CVE-2023-41333

Cilium is vulnerable: an attacker who can create/modify CiliumNetworkPolicy objects in a namespace can bypass namespace restrictions and affect traffic across the entire cluster by crafting an endpointSelector that uses the DoesNotExist operator on the reserved:init label. The issue requires API ...

CVE-2023-39347 Cilium NetworkPolicy bypass via pod labels

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to update pod labels can cause Cilium to apply incorrect network policies. This issue arises due to the fact that on pod update, Cilium incorrectly uses user-provided pod labels...

GHSA-WG6P-JMPC-XJMR Backstage Scaffolder plugin has insecure sandbox

The Backstage scaffolder-backend plugin uses a templating library that requires a sandbox, as it by design allows for code injection. The library used for this sandbox so far has been vm2, but in light of several past vulnerabilities and existing vulnerabilities that may not have a fix, the plugi...

KeePass vulnerability allows attackers to access the master password

KeePass is a free open source password manager, which helps you to manage your passwords and stores them in encrypted form. In fact, KeePass encrypts the whole database, i.e. not only your passwords, but also your user names, URLs, notes, etc. That encrypted database can only be opened with the...

Bypassing a Theft Threat Model

Thieves cut through the wall of a coffee shop to get to an Apple store, bypassing the alarms in the process. I wrote about this kind of thing in 2000, in Secrets and Lies page 318: My favorite example is a band of California art thieves that would break into peoples houses by cutting a hole in...

Intel CPU vulnerabilities fixed. But should you update?

Microsoft has released out of band updates for information disclosure vulnerabilities in Intel CPUs. The normal gut reaction would be to install out of band updates as soon as possible. Microsoft wouldnt be releasing the updates ahead of the regular cycle without good reason, would it? Well, mayb...

Nextcloud: [user_oidc] Unencrypted Communications

The OpenID Connect User Backend allows users to login to Nextcloud using SSO and is - according to the policy - part of the main scope of this program. The implementation supports plain HTTP without TLS and transfers sensitive information such as OIDC clientsecrets in an unencrypted manner...

Hertzbleed exposes computers’ secret whispers

Hertzbleed is the name for a vulnerability that can be used to obtain cryptographic keys and other secret data from Intel and AMD CPUs, remotely. It works by monitoring changes in power consumption, which can be deduced by the careful timing of known workloads, thanks to a processor power saving...

Hcltm - Documenting Your Threat Models With HCL

Threat Modeling with HCL Overview There are many different ways in which a threat model can be documented. From a simple text file, to more in-depth word documents, to fully instrumented threat models in a centralised solution. Two of the most valuable attributes of a threat model are being able ...

This New Tool Can Retrieve Pixelated Text from Redacted Documents

The practice of blurring out text using a method called pixelation may not be as secure as previously thought. While the most foolproof way of concealing sensitive textual information is to use opaque black bars, other redaction methods like pixelation can achieve the opposite effect, enabling th...

Improper Verification of Cryptographic Signature in fastecdsa

An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s-1, the signature verification fails even if the signature is correct. This behavior is not solely a...

Relax. Internet password books are OK

Passwords are a hot topic on social media at the moment, due to the re-emergence of a discussion about good password management practices. There’s a wealth of password management options available, some more desirable than others. The primary recommendation online is usually a software-based...
