CVE-2018-14667
CVE-2018-14667 is a security flaw in Red Hat JBoss RichFaces Framework. Attackers can run their own code on Red Hat JBoss RichFaces Framework from anywhere, without logging in. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 28 Sep 2023.[1]
Red Hat JBoss RichFaces Framework 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. Red Hat has published a fix or advice.
Description
CISA calls it an expression language injection in Red Hat JBoss RichFaces Framework. In its words: “Red Hat JBoss RichFaces Framework contains an expression language injection vulnerability via the UserResource resource. A remote, unauthenticated attacker could exploit this vulnerability to execute malicious code using a chain of Java serialized objects via org.ajax4jsf.resource.UserResource$UriData.”[1]
The underlying weakness is code injection (CWE-94), in MITRE’s list of common software weaknesses.[2]
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]
Affected versions
NVD’s record doesn’t list version ranges for it; Red Hat’s advisory has them[3]. CISA names the product as Red Hat JBoss RichFaces Framework.
Most families won’t have Red Hat JBoss RichFaces Framework; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 28 Sep 2023, 1,787 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 19 Oct 2023 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 74%. 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
Red Hat 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]
- Check whether you use it.Red Hat JBoss RichFaces Framework 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.
- Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 19 Oct 2023 to fix it.
- 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.
