This article is about a flaw in Apache HugeGraph-Server. For every flaw being used in attacks, see Exploited flaws; for Apache’s, see Apache flaws being used in attacks.

CVE-2024-27348 is a security flaw in Apache HugeGraph-Server, open-source software from the Apache Software Foundation. Attackers can run their own code on Apache HugeGraph-Server. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 18 Sep 2024.[1]

Apache HugeGraph-Server is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. Fixed in version 1.3.0.

Description

CISA calls it an improper access control in Apache HugeGraph-Server. In its words: “Apache HugeGraph-Server contains an improper access control vulnerability that could allow a remote attacker to execute arbitrary code.”[1]

The CVE record adds: “RCE-Remote Command Execution vulnerability in Apache HugeGraph-Server.This issue affects Apache HugeGraph-Server: from 1.0.0 before 1.3.0 in Java8 & Java11 Users are recommended to upgrade to version 1.3.0 with Java11 & enable the Auth system, which fixes the issue.”[2]

The underlying weakness is improper access control (CWE-284), in MITRE’s list of common software weaknesses.

It scores 9.8 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]

Most families won’t have Apache HugeGraph-Server; it’s for whoever looks after IT at work.

Exploitation

CISA added it to its catalog of known exploited vulnerabilities on 18 Sep 2024, 149 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 9 Oct 2024 to fix it.[1]

FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 99%. That’s in the top 1% of the flaws it scores.[4]

CISA assesses it as automatable: attackers can run it against many targets at once.

CISA doesn’t say who was attacked, or how.

Fix

Apache has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.”[1]

  1. Check whether you use it.Apache HugeGraph-Server is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
  2. Send this page to your IT person.Ask them to confirm it’s fixed (fixed in version 1.3.0), or not in use. CISA gave US government agencies until 9 Oct 2024 to fix it.
  3. If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.

You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
