Reflected code injection 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 allows the modification of a file download.

Reflected code injection 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 allows the modification of a file download.

Please refer to advisory CTX276688 for more information.

The remote Citrix SD-WAN WANOP device is version 10.2.x prior to 10.2.7, 11.0.x prior to 11.0.3d, 11.1.x prior to 11.1.1a. It is, therefore, affected by multiple vulnerabilities:

  - An authorization bypass vulnerability exists in Citrix SD-WAN WANOP devices. An unauthenticated, remote     attacker with access to the NSIP/management interface can exploit this issue to bypass authorization.     (CVE-2020-8193)

  - A code injection vulnerability exists in Citrix SD-WAN WANOP devices. An unauthenticated, remote attacker     with access to the NSIP/management interface can exploit this issue to create a malicious file which, if     executed by a victim on the management network, could allow the attacker arbitrary code execution in the     context of that user. (CVE-2020-8194)

  - A cross-site scripting vulnerability exists in Citrix SD-WAN WANOP devices. An unauthenticated, remote     attacker can exploit this issue by convincing a user to click a specially crafted URL, to execute     arbitrary script code in a user's browser session. (CVE-2020-8191, CVE-2020-8198)

In addition, Citrix SD-WAN WANOP devices are also affected by several additional vulnerabilities including configuration-dependent privilege escalations, information disclosures, and a denial of service (DoS) vulnerability.
Please refer to advisory CTX276688 for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Citrix ADC or Citrix NetScaler Gateway device is version 10.5.x prior to 10.5-70.18, 11.1.x prior to 11.1-64.14, 12.0.x prior to 12.0-63.21, 12.1.x prior to 12.1-57.18, 12.1-FIPS prior to 12.1-55.179 or 13.0.x prior to 13.0-58.30.
It is, therefore, affected by multiple vulnerabilities:

  - An authorization bypass vulnerability exists in Citrix ADC and NetScaler Gateway devices. An     unauthenticated remote attacker with access to the NSIP/management interface can exploit this to bypass     authorization. (CVE-2020-8193)

  - A code injection vulnerability exists in Citrix ADC and NetScaler Gateway devices. An unauthenticated     remote attacker with access to the NSIP/management interface can exploit this to create a malicious file     which, if executed by a victim on the management network, could allow the attacker arbitrary code execution     in the context of that user.
