The Update: Oracle confirmed that the zero day vulnerability had been exploited and released an out-of-cycle patch to address it. Security researchers linked the attacks to data theft and extortion activity associated with the Cl0p ransomware group.
Following a wave of cyber extortion attempts, Oracle warned that some E-Business Suite customers had received threatening emails after the attacks. The company has urged all users to apply the patch immediately and released indicators of compromise to help organisations identify potential breaches.
"Our ongoing investigation has found the potential use of previously identified vulnerabilities that are addressed in the July 2025 critical patch update." - Rob Duhart, Chief Security Officer at Oracle Security
The flaw affects Oracle E-Business Suite versions 12.2.3 through 12.2.14. The UK’s National Cyber Security Centre has also advised organisations to update their systems promptly because of the severity of the vulnerability.
Why It Matters: E-Business Suite plays a crucial role in managing sensitive financial, customer and operational data across thousands of businesses globally. A successful exploitation could allow attackers to access or steal this information.
The confirmed involvement of the Cl0p group, which has previously carried out major data extortion campaigns, increases the risk for affected organisations. This incident highlights the growing challenge of zero day exploitation and reinforces the importance of timely patching and continuous security monitoring within enterprise environments.
