NAKIVO Backup and Replication vulnerability
NAKIVO Backup and Replication contains an absolute path traversal vulnerability allowing attackers to read arbitrary files from affected systems.
Verdict
Today item — known-exploited.
An unauthenticated or low-privileged attacker can exploit path traversal to access sensitive files outside intended directories, potentially exposing credentials, configuration data, or other confidential information stored on the backup server.

Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
260 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-03-19).
Probability (EPSS)
EPSS 0.94265 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 8.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N) · Affected: NAKIVO, Backup and Replication. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-36 Absolute Path Traversal — weakness family: Path traversal / file.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: yes · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 15 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.
Public exploit available
Public exploit tooling is catalogued for this CVE (a public proof-of-concept / detection template). Catalog entries: nuclei template. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious request using absolute path sequences to bypass directory restrictions and access files outside the application's intended scope.
Business
Sensitive backup metadata, encryption keys, or customer data become accessible to unauthorized parties, creating compliance violations and data breach liability.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I enumerate system files and configuration to identify credentials, API tokens, or database connection strings stored on the backup appliance.
Business
Compromised credentials enable lateral movement into production infrastructure, multiplying the scope and severity of the security incident.
3
Lateral reach — past segmentation narrative 3
Attacker
I extract backup catalogs or metadata to map organizational infrastructure, backup schedules, and recovery procedures for targeted extortion or follow-on attacks.
Business
Attackers gain operational intelligence to conduct more effective ransomware deployment or supply chain compromise against customers relying on these backups.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
