Detailsinfo

A vulnerability was found in FTPPad FTP Client up to 1.2.0. It has been declared as critical. This vulnerability affects an unknown function of the component LIST Command Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

FTPPad <= 1.2.0 contains a stack-based buffer overflow vulnerability in its FTP directory listing parser. When the client connects to an FTP server and receives a crafted response to a LIST command containing an excessively long directory and filename, the application fails to properly validate input length. This results in a buffer overflow that overwrites the saved Extended Instruction Pointer (EIP), allowing remote attackers to execute arbitrary code.

The weakness was disclosed with Corelan Team. The advisory is shared for download at raw.githubusercontent.com. This vulnerability was named CVE-2010-20108 since 08/20/2025. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/21/2025).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
