MITRE ATT&CK Enterprise Techniques

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.
T1083 File and Directory Discovery Discovery
Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.
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.
T1574.007 Path Interception by PATH Environment Variable Stealth
Adversaries may execute their own malicious payloads by hijacking environment variables used to load libraries.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-73

Rejects externally supplied file or resource identifiers that fail validity checks.

PR.PS-06 full match
prevents

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

PR.AA-05 mostly match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

prevents

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
