Summary

CVE-2025-26354 is a high-severity Path Traversal: '.../...//' (CWE-35) vulnerability in Q-Free Maxtime. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 15.4% 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).

Deeper analysis

Q-Free MaxTime versions 2.11.0 and earlier contain a path traversal vulnerability (CWE-35) in the copy endpoint of maxtime/api/database/database.lua. The flaw allows an authenticated remote attacker to supply crafted HTTP requests that overwrite arbitrary files on the underlying system. It is tracked as CVE-2025-26354 and carries a CVSS 3.1 base score of 7.2.

An attacker who already possesses valid credentials can leverage the endpoint to modify sensitive configuration or data files, resulting in high impact to confidentiality, integrity, and availability without any user interaction required.

The referenced Nozomi Networks advisory at https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2025-26354 supplies additional technical context and recommended actions for affected deployments. The associated EPSS values have remained low, with a current score of 0.0214 and a recorded peak of 0.0269.

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
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.
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.
Why these techniques?

Path traversal in the API copy endpoint enables authenticated remote file overwrite on sensitive files, facilitating exploitation of public-facing application (T1190), privilege escalation (T1068), and stored data manipulation via corruption (T1565.001).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly prevents path traversal attacks by enforcing validation of input parameters in the copy endpoint to block crafted requests that overwrite sensitive files.

prevent

Addresses the vulnerability through timely flaw remediation, such as applying patches for the path traversal issue in maxtime/api/database/database.lua.

prevent

Mitigates exploitation risk by enforcing least privilege, limiting the number of high-privilege (PR:H) authenticated users able to access and abuse the vulnerable copy endpoint.
