Alert Details

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

AlertTitleAvant

Some vulnerabilities have been reported in Avant Browser, where some have an unknown impact and others can be exploited to conduct cross-site scripting attacks, bypass certain security restrictions, and compromise a user's system.

More info.

AlertTitleIBM

IBM Notes and Domino on x86 Linux are incorrectly built requesting an executable stack. This can make it easier for attackers to exploit vulnerabilities in Notes, Domino, and any of the child processes that they may spawn.

More info.

 

IBM has acknowledged multiple vulnerabilities in IBM InfoSphere Streams, which can be exploited by malicious users to manipulate certain data and by malicious people to disclose potentially sensitive information, manipulate certain data, bypass certain security restrictions, cause a DoS (Denial of Service), and compromise a vulnerable system.

More info.

AlertTitleSymantec

Symantec's Messaging Gateway management console is susceptible to a reflected cross-site scripting (XSS) issue found in one of the administrative interface pages. Successful exploitation could result in potential session hijacking or unauthorized actions directed against the console with the privileges of the targeted user's browser. 

More info.

AlertTitleRedHat

RedHat has reported a  flaw openshift-origin-broker. A remote attacker able to submit a request to openshift-origin-broker could bypass of the authentication checks to gain access to any OpenShift user account on the system.

More info.

 

RedHat reported a flaw in the Linux kernel processing of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake.

More info.

AlertTitleCisco

A vulnerability in the Session Initiation Protocol (SIP) inspection engine code could allow an unauthenticated, remote attacker to cause a slow memory leak, which may cause instability on the affected system. 
 More info.

AlertTitleApple

Apple released patches for OS X, iOS and Apple TV. The OS X patches apply for versions of OS X back to Lion (10.7.5). Vulnerabilities fixed by these patches can lead to remote code execution by visiting malicious web sites.

More info. (Hopefully they'll update the link soon)

AlertTitleIBM

IBM has acknowledged a vulnerability in IBM Rational Policy Tester, which can be exploited by malicious people to conduct session fixation attacks.  A patch is planned for June.

More info.

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.
