CVE-2023-6080	Written By: Jacob Paullus, Daniel McNamara, Jake Rawlins, Steven Karschnia Executive Summary Mandiant exploited flaws in the Microsoft Software... Description: Written By: Jacob Paullus, Daniel McNamara, Jake Rawlins, Steven Karschnia Executive Summary Mandiant exploited flaws in the Microsoft Software Installer (MSI) repair action of Lakeside Software's SysTrack installer to obtain arbitrary code execution. An attacker with low-privilege access to a system running the vulnerable version of SysTrack could escalate privileges locally. Mandiant responsibly disclosed this vulnerability to Lakeside Software, and the issue has been addressed in version 11.0. Introduction Building upon the insights shared in a previous Mandiant blog post, Escalating Privileges via Third-Party Windows Installers, this case study explores the ongoing challenge of securing third-party Windows installers. These vulnerabilities are rooted in insecure coding practices when creating Microsoft Software Installer (MSI) Custom Actions and can be caused by references to missing files, broken shortcuts, or insecure folder permissions. These oversights create gaps that inadvertently allow attackers the ability to escalate privileges. As covered in our previous blog post, after software is installed with an MSI file, Windows caches the MSI file in the C:\Windows\Installer folder for later use. This allows users on the system to access and use the "repair" feature, which is intended to address various issues that may be impacting the installed software. During execution of an MSI repair, several operations (such as file creation or execution) may be triggere... Source: Google Threat Intelligence February 3rd, 2025 (5 months ago)

	[github.com/cometbft/cometbft] CometBFT allows a malicious peer to make node stuck in blocksync Description: Name: ASA-2025-001: Malicious peer can disrupt node's ability to sync via blocksync Component: CometBFT Criticality: Medium (Considerable Impact; Possible Likelihood per ACMv1.2) Affected versions: <= v0.38.16, v1.0.0 Affected users: Validators, Full nodes Impact A malicious peer may be able to interfere with a node's ability to sync blocks with peers via the blocksync mechanism. In the blocksync protocol peers send their base and latest heights when they connect to a new node (A), which is syncing to the tip of a network. base acts as a lower ground and informs A that the peer only has blocks starting from height base. latest height informs A about the latest block in a network. Normally, nodes would only report increasing heights: B: {base: 100, latest: 1000} B: {base: 100, latest: 1001} B: {base: 100, latest: 1002} ... If B fails to provide the latest block, B is removed and the latest height (target height) is recalculated based on other nodes latest heights. The existing code hovewer doesn't check for the case where B first reports latest height X and immediately after height Y, where X > Y. For example: B: {base: 100, latest: 2000} B: {base: 100, latest: 1001} B: {base: 100, latest: 1002} ... A will be trying to catch up to 2000 indefinitely. Even if B disconnects, the latest height (target height) won't be recalculated because A "doesn't know where 2000" came from per see. Impact Qualification This condition requires the introduction of malicious code in the full... Source: Github Advisory Database (Go) February 3rd, 2025 (5 months ago)
	[django-unicorn] Django-Unicorn Class Pollution Vulnerability, Leading to XSS, DoS and Authentication Bypass Description: Summary Django-Unicorn is vulnerable to python class pollution vulnerability, a new type of vulnerability categorized under CWE-915. The vulnerability arises from the core functionality set_property_value, which can be remotely triggered by users by crafting appropriate component requests and feeding in values of second and third parameter to the vulnerable function, leading to arbitrary changes to the python runtime status. With this finding, so far we've found at least five ways of vulnerability exploitation, stably resulting in Cross-Site Scripting (XSS), Denial of Service (DoS), and Authentication Bypass attacks in almost every Django-Unicorn-based application. Analysis of Vulnerable Function By taking a look at the vulnerable function set_property_value located at: django_unicorn/views/action_parsers/utils.py. You can observe the functionality is responsible for modifying a property value of an object. The property is specified by a dotted form of path at the second parameter property_name, where nested reference to object is supported, and base object and the assigned value is given by the first parameter component and third parameter property_value. # https://github.com/adamghill/django-unicorn/blob/7dcb01009c3c4653b24e0fb06c7bc0f9d521cbb0/django_unicorn/views/action_parsers/utils.py#L10 def set_property_value( component, property_name, property_value ) -> None: ... property_name_parts = property_name.split(".") component_or_field = compone...
