Sophos SG UTM vulnerability
Remote code execution vulnerability in Sophos SG UTM WebAdmin interface allows unauthenticated attackers to execute arbitrary commands on affected systems.
Verdict
Today item — known-exploited.
A command injection flaw in the WebAdmin component enables remote code execution with high exploitability. The vulnerability is actively exploited in the wild and poses critical risk to network security appliances.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
7 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 0.96693 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Sophos, SG UTM. 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 identify the WebAdmin interface as publicly accessible and probe for injection points in request handling.
Business
Network perimeter security is compromised, allowing direct access to the security appliance management layer.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft a malicious request that injects shell commands into a vulnerable parameter, bypassing input validation.
Business
Attackers gain code execution privileges equivalent to the WebAdmin process, typically with system-level access.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute commands to establish persistence, exfiltrate credentials, or pivot to internal network resources.
Business
The compromised appliance becomes a beachhead for lateral movement, data theft, and further infrastructure compromise.
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.
