VAR-200412-1139
Vulnerability from variot - Updated: 2025-04-03 22:21Multiple 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. Multiple vulnerabilities have been identified in the WS_FTP Server and client applications. The issues include two remote buffer overflow vulnerabilities in the client, a denial of service vulnerability in the server and an access validation issue in the server leading to remote command execution with SYSTEM privileges. These issues are undergoing further analysis. This BID will be divided into separate issues as analysis is completed. Progress Software Ipswitch WS_FTP Server is a set of FTP server software developed by Progress Software Company in the United States. It provides functions such as file transfer control and transfer encryption. A buffer error vulnerability exists in Progress Software Ipswitch WS_FTP Server version 4.0.2

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
