successfully addressed multiple vulnerabilities within the Azure Machine Learning (AML) service, which were initially discovered by security research firms Wiz and Tenable. These vulnerabilities, which included Server-Side Request Forgeries (SSRF) and a path traversal vulnerability, posed potential risks for information exposure and service disruption via Denial-of-Service (DOS).

Red Hat Security Advisory 2024-3708-03 - Red Hat build of Apache Camel 3.20.6 for Spring Boot release and security update is now available. Issues addressed include denial of service and server-side request forgery vulnerabilities.
