Detailsinfo

A vulnerability classified as problematic has been found in ProFTPD 1.2.1 (File Transfer Software). Affected is the function glob of the component Wildcard Character Handler. The manipulation with an unknown input leads to a memory allocation vulnerability. CWE is classifying the issue as CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. This is going to have an impact on availability. CVE summarizes:

The glob functionality in ProFTPD 1.2.1, and possibly other versions allows remote attackers to cause a denial of service (CPU and memory consumption) via commands with large numbers of wildcard and other special characters, as demonstrated using an ls command with multiple (1) "*/..", (2) "*/.*", or (3) ".*./*?/" sequences in the argument.

The weakness was published 12/31/2001 (Website). The advisory is shared for download at distro.conectiva.com.br. This vulnerability is traded as CVE-2001-1501 since 06/21/2005. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

A public exploit has been developed in Shell File. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept.
