The eZ Platform and Legacy are affected by an issue related to how uploaded PHP and PHAR files are handled, and consists of two parts: 1. Web server configuration, and 2. Disabling the PHAR stream wrapper. **1. WEB SERVER CONFIGURATION** The sample web server configuration in our documentation can in some cases allow the execution of uploaded PHP/PHAR code. This can be abused to allow priviledge escalation and breach of content access controls, among other things. Please ensure that your web server will not execute files in directories were files may be uploaded, such as web/var/ and ezpublish_legacy/var/ As an example, here is how you can make Apache return HTTP 403 Forbidden for a number of executable file types in your eZ Platform var directory. Please adapt it to your needs. It is then possible to enable logging of HTTP 403 in a separate log file if you wish, you could do this to see if someone is trying to abuse the server. ``` RewriteEngine On # disable .php(3) and other exten...

This Security Advisory is about a vulnerability in the way eZ Platform and eZ Publish Legacy handles file uploads, which can in the worst case lead to remote code execution (RCE), a very serious threat. An attacker would need access to uploading files to be able to exploit the vulnerability, so if you have strict controls on this and trust all who have this permission, you're not affected. On the basis of the tests we have made, we also believe the vulnerability cannot be exploited as long as our recommended vhost configuration is used. Here is the v2.5 recommendation for Nginx, as an example: https://github.com/ezsystems/ezplatform/blob/2.5/doc/nginx/vhost.template#L31 This vhost template specifies that only the file app.php in the web root is executed, while vulnerable configurations allow execution of any php file. Apache is affected in the same way as Nginx, and is also protected by using the recommended configuration. The build-in webserver in PHP stays vulnerable, as it doesn't...

The recommended Apache/Nginx virtual host configuration for eZ Platform includes a rewrite rule for blocking access to executable files in the var directory. This rule does not work when using eZ Platform Cloud (i.e. running eZ Platform on the Platform.sh cloud service). The consequence of this is that in such a setup, those executable files may be downloadable. They will not be executable, unless you have specifically configured platform.sh to allow that (which you really should not do). The severity of the download access is limited, but it's better if the platform.sh cloud setup works the same way as regular eZ Platform does. All platform.sh setups are affected. The fix adds a rule to the .platform.app.yaml configuration file, with the same effect as the rewrite rule already mentioned. After applying the fix, any attempt to access such files will fail with Access Denied. This security update is distributed via Composer as ezsystems/ezplatform 1.7.9.1, and 1.13.5.1, and 2.5.4. Th...

Nginx versions 1.25.5 and below appear to have a host header filtering validation bug that could possibly be used for malice.

This Metasploit module exploits two vulnerabilities in Palo Alto Networks PAN-OS that allow an unauthenticated attacker to create arbitrarily named files and execute shell commands. Configuration requirements are PAN-OS with GlobalProtect Gateway or GlobalProtect Portal enabled and telemetry collection on (default). Multiple versions are affected. Payloads may take up to one hour to execute, depending on how often the telemetry service is set to run.

### Summary A XSS vulnerability exists on index pages for static file handling. ### Details When using `web.static(..., show_index=True)`, the resulting index pages do not escape file names. If users can upload files with arbitrary filenames to the static directory, the server is vulnerable to XSS attacks. ### Workaround We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade. ----- Patch: https://github.com/aio-libs/aiohttp/pull/8319/files

On April 9, Twitter/X began automatically modifying links that mention "twitter.com" to redirect to "x.com" instead. But over the past 48 hours, dozens of new domain names have been registered that demonstrate how this change could be used to craft convincing phishing links -- such as fedetwitter[.]com, which is currently rendered as fedex.com in tweets.

GL-iNet MT6000 version 4.5.5 suffers from an arbitrary file download vulnerability.

A malicious ad for the popular admin tool PuTTY leads victims to a fake site that downloads malware.

### Impact The Apollo Router is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation. Affected versions are subject to a Denial-of-Service (DoS) type vulnerability. When receiving compressed HTTP payloads, affected versions of the Router evaluate the `limits.http_max_request_bytes` configuration option after the entirety of the compressed payload is decompressed. If affected versions of the Router receive highly compressed payloads, this could result in significant memory consumption while the compressed payload is expanded. ### Patches Router version 1.40.2 has a fix for the vulnerability. ### Workarounds If you are unable to upgrade, you may be able to implement mitigations at proxies or load balancers positioned in front of your Router fleet (e.g. Nginx, HAProxy, or cloud-native WAF services) by creating limits on HTTP body upload size.
