Summary
o Multiple vulnerabilities in the web-based GUI of Cisco AsyncOS Software for
Cisco Content Security Management Appliance (SMA) could allow an
unauthenticated, remote attacker to redirect a user to a malicious web
page.
The vulnerabilities are due to improper input validation of the parameters
of an HTTP request. An attacker could exploit these vulnerabilities by
intercepting an HTTP request and modifying it to redirect a user to a
specific malicious URL. A successful exploit could allow the attacker to
redirect a user to a malicious web page or to obtain sensitive
browser-based information.
This type of attack is commonly referred to as an open redirect attack and
is used in phishing attacks to get users to unknowingly visit malicious
sites.
Cisco has released software updates that address these vulnerabilities.
There are no workarounds that address these vulnerabilities.
