Citrix : Security Vulnerabilities, CVEs, CVSS score >= 9

The Citrix ICA (Independent Computing Architecture) protocol uses weak encryption (XOR) for user authentication.

Unspecified vulnerability in Citrix Presentation Server Client for Windows before 10.0 allows remote web sites to execute arbitrary code via unspecified vectors, related to the implementation of ICA connectivity through proxy servers.

Multiple unspecified vulnerabilities in (1) Net6Helper.DLL (aka Net6Launcher Class) 4.5.2 and earlier, (2) npCtxCAO.dll (aka Citrix Endpoint Analysis Client) in a Firefox plugin directory, and (3) a second npCtxCAO.dll (aka CCAOControl Object) before 4.5.0.0 in Citrix Access Gateway Standard Edition before 4.5.5 and Advanced Edition before 4.5 HF1 have unknown impact and attack vectors, possibly related to buffer overflows. NOTE: vector 3 might overlap CVE-2007-3679.

Buffer overflow in the Independent Management Architecture (IMA) service in Citrix Presentation Server (MetaFrame Presentation Server) 4.5 and earlier, Access Essentials 2.0 and earlier, and Desktop Server 1.0 allows remote attackers to execute arbitrary code via an invalid size value in a packet to TCP port 2512 or 2513.

Unspecified vulnerability in Citrix Access Gateway Standard Edition 4.5.7 and earlier and Advanced Edition 4.5 HF2 and earlier allows attackers to bypass authentication and gain "access to network resources" via unspecified vectors.

Multiple unspecified vulnerabilities in Citrix Licensing 11.5 have unknown impact and attack vectors, related to "underlying components of the License Management Console."

Citrix Online Plug-in for Windows for XenApp & XenDesktop before 11.2, Citrix Online Plug-in for Mac for XenApp & XenDesktop before 11.0, Citrix ICA Client for Linux before 11.100, Citrix ICA Client for Solaris before 8.63, and Citrix Receiver for Windows Mobile before 11.5 allow remote attackers to execute arbitrary code via (1) a crafted HTML document, (2) a crafted .ICA file, or (3) a crafted type field in an ICA graphics packet, related to a "heap offset overflow" issue.

The IICAClient interface in the ICAClient library in the ICA Client ActiveX Object (aka ICO) component in Citrix Online Plug-in for Windows for XenApp & XenDesktop before 12.0.3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted HTML document that triggers the reading of a .ICA file.

The web authentication form in the NT4 authentication component in Citrix Access Gateway Enterprise Edition 9.2-49.8 and earlier, and the NTLM authentication component in Access Gateway Standard and Advanced Editions before Access Gateway 5.0, allows attackers to execute arbitrary commands via shell metacharacters in the password field.

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.

Stack-based buffer overflow in the NSEPA.NsepaCtrl.1 ActiveX control in nsepa.ocx in Citrix Access Gateway Enterprise Edition 8.1 before 8.1-67.7, 9.0 before 9.0-70.5, and 9.1 before 9.1-96.4 allows remote attackers to execute arbitrary code via crafted HTTP header data.

The NSEPA.NsepaCtrl.1 ActiveX control in nsepa.ocx in Citrix Access Gateway Enterprise Edition 8.1 before 8.1-67.7, 9.0 before 9.0-70.5, and 9.1 before 9.1-96.4 attempts to validate signed DLLs by checking the certificate subject, not the signature, which allows man-in-the-middle attackers to execute arbitrary code via HTTP header data referencing a DLL that was signed with a crafted certificate.

Citrix Cloud.com CloudStack, and Apache CloudStack pre-release, allows remote attackers to make arbitrary API calls by leveraging the system user account, as demonstrated by API calls to delete VMs.

Citrix XenApp Online Plug-in for Windows 12.1 and earlier, and Citrix Receiver for Windows 3.2 and earlier could allow remote attackers to execute arbitrary code by convincing a target to open a specially crafted file from an SMB or WebDAV fileserver.

The XML Service interface in Citrix XenApp 6.5 and 6.5 Feature Pack 1 allows remote attackers to execute arbitrary code via unspecified vectors.
