Nginx < 1.4.1 ngx_http_proxy_module.c Multiple Vulnerabilities

According to its Server response header, the installed version of nginx is greater than or equal to 1.1.4 and prior to 1.2.9, or greater than or equal to 1.3.0 and prior to 1.4.1. It is, therefore, affected by multiple vulnerabilities :

• A stack-based buffer overflow in ‘ngx_http_parse.c’ may allow a remote attacker to execute arbitrary code or trigger a denial of service condition via a specially crafted HTTP request. This vulnerability only affects versions greater than or equal to 1.3.9 and less than 1.4.1. (CVE-2013-2028)

• A memory disclosure vulnerability in ‘ngx_http_parse.c’ affects servers that use ‘proxy_pass’ to untrusted upstream servers. This issue can be triggered by a remote attacker via a specially crafted HTTP request. Failed attempts may result in a denial of service condition. (CVE-2013-2070)

Note that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
