Vulnerability details

A vulnerability in QCMS version 6.0.5 allows authenticated users to read arbitrary files from the server due to insufficient validation of the "Name" parameter in the backend template editor. By manipulating the parameter, attackers can perform directory traversal and access…

sensitive files outside the intended template directory, potentially exposing system configuration, PHP source code, or other sensitive information.

CWE(s)

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
Why these techniques?

Authenticated directory traversal enables arbitrary file reads from the local system, such as configuration files (e.g., Config.ini), PHP source code, and system files (e.g., hosts), facilitating data collection (T1005) and access to unsecured credentials in files (T1552.001).

addresses: CWE-20

Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.

addresses: CWE-20

Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.

addresses: CWE-20

Directly implements checks on information inputs to reject invalid data before processing.

addresses: CWE-20

Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
