Cisco SD-WAN vulnerability
Cisco SD-WAN CLI contains a path traversal vulnerability allowing authenticated local attackers to bypass access controls and execute arbitrary commands with root privileges.
Verdict
Today item — known-exploited.
An authenticated local attacker can exploit improper access controls in SD-WAN CLI commands to traverse the filesystem and execute arbitrary code with elevated privileges, potentially compromising system integrity and confidentiality.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
8 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 2026-02-25).
Probability (EPSS)
EPSS 0.12475 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Cisco, SD-WAN. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-25 CWE-25, CWE-282 CWE-282 — weakness family: Path traversal / file.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
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 authenticate to the SD-WAN CLI as a standard user with limited privileges.
Business
Legitimate user accounts are provisioned for operational access to network appliances.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft a path traversal payload in a CLI command to bypass directory restrictions.
Business
Access control enforcement on CLI commands fails to validate or sanitize user input.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute the malicious command and gain root-level code execution on the device.
Business
The SD-WAN appliance is fully compromised, allowing the attacker to modify configurations, exfiltrate data, or pivot to connected networks.
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.
