Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 0.7% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

IBM Data Risk Manager versions 2.0.1, 2.0.2, 2.0.3, and 2.0.4 contain a directory traversal vulnerability tracked as CVE-2020-4430 and CWE-22. The flaw permits a remote authenticated attacker to submit a specially crafted URL that traverses directories and downloads arbitrary files from the underlying system. It received a CVSS v3.1 base score of 4.3, reflecting network attack vector, low complexity, and limited impact confined to confidentiality.

An authenticated remote attacker can exploit the issue by crafting malicious URL requests to the affected application, enabling unauthorized retrieval of files stored outside the intended web-accessible directories without requiring user interaction.

IBM has published an advisory at https://www.ibm.com/support/pages/node/6206875 addressing the vulnerability, and additional details appear in X-Force and full-disclosure mailing list references.

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.

SI-10 Information Input Validation
addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

PR.PS-02 partial match
blocks

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 none match
blocks

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.
