Improper Restriction of Operations within the Bounds of a Memory Buffer in NetScaler ADC and NetScaler Gateway allows Unauthenticated Denial of Service

Improper Control of Generation of Code ('Code Injection') in NetScaler ADC and NetScaler Gateway allows an attacker with access to NSIP, CLIP or SNIP with management interface to perform Authenticated (low privileged) remote code execution on Management Interface.

Denial of Service in NetScaler ADC and NetScaler Gateway when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA Virtual Server

Sensitive information disclosure in NetScaler ADC and NetScaler Gateway when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA  virtual server. 

A vulnerability has been discovered in Citrix ADC (formerly known as NetScaler ADC) and Citrix Gateway (formerly known as NetScaler Gateway), and Citrix SD-WAN WANOP Edition models 4000-WO, 4100-WO, 5000-WO, and 5100-WO. These vulnerabilities, if exploited, could lead to a phishing attack through a SAML authentication hijack to steal a valid user session.

A vulnerability has been discovered in Citrix ADC (formerly known as NetScaler ADC) and Citrix Gateway (formerly known as NetScaler Gateway), and Citrix SD-WAN WANOP Edition models 4000-WO, 4100-WO, 5000-WO, and 5100-WO. These vulnerabilities, if exploited, could lead to the limited available disk space on the appliances being fully consumed.

Improper Input Validation on Citrix ADC and Citrix Gateway 13.0 before 13.0-64.35, Citrix ADC and NetScaler Gateway 12.1 before 12.1-58.15, Citrix ADC 12.1-FIPS before 12.1-55.187, Citrix ADC and NetScaler Gateway 12.0, Citrix ADC and NetScaler Gateway 11.1 before 11.1-65.12, Citrix SD-WAN WANOP 11.2 before 11.2.1a, Citrix SD-WAN WANOP 11.1 before 11.1.2a, Citrix SD-WAN WANOP 11.0 before 11.0.3f, Citrix SD-WAN WANOP 10.2 before 10.2.7b leads to an HTML Injection attack against the SSL VPN web portal.

Multiple cross-site scripting (XSS) vulnerabilities in Citrix NetScaler ADC 10.5, 11.0, 11.1, and 12.0, and NetScaler Gateway 10.5, 11.0, 11.1, and 12.0 allow remote attackers to inject arbitrary web script or HTML via the Citrix NetScaler interface.

Directory traversal vulnerability in NetScaler ADC 10.5, 11.0, 11.1, and 12.0, and NetScaler Gateway 10.5, 11.0, 11.1, and 12.0 allows remote attackers to traverse the directory on the target system via a crafted request.

NetScaler ADC 10.5, 11.0, 11.1, and 12.0, and NetScaler Gateway 10.5, 11.0, 11.1, and 12.0 allow remote attackers to gain privilege on a target system.

NetScaler ADC 10.5, 11.0, 11.1, and 12.0, and NetScaler Gateway 10.5, 11.0, 11.1, and 12.0 allow remote attackers to download arbitrary files on the target system.

Command injection vulnerability in Citrix NetScaler ADC and NetScaler Gateway 11.0 before build 70.16, 11.1 before build 55.13, and 12.0 before build 53.13; and the NetScaler Load Balancing instance distributed with NetScaler SD-WAN/CloudBridge 4000, 4100, 5000 and 5100 WAN Optimization Edition 9.3.0 allows remote attackers to execute a system command or read arbitrary files via an SSH login prompt.

Citrix NetScaler ADC and NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, and 11.1 before Build 51.21 randomly generates GCM nonces, which makes it marginally easier for remote attackers to obtain the GCM authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270.

Unauthorized redirect vulnerability in Citrix NetScaler ADC before 10.1 135.8, 10.5 61.11, 11.0 65.31/65.35F and 11.1 47.14 allows a remote attacker to steal session cookies of a legitimate AAA user via manipulation of Host header.
