New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
SynopsisThe remote host is susceptible to directory traversal with write capability by a remote, unauthenticated attacker.
DescriptionThe remote Citrix SD-WAN Center or NetScaler SD-WAN Center is susceptible to directory traversal and file writes in arbitrary locations. This is due to improper sanitization of user-supplied input in the applianceSettingsFileTransfer action of ApplianceSettingsController. An unauthenticated, remote attacker can exploit this by routing traffic through the Collector controller and supplying crafted values for 'filename', 'filedata', and 'workspace_id'. This allows writing files to locations writable by the 'www-data' user, as well as writing crafted PHP files to /home/talariuser/www/app/webroot/files/ to execute arbitrary PHP code.
SolutionUpgrade to Citrix SD-WAN Center version 10.2.3 or later or NetScaler SD-WAN Center version 10.0.8 or later.
