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.

The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious c…

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.

Improper privilege management on services run by Citrix Gateway Plug-in for Windows, versions before and including 13.0-61.48 and 12.1-58.15, allows an attacker to modify arbitrary files.

Improper privilege management on services run by Citrix Gateway Plug-in for Windows, versions before and including 13.0-61.48 and 12.1-58.15, lead to privilege escalation attacks

Improper access control in Citrix ADC Gateway Linux client versions before 1.0.0.137 results in local privilege escalation to root.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

Integer overflow in the StartEpa method in the nsepacom ActiveX control (nsepa.exe) in Citrix Access Gateway Enterprise Edition Plug-in for Windows 9.x before 9.3-57.5 and 10.0 before 10.0-69.4 allows remote attackers to execute arbitrary code via a crafted Content-Length HTTP header, which triggers a heap-based buffer overflow.

Heap-based buffer overflow in the StartEpa method in the nsepacom ActiveX control (nsepa.exe) in Citrix Access Gateway Enterprise Edition Plug-in for Windows 9.x before 9.3-57.5 and 10.0 before 10.0-69.4 allows remote attackers to execute arbitrary code via a long CSEC HTTP response header.
