rConfig vulnerability
rConfig contains an OS command injection vulnerability in ajaxAddTemplate.php that allows remote attackers to execute arbitrary OS commands via shell metacharacters in the fileName POST parameter.
Verdict
Today item — known-exploited.
A remote attacker can inject OS commands through the fileName parameter to achieve unauthenticated code execution on the rConfig server, leading to full system compromise and data exfiltration.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
1 independent public report 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 2021-11-03).
Probability (EPSS)
EPSS 0.36754 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: rConfig, rConfig. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-78 OS Command Injection — weakness family: Injection.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 a malicious POST request with shell metacharacters embedded in the fileName parameter to break out of the intended command context.
Business
The organization loses control of the rConfig server and all systems it manages, enabling lateral movement and data theft.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary OS commands with the privileges of the rConfig application process to establish persistence and enumerate the environment.
Business
Attackers gain persistent access to critical network infrastructure and can pivot to other systems, increasing breach scope and recovery costs.
3
Lateral reach — past segmentation narrative 3
Attacker
I exfiltrate sensitive configuration data, credentials, and device management information stored within rConfig.
Business
Confidential network topology, device credentials, and operational data are exposed, enabling further targeted attacks across the organization.
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.
