Cloud Credentials: New Attack Surface for Old Problem

SAN FRANCISCO – Credential theft and abuse have long been a nagging problem for local network administrators. The threat surface ranges from pretexting scams to insiders who abuse network privileges in order to grant themselves higher permissions than otherwise assigned. Here at RSA Conference,...

kernel: drm/vmwgfx: fix integer overflow in vmw_surface_define_ioctl()

An out-of-bounds write vulnerability was found in the Linux kernel's vmwsurfacedefineioctl function, in the 'drivers/gpu/drm/vmwgfx/vmwgfxsurface.c' file. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely...

Zero Trust and the Slowly Boiled Frog

Disclaimer: No actual frogs were harmed in the writing of the blog post. We wouldn't do that. We like frogs. What is Zero Trust Networking? The Zero Trust security model was proposed by John Kindervag of Forrester Research back in 2010. The concept is that the traditional trust model of "trust, b...

EulerOS 2.0 SP1 : libxml2 (EulerOS-SA-2018-1070)

According to the versions of the libxml2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Google Chrome prior to 62.0.3202.62 and other products, allowed a remote...

How to mitigate rapid cyberattacks such as Petya and WannaCrypt

In the first blog post of this 3-part series, we introduced what rapid cyberattacks are and illustrated how rapid cyberattacks are different in terms of execution and outcome. In the second blog post, we provided some details on Petya and how it worked. In this final blog post, we will share:...

Design/Logic Flaw

A flaw in libxml2 allows remote XML entity inclusion with default parser flags i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes. Depending on the context, this may expose a higher-risk attack surface in libxml2 not...

Meltdown and Spectre Aren’t Business as Usual

The new year brought a new vulnerability type — the CPU-based Meltdown and Spectre bugs — that’s forcing vendors and IT departments to modify long-standing ways of identifying threats, prioritizing remediation, managing patches and evaluating risk. “Meltdown and Spectre are different...

Data Masking 101 – Whiteboard Wednesday [Video]

Data masking is an effective way to protect a large majority of your organization’s data. It replaces original data with realistic, but fictional data—reducing production data sprawl and your attack surface footprint, while maintaining the data's use for things like development, analytics modelin...

CVE-2017-14953

HikVision Wi-Fi IP cameras, when used in a wired configuration, allow physically proximate attackers to trigger association with an arbitrary access point by leveraging a default SSID with no WiFi encryption or authentication. NOTE: Vendor states that this is not a vulnerability, but more an...

CVE-2017-14953

CVE-2017-14953 affects Hikvision Wi‑Fi IP cameras (example: DS-2CD2432F-IW) used in wired configurations. The vulnerability arises from a default unencrypted, unauthenticated SSID (e.g., “davinci”) enabling physically proximate attackers to force association with an arbitrary access point, potent...
