CVE-2025-61882
CVE-2025-61882 is a security flaw in Oracle E-Business Suite, Oracle’s software for running a company’s finances, supply chain and staff. Attackers are using a flaw in Oracle E-Business Suite 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 6 Oct 2025, and says ransomware gangs have used it.[1]
Oracle E-Business Suite 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. Oracle has published a fix or advice.
Description
CISA calls it an unspecified in Oracle E-Business Suite. In its words: “Oracle E-Business Suite contains an unspecified vulnerability in the BI Publisher Integration component. The vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Concurrent Processing. Successful attacks can result in takeover of Oracle Concurrent Processing.”[1]
The CVE record adds: “Vulnerability in the Oracle Concurrent Processing product of Oracle E-Business Suite (component: BI Publisher Integration). Supported versions that are affected are 12.2.3-12.2.14. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Concurrent Processing. Successful attacks of this vulnerability can result in takeover of Oracle Concurrent Processing. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).”[2]
The underlying weakness is improper authentication (CWE-287), 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 the organisation that published the CVE using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Oracle’s advisory has them[3]. CISA names the product as Oracle E-Business Suite.
Most families won’t have Oracle E-Business Suite; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 6 Oct 2025, within a day of it being made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 27 Oct 2025 to fix it.[1] CISA says ransomware gangs have used it.
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 over 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
Oracle has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]
- Check whether you use it.Oracle E-Business Suite 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 27 Oct 2025 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.
