Improper Authentication in Progress WS_FTP Server

Improper authentication in Progress Software WS_FTP Server versions prior to 2024.0.6 and 2025.0.3 on Windows could allow an unauthenticated remote attacker to access sensitive information, including administrative credentials.

Buffer overflow in Ipswitch WS_FTP Server with SSH 6.1.0.0 allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a long opendir command.

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.

IPswitch WS_FTP allows local users to gain additional privileges and modify or add mail accounts by setting the "flags" registry key to 1920.

Buffer overflows in WS_FTP 2.02 allow remote attackers to execute arbitrary code via long arguments to (1) DELE, (2) MDTM, (3) MLST, (4) MKD, (5) RMD, (6) RNFR, (7) RNTO, (8) SIZE, (9) STAT, (10) XMKD, or (11) XRMD.

Buffer overflow in WS_FTP FTP Server 3.1.1 allows remote authenticated users to execute arbitrary code via a long SITE CPWD command.

Multiple buffer overflows in WS_FTP 3 and 4 allow remote authenticated users to cause a denial of service and possibly execute arbitrary code via long (1) APPE (append) or (2) STAT (status) arguments.

WS_FTP 5.0.2 allows remote authenticated users to cause a denial of service (CPU consumption) via a CD command that contains an invalid path with a "../" sequence.

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.

Multiple buffer overflows in Ipswitch WS_FTP Server 4.0.2 (1) allow remote authenticated users to execute arbitrary code by causing a large error string to be generated by the ALLO handler, or (2) may allow remote FTP administrators to execute arbitrary code by causing a long hostname or username to be inserted into a reply to a STAT command while a file is being transferred.

Ipswitch WS_FTP Server 4.0.2 has a backdoor XXSESS_MGRYY username with a default password, which allows remote attackers to gain access.

Ipswitch WS_FTP Server 4.0.2 allows remote authenticated users to execute arbitrary programs as SYSTEM by using the SITE command to modify certain iFtpSvc options that are handled by iftpmgr.exe.

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.

Multiple buffer overflows in WS_FTP Server 5.05 before Hotfix 1, and possibly other versions down to 5.0, have unknown impact and remote authenticated attack vectors via the (1) XCRC, (2) XMD5, and (3) XSHA1 commands. NOTE: in the early publication of this identifier on 20060926, the description was used for the wrong issue.

IPswitch IMail allows local users to gain additional privileges and modify or add mail accounts by setting the "flags" registry key to 1920.

WS_FTP Server Ad Hoc Transfer Module .NET Deserialization Vulnerability

In WS_FTP Server versions prior to 8.7.4 and 8.8.2, a pre-authenticated attacker could leverage a .NET deserialization vulnerability in the Ad Hoc Transfer module to execute remote commands on the underlying WS_FTP Server operating system.

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.

WS_FTP Server Reflected Cross-Site Scripting in Administrative Interface

In WS_FTP Server versions before 8.8.5, reflected cross-site scripting issues have been identified on various user supplied inputs on the WS_FTP Server administrative interface.

Reflected XSS (via AngularJS sandbox escape expressions) exists in Progress Ipswitch WS_FTP Server 8.6.0. This can lead to execution of malicious code and commands on the client due to improper handling of user-provided input. By inputting malicious payloads in the subdirectory searchbar or Add folder filename boxes, it is possible to execute client-side commands. For example, there is Client-Side Template Injection via subFolderPath to the ThinClient/WtmApiService.asmx/GetFileSubTree URI.

WS_FTP Server Arbitrary File Upload

In WS_FTP Server versions prior to 8.7.6 and 8.8.4, an unrestricted file upload flaw has been identified. An authenticated Ad Hoc Transfer user has the ability to craft an API call which allows them to upload a file to a specified location on the underlying operating system hosting the WS_FTP Server application.
