Deeper analysis AI-assisted summary

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

A vulnerability in the CLI of Cisco SD-WAN Software stems from improper access controls on commands. This flaw, tracked as CVE-2022-20775, enables an authenticated local attacker to execute arbitrary commands with elevated privileges on affected systems. The issue carries a CVSS score of 7.8 and is associated with CWE-25 and CWE-22.

An authenticated local attacker can exploit the weakness by submitting a maliciously crafted command through the application CLI. A successful attack grants the ability to run arbitrary commands as the root user, potentially leading to full system compromise.

Cisco has published software updates that remediate the vulnerability, and the vendor states that no workarounds are available. The primary advisory is available at the Cisco Security Advisory link referenced in the CVE record.

EPSS scores for this CVE rose from a low baseline to a recorded peak of 0.0104, indicating emerging exploitation interest 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.

addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that prevent traversal flaws.

PR.PS-02 partial match
prevents

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
prevents

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

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Secure coding standards require canonicalization and neutralization of '../' sequences in path construction.

finds

Security testing in development catches path-traversal flaws before production deployment.

prevents

Secure development lifecycle mandates input validation and path sanitization that directly prevents traversal sequences.

prevents

Application security requirements explicitly call for controls against path traversal and directory escape attacks.

prevents

Secure architecture principles reduce exposure to path traversal through least-privilege file-system design.

mitigates

Information access restriction limits which directories users or processes may traverse.
