Description

alexusmai laravel-file-manager 3.3.1 and below is vulnerable to Directory Traversal. The unzip/extraction functionality improperly allows archive contents to be written to arbitrary locations on the filesystem due to insufficient validation of extraction paths.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly mitigates the insufficient validation of extraction paths by requiring validation of inputs to prevent directory traversal and arbitrary file writes.

SI-9 Information Input Restrictions good match
prevent

Restricts archive extraction paths to authorized directories only, blocking traversal attempts to arbitrary filesystem locations.

SI-2 Flaw Remediation good match
prevent

Requires timely remediation of the specific flaw in laravel-file-manager unzip functionality to eliminate the vulnerability.

Security SummaryAI

CVE-2025-65346, published on 2025-12-04, is a directory traversal vulnerability (CWE-22) in the alexusmai/laravel-file-manager package, affecting versions 3.3.1 and below. The flaw exists in the unzip and extraction functionality, which lacks sufficient validation of extraction paths, enabling archive contents to be written to arbitrary locations on the filesystem. This critical issue carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction. By uploading a malicious ZIP archive through the file manager's extraction feature, the attacker can achieve high confidentiality and integrity impacts, such as reading sensitive data or overwriting arbitrary files on the server, while availability remains unaffected.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
attack.mitre.org →
Why these techniques?

Directory traversal in unzip/extract allows arbitrary file writes (PR:N possible), enabling public-facing app exploitation (T1190) and web shell deployment for execution (T1100) and persistence (T1505.003) via PHP payloads in webroot.
