Rejetto HTTP File Server (HFS) vulnerability
A code injection vulnerability in Rejetto HTTP File Server's findMacroMarker function allows remote attackers to execute arbitrary programs without authentication.
Verdict
Today item — known-exploited.
Remote attackers can exploit unsafe macro processing in HFS to achieve arbitrary code execution. The vulnerability has been actively exploited in the wild and carries high exploitation likelihood. Organizations running affected HFS versions face immediate risk of system compromise.
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
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 0.99323 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Rejetto, HTTP File Server (HFS). Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-94 Code 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 HTTP request containing code injection payloads targeting the macro parser.
Business
The organization's file server becomes a vector for unauthorized code execution and potential lateral movement within the network.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I execute arbitrary programs on the compromised server with the privileges of the HFS process.
Business
Attackers gain persistent access, enabling data theft, malware deployment, or use of the server as an attack platform against other systems.
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.
