Many GitHub users this week received a novel phishing email warning of critical security holes in their code. Those who clicked the link for details were asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware. While it's unlikely that many programmers fell for this scam, it's notable because less targeted versions of it are likely to be far more successful against the average Windows user.

Hi, Rspack|Webpack developer team! ## Summary We discovered a DOM Clobbering vulnerability in Webpack’s AutoPublicPathRuntimeModule. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. We found the real-world exploitation of this gadget in the Canvas LMS which allows XSS attack happens through an javascript code compiled by Webpack (the vulnerable part is from Webpack). We believe this is a severe issue. If Webpack’s code is not resilient to DOM Clobbering attacks, it could lead to significant security vulnerabilities in any web application using Webpack-compiled code. ## Details ### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in t...

A previously undocumented malware called SambaSpy is exclusively targeting users in Italy via a phishing campaign orchestrated by a suspected Brazilian Portuguese-speaking threat actor. "Threat actors usually try to cast a wide net to maximize their profits, but these attackers are focused on just one country," Kaspersky said in a new analysis. "It's likely that the attackers are testing the

EXECUTIVE SUMMARY CVSS v4 9.3 ATTENTION: Exploitable remotely/low attack complexity Vendor: MegaSys Computer Technologies Equipment: Telenium Online Web Application Vulnerability: Improper Input Validation 2. RISK EVALUATION Successful exploitation of this vulnerability could allow an attacker to inject arbitrary Perl code through a crafted HTTP request, leading to remote code execution on the server. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following MegaSys Computer Technologies products are affected: Telenium Online Web Application: versions 8.3 and prior 3.2 Vulnerability Overview 3.2.1 IMPROPER INPUT VALIDATION CWE-20 Telenium Online Web Application is vulnerable due to a Perl script that is called to load the login page. Due to improper input validation, an attacker can inject arbitrary Perl code through a crafted HTTP request, leading to remote code execution on the server. CVE-2024-6404 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.8 ha...

GitLab has released patches to address a critical flaw impacting Community Edition (CE) and Enterprise Edition (EE) that could result in an authentication bypass. The vulnerability is rooted in the ruby-saml library (CVE-2024-45409, CVSS score: 10.0), which could allow an attacker to log in as an arbitrary user within the vulnerable system. It was addressed by the maintainers last week. The

## Background Multiple caveats over the same indirect subject type on the same relation can result in no permission being returned when permission is expected For example, given this schema: ``` definition user {} caveat somecaveat(somefield int) { somefield == 42 } definition group { relation member: user } definition resource { relation viewer: group#member with somecaveat permission view = folder->view } ``` If the resource has multiple groups, and each group is caveated, it is possible for the returned permission to be "no permission" when permission is expected. ## Impact Permission is returned as NO_PERMISSION when PERMISSION is expected on the CheckPermission API. ## Workarounds Do not use caveats or do not use caveats on an indirect subject type with multiple entries

Ubuntu Security Notice 7019-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 7000-2 - USN-7000-1 fixed vulnerabilities in Expat. This update provides the corresponding updates for Ubuntu 22.04 LTS. Shang-Hung Wan discovered that Expat did not properly handle certain function calls when a negative input length was provided. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code.

### Impact It's possible for any user knowing the ID of a notification filter preference of another user, to enable/disable it or even delete it. The impact is that the target user might start loosing notifications on some pages because of this. This vulnerability is present in XWiki since 13.2-rc-1. ### Patches The vulnerability has been patched in XWiki 14.10.21, 15.5.5, 15.10.1, 16.0-rc-1. The patch consists in checking properly the rights of the user before performing any action on the filters. ### Workarounds It's possible to fix manually the vulnerability by editing the document `XWiki.Notifications.Code.NotificationPreferenceService` to apply the changes performed in this commit e8acc9d8e6af7dfbfe70716ded431642ae4a6dd4. ### References * JIRA ticket: https://jira.xwiki.org/browse/XWIKI-20337 * Commit: e8acc9d8e6af7dfbfe70716ded431642ae4a6dd4 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https...

Broadcom on Tuesday released updates to address a critical security flaw impacting VMware vCenter Server that could pave the way for remote code execution. The vulnerability, tracked as CVE-2024-38812 (CVSS score: 9.8), has been described as a heap-overflow vulnerability in the DCE/RPC protocol. "A malicious actor with network access to vCenter Server may trigger this vulnerability by sending a
