Citrix Netscaler Gateway

Citrix ADC and Citrix/NetScaler Gateway before 13.0-82.41, 12.1-62.23, 11.1-65.20 and Citrix ADC 12.1-FIPS before 12.1-55.238 suffer from improper access control allowing SAML authentication hijack through a phishing attack to steal a valid user session. Note that Citrix ADC or Citrix Gateway must be configured as a SAML SP or a SAML IdP for this to be possible.

Citrix ADC and Citrix/NetScaler Gateway 13.0 before 13.0-76.29, 12.1-61.18, 11.1-65.20, Citrix ADC 12.1-FIPS before 12.1-55.238, and Citrix SD-WAN WANOP Edition before 11.4.0, 11.3.2, 11.3.1a, 11.2.3a, 11.1.2c, 10.2.9a suffers from uncontrolled resource consumption by way of a network-based denial-of-service from within the same Layer 2 network segment. Note that the attacker must be in the same Layer 2 network segment as the vulnerable appliance.

Improper input validation in Citrix ADC and Citrix Gateway versions before 13.0-58.30, 12.1-57.18, 12.0-63.21, 11.1-64.14 and 10.5-70.18 and Citrix SDWAN WAN-OP versions before 11.1.1a, 11.0.3d and 10.2.7 allows reflected Cross Site Scripting (XSS).

The Administrative Web Interface in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway 11.x before 11.0 Build 64.34, 10.5 before 10.5 Build 59.13, 10.5.e before Build 59.1305.e, and 10.1 allows remote attackers to conduct clickjacking attacks via unspecified vectors.

Improper input validation in Citrix ADC and Citrix Gateway versions before 13.0-58.30, 12.1-57.18, 12.0-63.21, 11.1-64.14 and 10.5-70.18 and Citrix SDWAN WAN-OP versions before 11.1.1a, 11.0.3d and 10.2.7 resulting in Stored Cross-Site Scripting (XSS).

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.

Open redirect vulnerability allows a remote unauthenticated attacker to redirect users to arbitrary websites

Citrix NetScaler Gateway 12.1 before build 50.31, 12.0 before build 60.9, 11.1 before build 60.14, 11.0 before build 72.17, and 10.5 before build 69.5 and Application Delivery Controller (ADC) 12.1 before build 50.31, 12.0 before build 60.9, 11.1 before build 60.14, 11.0 before build 72.17, and 10.5 before build 69.5 allow remote attackers to obtain sensitive plaintext information because of a TLS Padding Oracle Vulnerability when CBC-based cipher suites are enabled.

The TLS and DTLS processing functionality in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway devices with firmware 9.x before 9.3 Build 68.5, 10.0 through Build 78.6, 10.1 before Build 130.13, 10.1.e before Build 130.1302.e, 10.5 before Build 55.8, and 10.5.e before Build 55.8007.e makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a variant of CVE-2014-3566 (aka POODLE).
