ProxyNow has been reported to be prone to multiple overflow vulnerabilities that may allow an attacker to execute arbitrary code in order to gain unauthorized access to a vulnerable system. The vulnerabilities present themselves when an attacker sends a HTTP GET request containing an excessively long URI to the server on TCP port 3128. The URI must be prefixed with the string 'ftp://'.
|
|
|
|
ProxyNow versions 2.75 and prior have been reported to be prone to these issues.
