Server-Side Request Forgery (SSRF) in Citrix SD-WAN Standard/Premium Editions on or after 11.4.0 and before 11.4.4.46 allows an attacker to disclose limited information from the appliance via Access to management IP.

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.

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.

Privilege Escalation to root administrator (nsroot)

Reflected Cross-Site Scripting (XSS)

Unauthenticated remote code execution

A vulnerability has been discovered in the Citrix Secure Access client for Ubuntu which, if exploited, could allow an attacker to remotely execute code if a victim user opens an attacker-crafted link and accepts further prompts.

A vulnerability has been discovered in the Citrix Secure Access client for Windows which, if exploited, could allow an attacker with access to an endpoint with Standard User Account that has the vulnerable client installed to escalate their local privileges to that of NT AUTHORITY\SYSTEM.

A vulnerability has been discovered in the customer-managed ShareFile storage zones controller which, if exploited, could allow an unauthenticated attacker to remotely compromise the customer-managed ShareFile storage zones controller.

Users with only access to launch VDA applications can launch an unauthorized desktop

Arbitrary file read in Citrix ADC and Citrix Gateway 

Cross site scripting vulnerability in Citrix ADC and Citrix Gateway  in allows and attacker to perform cross site scripting

A vulnerability has been identified in Citrix Workspace app for Linux that, if exploited, may result in a malicious local user being able to gain access to the Citrix Virtual Apps and Desktops session of another user who is using the same computer from which the ICA session is launched.

Vulnerabilities have been identified that, collectively, allow a standard Windows user to perform operations as SYSTEM on the computer running Citrix Workspace app.

A vulnerability has been identified that, if exploited, could result in a local user elevating their privilege level to NT AUTHORITY\SYSTEM on a Citrix Virtual Apps and Desktops Windows VDA.

A malicious user can cause log files to be written to a directory that they do not have permission to write to.

Unauthenticated remote arbitrary code execution

User login brute force protection functionality bypass

Unauthorized access to Gateway user capabilities

Remote desktop takeover via phishing

Temporary disruption of the ADM license service. The impact of this includes preventing new licenses from being issued or renewed by Citrix ADM.

Corruption of the system by a remote, unauthenticated user. The impact of this can include the reset of the administrator password at the next device reboot, allowing an attacker with ssh access to connect with the default administrator credentials after the device has rebooted.

Cross-site Scripting (XSS) vulnerability in Citrix StoreFront affects version 1912 before CU5 and version 3.12 before CU9

Citrix Federated Authentication Service (FAS) 7.17 - 10.6 causes deployments that have been configured to store a registration authority certificate's private key in a Trusted Platform Module (TPM) to incorrectly store that key in the Microsoft Software Key Storage Provider (MSKSP). This issue only occurs if PowerShell was used when configuring FAS to store the registration authority certificate’s private key in the TPM. It does not occur if the TPM was not selected for use or if the FAS administration console was used for configuration.

Citrix XenApp 6.5, when 2FA is enabled, allows a remote unauthenticated attacker to ascertain whether a user exists on the server, because the 2FA error page only occurs after a valid username is entered. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
