Memory overflow vulnerability leading to unpredictable or erroneous behavior and Denial of Service

Memory overflow vulnerability NetScaler ADC and NetScaler Gateway leading to unpredictable or erroneous behavior and Denial of Service if the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server

Arbitrary File Read (Unauthenticated)

Insufficient input validation leading to memory overread

Insufficient input validation in NetScaler ADC and NetScaler Gateway leading to memory overread if NetScaler ADC or NetScaler Gateway is configured as a SAML IDP

Insufficient input validation leading to memory overread

Insufficient input validation leading to memory overread in NetScaler ADC and NetScaler Gateway if the TCP TimeStamp is enabled in TCP Profile and is associated with the virtual server (of type LB, CS, VPN) or the service configured on NetScaler

Multiple Memory overflow vulnerabilities leading to unpredictable or erroneous behavior and Denial of Service

Multiple Memory overflow vulnerabilities in NetScaler ADC and NetScaler Gateway leading to unpredictable or erroneous behavior and Denial of Service if NetScaler ADC is configured as an LB of type Oracle OR NetScaler ADC is configured as a DNS Proxy OR NetScaler ADC is configured as a DNS recursive resolver deployment

Denial of service via malformed HTTP/2 requests

Denial of service via malformed HTTP/2 requests in NetScaler ADC and NetScaler Gateway if HTTP/2 is enabled in HTTP Profile and associated with the virtual server (of type LB, CS, VPN) or the service configured on NetScaler

The web management interface in Citrix NetScaler 8.0 build 47.8 stores the device's primary IP address in a cookie, which might allow remote attackers to obtain sensitive network configuration information if this address is not the same as the address being used by the web interface.

The web management interface in Citrix NetScaler 8.0 build 47.8 uses weak encryption (XOR of unpadded data) to store credentials within a cookie, which makes it easier for remote attackers to obtain cleartext credentials when a cookie is captured via a known-plaintext attack.

Cross-site scripting (XSS) vulnerability in ws/generic_api_call.pl in Citrix NetScaler 8.0 build 47.8 allows remote attackers to inject arbitrary web script or HTML via the standalone parameter and other unspecified parameters.

The default configuration of the Security global settings on the Citrix NetScaler Access Gateway appliance with Enterprise Edition firmware 9.0, 8.1, and earlier specifies Allow for the Default Authorization Action option, which might allow remote authenticated users to bypass intended access restrictions.

bash: specially-crafted environment variables can be used to inject shell commands

GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.

bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

Insufficient input validation leading to memory overread

Insufficient input validation in NetScaler ADC and NetScaler Gateway when configured as a SAML IDP leading to memory overread

Citrix NetScaler SD-WAN devices through v9.1.2.26.561201 allow remote attackers to execute arbitrary shell commands as root via a CGISESSID cookie. On CloudBridge (the former name of NetScaler SD-WAN) devices, the cookie name was CAKEPHP rather than CGISESSID.

Authenticated privilege escalation

Authenticated privilege escalation in NetScaler Console and NetScaler Agent allows.
