CyberRota Analysis
AI-GeneratedThe mod_sftp module in ProFTPD versions prior to 1.3.9c and 1.3.10rc3 is vulnerable to a heap-based buffer overflow, allowing authenticated low-privilege attackers to execute arbitrary code by sending specially crafted SFTP packet fragments that exceed the 16 KB reassembly buffer. This vulnerability can lead to significant security breaches, including the potential for attackers to redirect system calls and manipulate filesystem operations. Organizations using affected versions of ProFTPD should prioritize patching this vulnerability to mitigate the risk of exploitation.

Original NVD Description
ProFTPD before 1.3.9c and 1.3.10rc3 contains a heap-based buffer overflow vulnerability in the mod_sftp module that allows authenticated low-privilege attackers to achieve arbitrary code execution by sending crafted SFTP packet fragments exceeding the 16 KB reassembly buffer in the fxp.c component. Attackers can supply oversized fragments to trigger an incorrectly conditioned reallocation, corrupt pool freelist metadata, overwrite the root_fs BSS global pointer to reference a fake filesystem struct, and redirect pr_fsio_stat() to system() via a crafted RENAME request.
