1) Path traversal (CVE-ID: CVE-2011-0049)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Green


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the _list_file_get function in lib/Majordomo.pm in Majordomo 2 before 20110131. A remote authenticated attacker can send a specially crafted HTTP request and remote attackers to read arbitrary files via .
