In WS_FTP Server versions prior to 8.7.4 and 8.8.2,
a reflected cross-site scripting (XSS) vulnerability exists in WS_FTP Server's Ad Hoc Transfer module. An attacker could leverage this vulnerability to target WS_FTP Server users with a specialized payload which results in the execution of malicious JavaScript within the context of the victims browser.
In Progress WS_FTP Server before 8.8, it is possible for a host administrator to elevate their privileges via the administrative interface due to insufficient authorization controls applied on user modification workflows.
A Directory Traversal issue was discovered in SSHServerAPI.dll in Progress ipswitch WS_FTP Server 2018 before 8.6.1. An attacker can supply a string using special patterns via the SCP protocol to disclose WS_FTP usernames as well as filenames.
Unspecified vulnerability in the log analyzer in WS_FTP Server 5.05 before Hotfix 1, and possibly other versions down to 5.0, prevents certain sensitive information from being displayed in the (1) Files and (2) Summary tabs. NOTE: in the early publication of this identifier on 20060926, the description was used for the wrong issue.
Multiple buffer overflows in Ipswitch WS_FTP Server 5.05 before Hotfix 1 allow remote authenticated users to execute arbitrary code via long (1) XCRC, (2) XSHA1, or (3) XMD5 commands.
Ipswitch WS_FTP Server 4.0.2 allows remote attackers to cause a denial of service (disk consumption) and bypass file size restrictions via a REST command with a large size argument, followed by a STOR of a smaller file.
