ISSUES

 

CVE-2016-9099
Severity / CVSSv2 Low / 2.6 (AV:N/AC:H/Au:N/C:N/I:P/A:N)
References SecurityFocus: BID 102455 / NVD: CVE-2016-9099
Impact Open redirection
Description A remote attacker can use a crafted management console URL in a phishing attack to redirect the target user to a malicious web site.  Exploiting this vulnerability does not allow the attacker to bypass the security controls enforced by the ASG/ProxySG policy.  If ASG/ProxySG are configured to intercept traffic from the target user, they will enforce the configured security controls on the redirected request to the malicious web site.

 

CVE-2016-9100
Severity / CVSSv2 Medium / 5.1 (AV:N/AC:H/Au:N/C:P/I:P/A:P)
References SecurityFocus: BID 102454 / NVD: CVE-2016-9100
Impact Information disclosure
Description An attacker with access to the client host of an authenticated administrator user can, under certain circumstances, obtain sensitive authentication credential information.

 

CVE-2016-10256
Severity / CVSSv2 Medium / 5.0 (AV:N/AC:M/Au:N/C:P/I:P/A:N)
References SecurityFocus: BID 102451  / NVD: CVE-2016-10256
Impact Cross-site scripting (XSS)
Description A remote attacker can use a crafted management console URL in a phishing attack to inject arbitrary JavaScript code into the management console web client application. This is a separate vulnerability from CVE-2016-10257.

 

CVE-2016-10257
Severity / CVSSv2 Medium / 5.0 (AV:N/AC:M/Au:N/C:P/I:P/A:N)
