Arch Linux Security Advisory ASA-201609-21 ========================================== Severity: Medium Date : 2016-09-22 CVE-ID : CVE-2016-5388 Package : tomcat7 Type : proxy injection Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package tomcat7 before version 7.0.72-1 is vulnerable to proxy injection. Resolution ========== Upgrade to 7.0.72-1. # pacman -Syu "tomcat7>=7.0.72-1" The problems have been fixed upstream in version 7.0.72. Workaround ========== None. Description =========== It was discovered that tomcat used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request. Impact ====== A remote attacker is able to use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request.
