LogicalDOC Enterprise 7.7.4 Multiple Post-Authentication Directory Traversal Vulnerabilities

LogicalDOC Enterprise 7.7.4 contains multiple post-authentication file disclosure vulnerabilities that allow attackers to read arbitrary files through unverified 'suffix' and 'fileVersion' parameters. Attackers can exploit directory traversal techniques in /thumbnail and /convertpdf endpoints to access sensitive system files like win.ini and /etc/passwd by manipulating path traversal sequences.
