Alert Details

Computer Network Defence Alert State

 

secwiz blankback cro tp

The Computer Network Defence Alert State is designed to give a granular and more dynamic visualisation of the current security threat.  Increase in alert state will occur immediately upon detection of a new threat and drop again by one level each working day.  The rationale is that vulnerabilities often occur in clusters, therefore reducing the alert state again quickly, will increase your visibility of new threats to the same product.  It is important that the radar page is viewed at least daily in order to track these changes. Reductions in alert state occur at approximately 1900 GMT/UTC. Significant vulnerabilities may remain for longer. Vulnerabilities on this page are predominantly remotely executable, very few local server exploits will be shown.

 

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  

Current Alerts

AlertTitleIBM

There are multiple vulnerabilities in IBM® Runtime Environment Java™ Technology Edition, Versions 5 and 6 that are used by IBM Rational ClearCase.

More info.

 

An Apache Cordova vulnerability was disclosed May 26, 2015. Apache Cordova is used by IBM Worklight and IBM MobileFirst Platform Foundation. Android applications built with the Cordova framework might allow a remote attacker to cause arbitrary commands to be executed in the application.

AlertTitleSuSE

SuSE has published a kernel update with fixes for multiple security vulnerabilities.  They've also updated xorg-x11-libX11.

More info.

 

OpenSUSE updated the kernel too.

More info.

AlertTitleLenovo

Lenovo Service Engine (LSE) is a utility in the BIOS that sends non-personally identifiable system data to Lenovo servers. Lenovo, Microsoft and an independent researcher have discovered possible ways this program could be exploited by an attacker, including a buffer overflow attack and an attempted connection to a Lenovo test server.  They recommend disabling the utility in the BIOS.

More info here and here.

AlertTitleNetwork

Multiple models of Chiyu Technology fingerprint access control devices contain a cross-site scripting (XSS) vulnerability and an authentication bypass vulnerability.

(under Network because an unauthenticated remote attacker may be able to view or modify device configuration, or obtain user credentials.)

Alert Definitions

NORMAL This alert state represents the normal level of security with minimal activity relating to the product.  The next stage above this level is 2, however falling alerts will go through 1 when returning to normal.

LOW This alert state indicates that an alert has been recognised for this product within the last few days but it is now returning to normal.  Inclusion of this level is for viewers that don't monitor this alert system regularly.

INCREASED This alert state indicates a need to increase the security posture due to an emerging threat for which there is currently no exploit, or you are witnessing the reduction in alert state after being at level 3 for more than 1 working day.

HIGH This alert state indicates a significant threat to the product, where exploits exist or where the vulnerability is potentially devastating.

PATCHES This alert state indicates that patches are available for vulnerabilities that had previously resulted in a need for the alert state to increase and subsequently fall. The level of 2 or 3 indicates the urgency to patch.

EXPLOIT This alert state indicates that exploit code is available for vulnerabilities that had previously resulted in a need for the alert state to increase and subsequently fall. The level of 2 or 3 indicates the threat of the exploit.

AlertNumberZ3

ZERO This alert state indicates that a vulnerability has been announced without the opportunity for the vendor to patch it before the details are made known.  These can be especially dangerous if exploit code is available. The level of 2 or 3 indicates the threat of the vulnerability.
