Insufficient input validation in NetScaler ADC and NetScaler Gateway when configured as a SAML IDP leading to memory overread

Citrix NetScaler ADC and NetScaler Gateway contain a memory overflow vulnerability that could allow for remote code execution and/or denial of service.

Citrix Session Recording contains an improper privilege management vulnerability that could allow for privilege escalation to NetworkService Account access. An attacker must be an authenticated user in the same Windows Active Directory domain as the session recording server domain.

Citrix Session Recording contains a deserialization of untrusted data vulnerability that allows limited remote code execution with privilege of a NetworkService Account access. Attacker must be an authenticated user on the same intranet as the session recording server.

Citrix NetScaler ADC and Gateway contain an out-of-bounds read vulnerability due to insufficient input validation. This vulnerability can lead to memory overread when the NetScaler is configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) OR AAA virtual server. Known ransomware use: Known.

Citrix NetScaler ADC and Gateway contain a buffer overflow vulnerability leading to unintended control flow and Denial of Service. NetScaler must be configured as Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) OR AAA virtual server.

Citrix NetScaler ADC and NetScaler Gateway contain a buffer overflow vulnerability that allows for a denial-of-service when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server.

Citrix NetScaler ADC and NetScaler Gateway contain a code injection vulnerability that allows for authenticated remote code execution on the management interface with access to NSIP, CLIP, or SNIP.

Citrix NetScaler ADC and NetScaler Gateway contain a buffer overflow vulnerability that allows for sensitive information disclosure when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server. Known ransomware use: Known.

Citrix Content Collaboration contains an improper access control vulnerability that could allow an unauthenticated attacker to remotely compromise customer-managed ShareFile storage zones controllers.

Citrix NetScaler ADC and NetScaler Gateway contains a code injection vulnerability that allows for unauthenticated remote code execution. Known ransomware use: Known.

Citrix Application Delivery Controller (ADC) and Gateway, when configured with SAML SP or IdP configuration, contain an authentication bypass vulnerability that allows an attacker to execute code as administrator.

Citrix SD-WAN and NetScaler SD-WAN allow SQL Injection.

Authenticated Command Injection in Citrix SD-WAN Appliance and NetScaler SD-WAN Appliance.

Improper Access Control in Citrix ShareFile storage zones controller may allow an unauthenticated attacker to remotely compromise the storage zones controller. Known ransomware use: Known.

Citrix ADC, Citrix Gateway, and multiple Citrix SD-WAN WANOP appliance models contain an unspecified vulnerability that could allow an unauthenticated attacker to perform code execution. Known ransomware use: Known.

Citrix ADC, Citrix Gateway, and multiple Citrix SD-WAN WANOP appliance models contain an authorization bypass vulnerability that may allow unauthenticated access to certain URL endpoints. The attacker must have access to the NetScaler IP (NSIP) in order to perform exploitation.

Citrix ADC, Citrix Gateway, and multiple Citrix SD-WAN WANOP appliance models contain an information disclosure vulnerability.

Citrix StoreFront Server contains an XML External Entity (XXE) processing vulnerability that may allow an unauthenticated attacker to retrieve potentially sensitive information. Known ransomware use: Known.

Citrix ADC, Citrix Gateway, and multiple Citrix SD-WAN WANOP appliance models contain an information disclosure vulnerability.
