CVE-2012-0518
CVE-2012-0518 is a security flaw in Oracle Fusion Middleware, Oracle’s business software. Attackers are using a flaw in Oracle Fusion Middleware that its maker hasn't described in detail. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 28 Mar 2022.[1]
Oracle Fusion Middleware 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.
Description
CISA calls it an unspecified in Oracle Fusion Middleware. In its words: “Unspecified vulnerability in the Oracle Application Server Single Sign-On component in Oracle Fusion Middleware allows remote attackers to affect integrity via Unknown vectors”[1]
The CVE record adds: “Unspecified vulnerability in the Oracle Application Server Single Sign-On component in Oracle Fusion Middleware 10.1.4.3.0 allows remote attackers to affect integrity via unknown vectors related to Redirects, a different vulnerability than CVE-2012-3175.”[2]
The underlying weakness is open redirect (CWE-601), in MITRE’s list of common software weaknesses.
It scores 4.7 out of 10 on the Common Vulnerability Scoring System, which rates it medium, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it. CISA names the product as Oracle Fusion Middleware.
Most families won’t have Oracle Fusion Middleware; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 28 Mar 2022, 3,450 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 18 Apr 2022 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 5%. That’s in the top 9% of the flaws it scores.[3]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
CISA’s required action: “Apply updates per vendor instructions.”[1]
- Check whether you use it.Oracle Fusion Middleware 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 18 Apr 2022 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.
