Cisco Prime Data Center Network Manager (DCNM) vulnerability
Directory traversal vulnerability in Cisco Prime DCNM fmserver servlet allows remote attackers to read arbitrary files on affected systems.
Verdict
Today item — known-exploited.
A path traversal flaw in the fmserver servlet component of Cisco Prime Data Center Network Manager enables unauthenticated remote file access. The vulnerability has been exploited in the wild and carries moderate exploitability risk.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
9 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 2022-03-25).
Probability (EPSS)
EPSS 0.40608 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Cisco, Prime Data Center Network Manager (DCNM). Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-22 Path Traversal — 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 craft HTTP requests with directory traversal sequences to the fmserver servlet endpoint.
Business
Sensitive configuration files, credentials, and operational data stored on the DCNM server become accessible to unauthorized parties.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I extract authentication tokens, API keys, and database connection strings from readable system files.
Business
Lateral movement and privilege escalation attacks against connected infrastructure become feasible through compromised credentials.
3
Lateral reach — past segmentation narrative 3
Attacker
I read application source code and configuration to identify additional vulnerabilities in the data center management environment.
Business
The attack surface expands, increasing risk of cascading compromises across managed network devices and services.
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.
