Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway 10.5 before build 67.13, 11.0 before build 71.22, 11.1 before build 56.19, and 12.0 before build 53.22 might allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT attack.

A vulnerability has been identified in the management interface of Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway 10.1 before build 135.18, 10.5 before build 66.9, 10.5e before build 60.7010.e, 11.0 before build 70.16, 11.1 before build 55.13, and 12.0 before build 53.13 (except for build 41.24) that, if exploited, could allow an attacker with access to the NetScaler management interface to gain administrative access to the appliance.

A heap overflow vulnerability in Citrix NetScaler Gateway versions 10.1 before 135.8/135.12, 10.5 before 65.11, 11.0 before 70.12, and 11.1 before 52.13 allows a remote authenticated attacker to run arbitrary commands via unspecified vectors.

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.

Cross-site scripting (XSS) vulnerability in vpn/js/gateway_login_form_view.js in Citrix NetScaler Gateway 11.0 before Build 66.11 allows remote attackers to inject arbitrary web script or HTML via the NSC_TMAC cookie.

Multiple cross-site scripting (XSS) vulnerabilities in the Nitro API in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway before 10.1 Build 133.9, 10.5 before Build 58.11, and 10.5.e before Build 56.1505.e on NetScaler Service Delivery Appliance Service VM (SVM) devices allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The administration UI in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway before 10.1 Build 133.9, 10.5 before Build 58.11, and 10.5.e before Build 56.1505.e on NetScaler Service Delivery Appliance Service VM (SVM) devices allows attackers to obtain sensitive information via unspecified vectors.

The Nitro API in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway before 10.1 Build 133.9, 10.5 before Build 58.11, and 10.5.e before Build 56.1505.e on NetScaler Service Delivery Appliance Service VM (SVM) devices allow attackers to obtain credentials via the browser cache.

Multiple unspecified vulnerabilities in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway before 10.1 Build 132.8, 10.5 before Build 57.7, and 10.5e before Build 56.1505.e allow remote attackers to gain privileges via unknown vectors, related to the (1) Command Line Interface (CLI) and the (2) Web User Interface (UI).
