Computer Network Defence Alert State


Radar Page

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


A buffer overflow vulnerability has been identified in Schneider Electric’s VAMPSET software product.

More info


The katello-configure package provides the katello-configure script, which configures the Katello installation, and the katello-upgrade script, which handles upgrades between versions. It was discovered that the default configuration of Elasticsearch enabled dynamic scripting, allowing a remote attacker to execute arbitrary MVEL expressions and Java code via the source parameter passed to _search.

More info.


NSS contained a race condition when performing certificate validation. An attacker could use this issue to cause NSS to crash, resulting in a denial of service, or possibly execute arbitrary code.

More info.


VMware NSX and vCNS contain an input validation vulnerability. This issue may allow for critical information disclosure.

More info.


Some vulnerabilities with an unknown impact have been reported in SRWare Iron.

More info.


Multiple vulnerabilities have been reported in D-Link DIR-826L, which can be exploited by malicious people to conduct cross-site request forgery attacks, bypass certain security restrictions, and compromise a vulnerable device.

More info.




IBM has published about 40 new bulletins, mostly to do with updated third party software in a variety of products, including IBM SONAS, IBM Cognos, IBM WebSphere MQ, IBM FileNet Content Manager, InfoSphere, Sterling, Workplace XT, and IBM Storwize.  You'll need to peruse for yourself to see if any of the bulletins are of interest.

More info.


Ubuntu has updated the curl libraries to correct flaws in cookie handling that could allow potential data leakage or malicious cookies.

More info.

A remote attacker can send a specially crafted UDP SNMP packet to trigger an off-by-one memory error in snmpHandleUdp() and potentially execute arbitrary code on the target system.

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.


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.
