Summary

CVE-2025-26349 is a high-severity Relative Path Traversal (CWE-23) vulnerability in Q-Free Maxtime. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Ingress Tool Transfer (T1105); ranked in the top 35.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly validates file paths and filenames in upload requests to block relative path traversal exploits like CWE-23.

prevent

Remediates the specific path traversal flaw in Q-Free MaxTime's file upload mechanism through timely patching.

detect

Verifies integrity of critical files to detect unauthorized overwrites from successful path traversal exploitation.

MITRE ATT&CK Enterprise TechniquesAI

T1105 Ingress Tool Transfer Command And Control
Adversaries may transfer tools or other files from an external system into a compromised environment.
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.
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
T1554 Compromise Host Software Binary Persistence
Adversaries may modify host software binaries to establish persistent access to systems.
Why these techniques?

Path traversal in file upload enables arbitrary file overwrites, facilitating ingress tool transfer (T1105), exploitation of public-facing app (T1190), web shell deployment (T1505.003), and binary compromise (T1554).

NVD Description

A CWE-23 "Relative Path Traversal" in the file upload mechanism in Q-Free MaxTime less than or equal to version 2.11.0 allows an authenticated remote attacker to overwrite arbitrary files via crafted HTTP requests.

Deeper analysisAI

CVE-2025-26349 is a CWE-23 Relative Path Traversal vulnerability in the file upload mechanism of Q-Free MaxTime versions less than or equal to 2.11.0. Published on 2025-02-12T14:15:34.960, it carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). The issue enables an authenticated remote attacker to overwrite arbitrary files through crafted HTTP requests.

An attacker requires high privileges (PR:H) to exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation allows overwriting arbitrary files, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U).
