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-2023-32563 is a path traversal vulnerability (CWE-22) affecting the RemoteControl server component of Ivanti Avalanche. The flaw carries a CVSS 3.1 score of 9.8 and permits unauthenticated remote code execution when an attacker supplies crafted input that traverses directories on the server.

An unauthenticated attacker with network access can exploit the issue without user interaction or credentials, resulting in full compromise of confidentiality, integrity, and availability on the affected system. The attack vector is rated as network-accessible with low complexity.

Ivanti’s advisory states that the vulnerability is resolved in Avalanche 6.4.1; administrators are advised to apply the update to eliminate the RemoteControl server exposure.

The associated EPSS score has reached a peak of 0.9336 and currently sits at 0.9301, indicating sustained and substantial exploitation interest following disclosure.

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-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.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
