February 2024 is likely to be remembered as one of the most turbulent months in ransomware history.

By Waqas The February 2024 Global Threat Index report released by Check Point Software Technologies Ltd. exposes the alarming vulnerability of cybersecurity worldwide.

Ubuntu Security Notice 6689-1 - It was discovered that Rack incorrectly parse some headers. An attacker could possibly use this issue to cause a denial of service.

NorthStar C2 agent version 1.0 applies insufficient sanitization on agent registration routes, allowing an unauthenticated attacker to send multiple malicious agent registration requests to the teamserver to incrementally build a functioning javascript payload in the logs web page. This cross site scripting payload can be leveraged to execute commands on NorthStar C2 agents.

### Summary More methods than expected can be called on reflex instances. Being able to call some of them has security implications. ### Details To invoke a reflex a websocket message of the following shape is sent: ```json { "target": "[class_name]#[method_name]", "args": [] } ``` The server will proceed to instantiate `reflex` using the provided `class_name` as long as it extends `StimulusReflex::Reflex`. It then attempts to call `method_name` on the instance with the provided arguments [ref](https://github.com/stimulusreflex/stimulus_reflex/blob/0211cad7d60fe96838587f159d657e44cee51b9b/app/channels/stimulus_reflex/channel.rb#L83): ```ruby method = reflex.method method_name required_params = method.parameters.select { |(kind, _)| kind == :req } optional_params = method.parameters.select { |(kind, _)| kind == :opt } if arguments.size >= required_params.size && arguments.size <= required_params.size + optional_params.size reflex.public_send(method_name, *arguments) end ``` ...

There is a potential cross-site scripting (XSS) vulnerability that can be exploited via maliciously crafted user data. This was due to improper case-sensitivity in the code that was meant to prevent these attacks. ### Impact If you render an `<a>` tag with an `href` attribute set to a user-provided link, that link could potentially execute JavaScript when clicked by another user. ```ruby a(href: user_profile) { "Profile" } ``` If you splat user-provided attributes when rendering any HTML or SVG tag, malicious event attributes could be included in the output, executing JavaScript when the events are triggered by another user. ```ruby h1(**JSON.parse(user_attributes)) ``` ### Patches Patches are [available on RubyGems](https://rubygems.org/gems/phlex) for all `1.x` minor versions. The patched versions are: - [1.9.1](https://rubygems.org/gems/phlex/versions/1.9.1) - [1.8.2](https://rubygems.org/gems/phlex/versions/1.8.2) - [1.7.1](https://rubygems.org/gems/phlex/versions/1.7.1) - [...

View CSAF 1. EXECUTIVE SUMMARY CVSS v3 7.8 ATTENTION: Low Attack Complexity Vendor: Schneider Electric Equipment: EcoStruxure Power Design Vulnerability: Deserialization of Untrusted Data 2. RISK EVALUATION Successful exploitation of this vulnerability may allow for arbitrary code execution. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Schneider Electric - EcoStruxure Power Design - Ecodial, an equipment management platform, are affected: EcoStruxure Power Design - Ecodial NL: All Versions EcoStruxure Power Design - Ecodial INT: All Versions EcoStruxure Power Design - Ecodial FR: All Versions 3.2 Vulnerability Overview 3.2.1 DESERIALIZATION OF UNTRUSTED DATA CWE-502 All versions of Schneider Electric EcoStruxure Power Design - Ecodial NL, INT, and FR deserializes untrusted data which could allow an attacker to perform code execution when a malicious project file is loaded into the application by a valid user. CVE-2024-2229 has been assigned to this vulnerability...

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.
