Citrix · Citrix Netscaler · CVE-2015-2841
**Name of the Vulnerable Software and Affected Versions**
Citrix NetScaler versions 10.5
**Description**
The issue allows remote attackers to bypass intended firewall restrictions by using a crafted Content-Type header. This can be achieved with specific Content-Types, such as `application/octet-stream` and `text/xml`.
**Recommendations**
For version 10.5, consider restricting or validating the Content-Type header to prevent bypassing of firewall restrictions. As a temporary workaround, restrict access to sensitive areas of the application protected by the NetScaler AppFirewall until a more permanent solution is available.
