Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-35840 is a path traversal vulnerability (CWE-22) in the _joinPath function within elFinderVolumeLocalFileSystem.class.php of the PHP LocalVolumeDriver connector. It affects elFinder versions prior to 2.1.62 and carries a CVSS 3.1 base score of 6.5.
An attacker with low-privileged network access and no user interaction required can exploit the flaw to perform unauthorized file modifications on the server, resulting in high integrity impact without affecting confidentiality or availability.
The referenced GitHub security advisory and the commit bb9aaa7b096a1b83f2f85657c43f12131ece2891 indicate that the issue is resolved by upgrading to elFinder 2.1.62 or later; public proof-of-concept repositories further document the path traversal vector in the LocalVolumeDriver.
EPSS remains flat at 0.0626 with no material increase after disclosure.

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.
Validates pathnames and filenames to prevent traversal outside intended directories.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
