This advisory details a missing authentication and access control vulnerability allowing an unauthenticated attacker to gain unauthorised access to image data uploaded to CodiMD. Due to the insecure random filename generation functionality in the underlying Formidable library, filenames for uploaded images could be determined and the likelihood of this issue being exploited was increased.
Slack integrations such as webhook APIs are often used to alert on user actions to internal teams. A vulnerability was noted when user supplied data containing a large amount of white space was included in a request to the Slack webhook API. By including enough white space in this data, the messages would be split and truncated. As a result, the malicious payload after the whitespace would appear as a standalone message from the Slack bot. An attacker could exploit this to forge messages containing Slack message markup to perform social engineering and other attacks if an integration, such as a website or other software, included unvalidated user input in the message to the Slack webhook.
Configuring USBGuard without explicitly specifying vendor and product IDs allows an attacker to bypass some USB authorisation policies on Linux. A device may claim to belong to one USB class (e.g. say it’s a keyboard), but actually act as a network adapter, mass storage or other more exotic device. The Gnome desktop’s USB protection policies are vulnerable by default.
TLS is good, arguably necessary, but managing PKI makes me feel bad. Is there no other way? This article will show how you can reap the benefits of mutual TLS quickly and easily without the mire of PKI.
This article discusses Airtable Formula injection, a vulnerability that occurs when untrusted input is included in an Airtable formula. We’ll cover the vulnerability fundamentals, detection, exploitation and some thoughts on remediation.
2024 was a year. What better way to close it off than by releasing some silly, but ultimately useful, tools. This article discusses and releases 4 USB HID fuzzing tools that get far, far, too much use. Meet the four horsemen of the HID apocalypse. Plug them in and watch the chaos.
