Vulnerability Data
This vulnerability allows remote attackers to delete sensitive files on vulnerable installations of Mitel MiVoice Office 400. Authentication is required to exploit this vulnerability. The specific flaw exists within the web portal listening on TCP port 443, under Maintenance →…
more
File Management → File Browser, which is affected by a directory traversal vulnerability. By exploiting this vulnerability, an authenticated attacker can access and delete files outside of the intended directory, including files belonging to the Mitel application and the underlying Linux system. Deleting critical system or application files can result in a denial-of-service condition affecting the underlying system.

Mitigating Controls (NIST 800-53 r5) AI
Enforces authorization checks on file/resource access, blocking exploitation of a traversed path even if the malformed name is accepted.
Enforces information flow rules that can deny access to locations outside the intended directory.
Directly requires validation of path inputs, stopping the acceptance of backslash dot-dot sequences that escape the restricted directory.

Secure SDLC practices directly require input validation and path sanitization that block this weakness.

Secure development lifecycle mandates input validation and path sanitization that directly blocks directory traversal sequences.
A.8.26 only requires that security requirements (including resilience against SQLi or buffer overflows) be identified and specified during development or acquisition; it does not itself neutralize path traversal sequences or stop exploitation of CWE-31.
Secure architecture principles reduce the attack surface but do not prescribe the specific coding fix.
Secure coding standards require canonicalization and whitelist validation that eliminate CWE-31.
