CVE-2020-11738
Path Traversal in Awesomemotive Duplicator ≤ 1.3.28
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2020-11738 is a high-severity Path Traversal (CWE-22) vulnerability in Awesomemotive Duplicator. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.
The vulnerability is a path traversal flaw, tracked as CWE-22, that affects the Snap Creek Duplicator plugin for WordPress prior to version 1.3.28 and Duplicator Pro prior to 3.8.7.1. Untrusted input supplied in the file parameter to the duplicator_download or duplicator_init actions is not properly sanitized, allowing sequences such as "../" to escape the intended directory.
An unauthenticated remote attacker can exploit the issue over the network with low complexity to read arbitrary files on the underlying server, resulting in disclosure of sensitive configuration data, credentials, or other hosted content. The CVSS 3.1 score of 7.5 reflects the absence of required privileges or user interaction and the high confidentiality impact.
Vendor advisories and the official changelog recommend immediate upgrade to Duplicator 1.3.28 or Duplicator Pro 3.8.7.1. Public exploit code has been released on PacketStorm, and Wordfence has documented active exploitation campaigns targeting more than one million sites that had not yet applied the patch.

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.
