Whoogle Search is a self-hosted metasearch engine. In versions prior to 0.8.4, the `element` method in `app/routes.py` does not validate the user-controlled `src_type` and `element_url` variables and passes them to the `send` method which sends a GET request on lines 339-343 in `request.py`, which leads to a server-side request forgery. This issue allows for crafting GET requests to internal and external resources on behalf of the server. For example, this issue would allow for accessing resources on the internal network that the server has access to, even though these resources may not be accessible on the internet. This issue is fixed in version 0.8.4.

Debian Linux Security Advisory 5638-1 - It was discovered that the uv_getaddrinfo() function in libuv, an asynchronous event notification library, incorrectly truncated certain hostnames, which may result in bypass of security measures on internal APIs or SSRF attacks.

Ladder versions 0.0.1 through 0.0.21 fail to apply sufficient default restrictions on destination addresses, allowing an attacker to make GET requests to addresses that would typically not be accessible from an external context. An attacker can access private address ranges, locally listening services, and cloud instance metadata APIs.

### Summary Serveral Server-Side Request Forgery (SSRF) vulnerabilities in RSSHub allow remote attackers to use the server as a proxy to send HTTP GET requests to arbitrary targets and retrieve information in the internal network or conduct Denial-of-Service (DoS) attacks. ### Details #### `/mastodon/acct/:acct/statuses/:only_media?` https://github.com/DIYgod/RSSHub/blob/5928c5db2472e101c2f5c3bafed77a2f72edd40a/lib/routes/mastodon/acct.js#L4-L7 https://github.com/DIYgod/RSSHub/blob/5928c5db2472e101c2f5c3bafed77a2f72edd40a/lib/routes/mastodon/utils.js#L85-L105 #### `/zjol/paper/:id?` https://github.com/DIYgod/RSSHub/blob/172f6cfd2b69ea6affdbdedf61e6dde1671f3796/lib/routes/zjol/paper.js#L7-L13 #### `/m4/:id?/:category*` https://github.com/DIYgod/RSSHub/blob/172f6cfd2b69ea6affdbdedf61e6dde1671f3796/lib/routes/m4/index.js#L10-L14 ### PoC - https://rsshub.app/mastodon/acct/[email protected]%23/statuses - https://rsshub.app/zjol/paper/a6wt15r2.requestrepo.com%23 - http...

Red Hat Security Advisory 2024-1061-03 - An update is now available for Red Hat Satellite 6.13 for RHEL 8. Issues addressed include memory leak and server-side request forgery vulnerabilities.

Plus: Mozilla patches 12 flaws in Firefox, Zoom fixes seven vulnerabilities, and more critical updates from February.

With the following crawler configuration: ```python from bs4 import BeautifulSoup as Soup url = "https://example.com" loader = RecursiveUrlLoader( url=url, max_depth=2, extractor=lambda x: Soup(x, "html.parser").text ) docs = loader.load() ``` An attacker in control of the contents of `https://example.com` could place a malicious HTML file in there with links like "https://example.completely.different/my_file.html" and the crawler would proceed to download that file as well even though `prevent_outside=True`. https://github.com/langchain-ai/langchain/blob/bf0b3cc0b5ade1fb95a5b1b6fa260e99064c2e22/libs/community/langchain_community/document_loaders/recursive_url_loader.py#L51-L51 Resolved in https://github.com/langchain-ai/langchain/pull/15559

Applications that use UriComponentsBuilder to parse an externally provided URL (e.g. through a query parameter) AND perform validation checks on the host of the parsed URL may be vulnerable to a open redirect attack or to a SSRF attack if the URL is used after passing validation checks.

### Summary A lack of sanitization/check in the font path returned by php-svg-lib, in the case of a inline CSS font defined, that will be used by Cpdf to open a font will be passed to a `file_exists` call, which is sufficient to trigger metadata unserializing on a PHAR file, through the phar:// URL handler on PHP < 8.0. On other versions, it might be used as a way to get a SSRF through, for example, ftp, not restricted by authorized protocols configured on dompdf. ### Details The problem lies on the `openFont` function of the `lib/Cpdf.php` library, when the `$font` variable passed by php-svg-lib isn't checked correctly. A path is crafted through $name and $dir, which are two values that can be controlled through CSS : ``` $name = basename($font); $dir = dirname($font); [...] $metrics_name = "$name.ufm"; [...] if (!isset($this->fonts[$font]) && file_exists("$dir/$metrics_name")) { ``` Passing a font named `phar:///foo/bar/baz.phar/test` will set the value of $name to `test` and $d...

This Metasploit module chains a server side request forgery (SSRF) vulnerability (CVE-2024-21893) and a command injection vulnerability (CVE-2024-21887) to exploit vulnerable instances of either Ivanti Connect Secure or Ivanti Policy Secure, to achieve unauthenticated remote code execution. All currently supported versions 9.x and 22.x are vulnerable, prior to the vendor patch released on Feb 1, 2024. It is unknown if unsupported versions 8.x and below are also vulnerable.
