Insufficient protection of secrets in Citrix XenMobile Server 10.12 before RP3, Citrix XenMobile Server 10.11 before RP6, Citrix XenMobile Server 10.10 RP6 and Citrix XenMobile Server before 10.9 RP5 discloses credentials of a service account.

Improper access control 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 limited information disclosure to low privileged users.

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 limited information disclosure to low privileged users.

In certain Citrix products, information disclosure can be achieved by an authenticated VPN user when there is a configured SSL VPN endpoint. This affects Citrix ADC and Citrix Gateway 13.0-58.30 and later releases before the CTX276688 update.

An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because small IOMMU mappings are unsafely combined into larger ones.

Citrix ShareFile StorageZones Controller before 5.4.2 has Information Exposure Through an Error Message.

There is a Sensitive Data Leakage issue in Citrix XenMobile Server 10.7 before RP3.

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.

System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel.

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 allow remote attackers to obtain sensitive information from the backend client TLS handshake by leveraging use of TLS with Client Certificates and a Diffie-Hellman Ephemeral (DHE) key exchange.

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.

Citrix Provisioning Services before 7.12 allows attackers to obtain sensitive information from kernel memory via unspecified vectors.

Citrix Provisioning Services before 7.12 allows attackers to obtain sensitive kernel address information via unspecified vectors.

Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains 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.

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).

Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway (formerly Access Gateway Enterprise Edition) before 9.3-62.4 and 10.x before 10.1-126.12 allows attackers to obtain sensitive information via vectors related to a cookie.

The Citrix GoToMeeting application 5.0.799.1238 for Android logs HTTP requests containing sensitive information, which allows attackers to obtain user IDs, meeting details, and authentication tokens via an application that reads the system log file.

Citrix Presentation Server Client for Windows before 10.200 does not clear "credential information" from process memory in unspecified circumstances, which might allow local users to gain privileges.

The installation process for Citrix Presentation Server 4.5 and Desktop Server 1.0, when MSI logging is enabled, stores database credentials in MSI log files, which allows local users to obtain these credentials by reading the log files.

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 portal interface in Citrix Access Gateway (aka Citrix Advanced Access Control) before Advanced Edition 4.5 HF1 places a session ID in the URL, which allows context-dependent attackers to hijack sessions by reading "residual information", including the a referer log, browser history, or browser cache.
