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.

Arbitrary file read in Citrix ADC and Citrix Gateway?

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.

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.

Cross SiteScripting vulnerability in Citrix Session Recording allows attacker to perform Cross Site Scripting

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

Privilege Escalation to root administrator (nsroot)

Reflected Cross-Site Scripting (XSS)

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.

Unauthenticated denial of service

An improper privilege vulnerability has been discovered in Citrix Gateway Plug-in for Windows (Citrix Secure Access for Windows) <21.9.1.2 what could allow an attacker who has gained local access to a computer with Citrix Gateway Plug-in installed, to corrupt or delete files as SYSTEM.

An Improper Access Control vulnerability exists in Citrix Workspace App for Linux 2012 - 2111 with App Protection installed that can allow an attacker to perform local privilege escalation.

In Citrix XenMobile Server through 10.12 RP9, there is an Authenticated Directory Traversal vulnerability, leading to remote code execution.

An uncontrolled resource consumption vulnerability exists in Citrix ADC <13.0-83.27, <12.1-63.22 and 11.1-65.23 that could allow an attacker with access to NSIP or SNIP with management interface access to cause a temporary disruption of the Management GUI, Nitro API, and RPC communication.

A unauthenticated denial of service vulnerability exists in Citrix ADC <13.0-83.27, <12.1-63.22 and 11.1-65.23 when configured as a VPN (Gateway) or AAA virtual server could allow an attacker to cause a temporary disruption of the Management GUI, Nitro API, and RPC communication.

An issue has been identified in the CTX269106 mitigation tool for Citrix ShareFile storage zones controller which causes the ShareFile file encryption option to become disabled if it had previously been enabled. Customers are only affected by this issue if they previously selected “Enable Encryption” in the ShareFile configuration page and did not re-select this setting after running the CTX269106 mitigation tool. ShareFile customers who have not run the CTX269106 mitigation tool or who re-selected “Enable Encryption” immediately after running the tool are unaffected by this issue.

A vulnerability has been identified in Citrix Virtual Apps and Desktops that could, if exploited, allow a user of a Windows VDA that has either Citrix Profile Management or Citrix Profile Management WMI Plugin installed to escalate their privilege level on that Windows VDA to SYSTEM.

A session fixation vulnerability exists in Citrix ADC and Citrix Gateway 13.0-82.45 when configured SAML service provider that could allow an attacker to hijack a 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.

Citrix Cloud Connector before 6.31.0.62192 suffers from insecure storage of sensitive information due to sensitive information being stored in the Citrix Cloud Connector installation log files. Such information could be used by an malicious actor to access a Citrix Cloud environment. This issue affects all versions of Citrix Cloud Connector that were installed by passing secure client parameters for installation via the command line. The issue does not affect Citrix Cloud Connector if it was installed using the interactive installer or where a parameter file was used with the command-line installer.

An improper access control vulnerability exists in Citrix Workspace App for Windows potentially allows privilege escalation in CR versions prior to 2105 and 1912 LTSR prior to CU4.

Citrix Workspace App before 1912 on Windows has Insecure Permissions which allows local users to gain privileges during the uninstallation of the application.

Citrix Workspace App before 1912 on Windows has Insecure Permissions and an Unquoted Path vulnerability which allows local users to gain privileges during the uninstallation of the application.
